Promo Video for Manilla Slope Fest 09 in NSW, Austrailia

Hey, Guys, here’s the Promo video that’s been made for the the Manilla Slope Fest after a Recon mission over the June Longweekend here in Australia. This is BIG SKY country  with an astroturfed launching area facing 4 directions of the compass. The event now has 5 Sponsors being North Queenland radio control, Falcon Gliders, AirsportsRC, Windrider and RCmodelair. The event is gaining momentum and now, with this sneak peak of the site and what its like, we will hopefully entice more slope flyers out of the wood work.

I hope you enjoy the Video!
Many thanks to Andrew for putting it together.
Regards,  Steve Wenban

Manilla Slope Fest 09 in NSW, Austrailia

Stephen form the West Sydney Slope Soarers sent in this note about an event in Austrailia.

I’m the President of the WSSS and just wanted to get the word out about that the WSSS have secured the use of Mt Borah near Tamworth NSW for Manilla Slope Fest 09 September 20th to the 28th. Site information can be found here

This will be the inaugural event and we plan on making it an annual get together. We already have 1 huge event In January at Camperdown in Victoria but having to wait 12 months for a get together of slope flyers we thought we would do a little research and came up with this site. It’s actually a Parra and Hang glider site where they do there record attempts for cross country and they held the 2007 Parra Gliding World Championships there. It has 4 huge launch sites covered with astro turf  making the perfect runway for scalies.

So, there it is, it’s open to all flyers not just Aussie ones could be that perfect slope /family holiday in Australia for some of our international slope brothers and sisters.

For any other information regarding the slope fest our West Sydney Slope soarers home page will carry updates regarding the progress of the event.

Best Regards.

Viking Race 2006 is Now Complete

The Viking Race 2006, held this time in Scotland, is now complete. Looks like five rounds of racing, with one discard,  which is not what the competitiors were looking for. A minimum of ten rounds is what they hoped for. Some days of light wind, and a couple of rain, tempered the competition. Still, the results show that the cream always rise to the top.

Kansas F3F – August 2005

We got in a 4-round F3F race on Saturday the wind was very light, 4-7mph or so when we started and it got lighter as we went. Thermals did make the course flyable most of the time. Probably not even “legal” wind most of the time but we could fly and figured the light air practice would be better than nothing so we set up the course and proceeded to run the race.

We flew on the ENE face of Airport Hill at Wilson Lake in Central Kansas. This site has good potential if the wind comes up and is the right direction. Not real common wind direction this time of tear but it was good to see that the site will work and early season events may see ENE more often.

Ian and Andrew made the trip to central Kansas from Colorado. Greg drove from Milwaukee and the rest of the guys were local or from not too far away.

Todd and Mike both got some of the better air and that, along with some good flying, got them both their best results to date. Eric was making some really nice turns and just missed besting Jack! Watch your 6, Jack, guys are gunning for you. Chance is improving as well. Ian and Andrew got their feet wet and both showed promise. If the wind had been better I think Ian would have been very competitive. Andrew got the long walk when he landed the Discus out.

Since we started doing F3F in Kansas it has grown quite nicely. If the forecast would have been more favorable we should have had at least 12 racers, Maybe as many as 15! We are also starting to see guys running much better courses and making the commitment to get a dedicated F3F plane. I expect to see this keep growing!

Here is how they finished.

Kansas F3F – July 2005

We had a good day of racing in central Kansas on Saturday. 10 rounds of action at two different slopes made up the competition.

We started the day with a southwest wind and raced 4 rounds of thermal lottery at the German Caves. The Caves are a 200 plus foot limestone bluff facing southwest. Jeff had good air and a good plane in his Image for the light, thermally conditions and set the early pace. If the competition had ended there he’d have been the king.

Erik’s Banana at the Caves.

Merrel rounding Base B at the Caves.

About 2PM the wind had shifted enough southeast to go the main slope at Wilson Lake, site of the Midwest Slope Challenge, and resume the competition. We flew an additional 6 rounds there and for the final standings combined both venues into a single score. 10 rounds with one throw out. At the end of the day Greg narrowly edged out Jack with Mike third.

Kudos to Jack who was really competitive with a 60-inch MiniBlade. He was consistently flying the shortest course possible and wringing that little plane for all it was worth and if that weren’t enough for the MiniBlade, he proceeded to wrap it up fast in the DS groove at the dam after the event.

Merrel and Mike both broke into the 50’s with Mike having a fastest round.

Pat and Randy traded off with Randy’s Nemesis after Pat’s Tragi suffered a cracked tail boom while Pat also used his ODR Fun-1 for some good times.

Erik and Chance flew fast but a bit long on the course. With some practice they will be in the hunt.

All Jeff needs to be very competitive is a more capable plane. The Image shined in the light air but suffered when the wind at the lake came up and was crossing the slope at up to 30 degrees.

Me missed Mr.Clean at the Lake slope but he will be back for the next one!

In 10 rounds there were 5 guys who had fasted time for the round. Everyone had a blast and this was the largest turnout we’ve had for an F3F in Kansas with 12 registered and 10 actually racing. Several guys experienced their first event and showed marked improvement over the day. Here’s hoping for more participation in the future.

We are going to try to get in more racing on Sunday. We’ll see how it goes.

Midwest Slope Challenge 2005 Report

All the elements for a great Midwest Slope Challenge were in place. Over 50 pilots, a great site, lots of planes. Only one real problem, not much wind on contest days. No matter, that did not keep the assembled slopers from having a great time, with most vowing to return next year.

Thursday, before the official start of the event, was great, 20-25 mph winds and lots of flying. I flew a ton of stuff. ‘Cuda, Erwin 5, Opus, RaceM and Fun-1 to name a few. Pat McCleave had his new LEG Reno Racer Mustang out and it looked great. The extra detail the sponsor words provide make it look excellent in the air. Todd had his LEG P-63 going well. Jack flew the heck out of his 72-inch design, the Corssover. Lots of other guys were out flying all day the lift was really working well and as the evening progressed the air smoothed out for a super finish to an awesome day.

Friday was a rain out with a few flights thrown in between the drops. Lots of building happened at the LEG shop. Electrics and DLGs were seen in abundance. Jim Porter got out his big, honkin’ bungee and was launching his X-21 into the thermal lift.

Pat McCleave’s LEG Mustang


Saturday started with the Combat event. There was little wind at the end of Airport Hill but I like a low wind combat event. It keeps every one down low where Combat belongs. That said another 5mph would have been perfect. Somehow I managed to win with a CombatWings XL. Because the MWSC rules allowed for it I switched to a Weasel for round 3 to try it out! Pretty fun. Emil Weiler took 5th with his Weasel with which he flew every round!

Saturday afternoon we moved to a better hill and had the ODR competition. Light but flyable wind most of the time. If a thermal came through during your heat there was some pretty good racing. Other times it was a survival event. Again, I managed to win this one despite there being some really good pilots nipping at my heels. The light conditions favored  lighter models and building straight and true is never more important than when the lift is light! Don’t worry, the winning Fun-1 will not be back in the same form. I folded the wing DSing it on Monday. The fuse survived though so Son of Fun-1 will return with a change I’ve been wanting to make anyway.

Todd Martin’s P-63


Sunday started out dreary with light wind so the Unlimited and Warbird races were cancelled. For those who stayed the wind turned on about 2 PM and the conditions were great!

In any case it was fun to see old friends and get to fly with them again. For me this contest is as much or more about the people as it is about the flying. That said I’d like to have had a shot at those other two trophies!

Monday was an epic day as we had 40mph plus winds hitting the DS slope dead on and then, after most of our planes became unflyable for one reason (tree) or another (stripped servos, etc.) we headed to a super secret slope on a private ranch that is 300 feet high with the last 100 shear limestone. Truly spectacular!

Columbus Day 2004 – Wilson Lake, Kansas

Greg and Mirko took a trip to Wilson Lake, Kansas for what has become a tradition, the Columbus Day slope get together at one of the Midwest’s best known slope sites.

Mirko and I left Milwaukee dark and early on Thursday at 5 AM for the 12 hour drive to Wilson Lake near Lucas, Kansas. We took a different route that I had been using in the past and it seems like a better way to go. Basically I-80 to York, Nebraska and then south on US-81 which is now 4-lane all the way to Salina, Kansas. Very nice.

We got to the lake about 5:30 PM and met a few guys just packing it up for the day. We were still in for a couple of hours of flying! We didn’t drive all this way for nothing! The highlight for me was the first flight of my Erwin 5. The wind was light but it was “magic air”, the buoyant air at the end of the day, and the Erwin loved it. I spent quite a bit of the remaining daylight sorting and tweaking.

After it got dark we headed over to Jack Cooper’s new home and the new shop for Leading Edge Gliders. Very nice!

Mirko Reports on the 2004 Soar Utah Event


Greg and I left Milwaukee late Monday afternoon, the 30th of August for our latest Safari with Salt Lake City as our final destination. We had plans to fly the Chamberlain, SD area, (depending on the wind direction) and wherever we could in Wyoming. We picked up Emil in Sioux Falls the next morning and headed over to the Missouri River, a two hour drive, just south of Chamberlain.

When we got there, we were greeted with no wind, and stifling heat. Temperatures would run into the 90s for the next several days until we got to Salt Lake City. I did a little hand tossing of my new PIXEL, testing the trim, and found it perfect. Emil, and Greg, were also launching with no results, so the three amigos decided to push on to other unexplored areas on the way to our final stop: Templetown, aka Salt Lake City.

We worked our way along I-90 westward and just after Kadoka, SD, we exited on state HWY 73 toward Philip, up to Billsburg, through Hartly, then still staying on 73 stopped above the Cheyenne River where we found bluffs facing west to north. This was before the descent to the bridge. It was a 50 to 100 yard walk to this face. Greg and Emil flew here for a while, but winds were light. After about an hour here we moved on to Howes where we continued on HWY 34 to White Owl, Enning, Union Center, then found a spot near where the road crossed the Belle Fourche River just around Volunteer. We called this spot “Junkyard hill,” due to a pile of junked cars near where Greg and Emil flew their planes while I languished near the van. On this day I found the heat too grim to fly, especially with such light winds.

After about a half hour of that we kept moving west on HWY 34 to Sturgis where we rejoined I-90 and headed on to Wyoming to Gillette, where we had supper, then finally to Buffalo, where we found a motel for the night.

The next morning, September 1st, while having breakfast in Buffalo, Greg noticed a big hill just outside of town. This was just west of Buffalo on HWY 16. We drove up a dirt road to a fairly good site, but again, the wind was inconsistent, and light. So we departed westward on HWY 16 for the southern pass of the Bighorn Mountains. Taking the Cloud Peak Scenic Byway over the Powder River pass, we finally came to a gravel parking area in Ten Sleep Canyon. Here we flew for about 45 minutes with a pretty decent wind coming up the canyon.

Next, we passed Worland, then moved on to Thermopolis and the Wind River Canyon. Here we found a dirt (what else!) road on BLM land leading to another series of bluffs overlooking a valley and the road below. Plenty of wind here but to me the lift was very uneven. Due to a hill about a half-a-mile across the valley, there was a lot of rotor coming in front of this 200 ft bluff. So we left here after about an hour, and moved on with all three of us giving different explanations for the uneven lift at this site.

It was mid-afternoon and we hit the road for Evanston, but on the way by way of HWY 20, to Shoshoni, then HWY 26 to Riverton, then Hwy 789 to Lander, and from there HWY 28, where 16 miles from Lander we found the best spot of this two day slope hunt. This was Red Canyon Rim. We pulled off the road and parked next to the guardrail; a barbed wire fence kept you from falling off the slope edge; there was a nice large flat landing zone to the left of our launching area, but on the other side of the fence. The wind was light but consistent from the NW. This slope should work WNW to NNW. Greg and Emil flew Weasels and Pixels while I took pictures. After flying for a while, we all wished that we would have found this spot earlier in the day. The light, late afternoon winds were producing great lift. Notable names adjacent to this area were Young Mountain, Limestone Mountain, and Iron Mountain. This was north of I-80 halfway between Rawlins and Rock Springs.

We rejoined I-80 at Rock Springs and went on to Evanston where we found a motel for the night. The next morning Thursday, we headed for Temple Town, about 80 miles away.

Soar Utah 2004 Mini Report

Mirko, Emil and I arrived on Thursday about noon and headed to Point of the Mountain. The wind was good and the lift was building. With a minor exception on Saturday AM we have had great flying conditions at POM North for the last three days. This is truly one of the very best slopes in the country.

Brian Laird’s BD-5 ripping it up on Thursday

Lots of PSS action. Some big scale ships and a whole slew of slopers are flying. The conditions mean that you can fly just about anything you brought. I had 20 ounces in the already 57 ounce Opus and could have added the wing ballast as well.

Of note to a few of us Mirko finally, after almost 3 years, got the first flight on his 4.3 Meter ASW-15B. The flight was almost anticlimatic. Owing to the 17 pound weight, and Mirko’s experience launching big tubs, he decided to do the launch duties while I did the flying duties. Thanks, Mirko! So, Mirko, with a herculean effort, threw the big ship into the lift. I jabbed down on the elevator and built up some speed and then didn’t touch the stick for about 10 seconds. The plane just flew straight and true, climbing a bit. It needed some significant down trim but after that I tooled around for a couple minutes gaining several hundred feet getting the feel of the plane. About 2 minutes into the flight, and feeling confident in the planes abilities, I dove it down and checked the roll rate. Not fast but it sure was cool to see the big ship do a nice roll! Mirko, having recovered from his launch effort glommed on to the transmitter after I had been flying and trimming for about 5 minutes. Must be nice to get a trimmed out plane when you waited three years to fly it! He sure looked happy! Guess the drive to Utah was worth the trip! So easy to fly was the ASW-15 that Mirko even handed the transmitter to Emil for a bit. Very nice flying tub.

Mirko’s 4.3 meter EMS ASW 15B

I’ll be doing a more detailed report when I get home. I have a bunch of photos and will post those as well. Stay tuned!

Midwest Slope Challenge 2004 Coverage

The Midwest Slope Challenge 2004 was one of the best on record and THE best I’ve attended in my 5 years of going to the contest. I arrived a couple of days early this year and stayed a couple of days afterward. I plan to do the same next year. Some of the best times of the weekend were non competition happenings and I look forward to more of the same.

Note: I’ve included a few pix with this story but there is a big gallery of 247 pix that is available here.

I was able to get going at 5:30 AM and of the 12-hour drive to Kansas from Milwaukee, I spent 11:38 in the vehicle! 2 gas stops and that was it. The idea was to get some flying in before dark on Wednesday.

The wind was north when I arrived at Palmer’s Pasture at 6PM or so. There were a few guys flying including Jim Porter who was flying his Elita.

Midwest Slope Challenge 2003 Coverage

Another MWSC is in the books. This was the 10th Annual event and has become one of the biggest slope pilot gatherings in the US. Nearly 60 pilots from 13 states as well as Germany and England made the trip to central Kansas for several different events run over 4 days.

A photo gallery with over 300 pix is available here.

Pilots started arriving on Sunday, almost a full week before the competitive events, to fly the slope overlooking Wilson Lake, KS. Some of the early arrivals included New York Slope Dogs Dave Garwood and Joe Chovan, Fred, Mike and Ed form Colorado, Larry from Tennesse, Duane from North Carolina and Denny from Pennsylvania. With trip distances like these the guys want to make sure that they get in some good flying. Reports from Monday and Tuesday made me wish I had arrived a day or two earlier.

I got to Lucas, KS on Tuesday night about 10:30PM after a 13-hour drive from Wisconsin and found a chair-sleeping Denny Maize of Polecat Aero already at the accomodations for the week, Mayor Dave’s country house. After I rousted the big guy, we sat on the lower deck for a bit and knocked back a couple of cold ones while catching up on the year since we were here last. We hit the sack looking forward to some sloping in the AM.

F3F Competition Rules


5.F.1.       Definition: This contest is a speed event for radio controlled slope gliders. A minimum of four rounds must be flown. The organiser shall run as many rounds as the conditions and time permit, up to a maximum of ten rounds.

5.F.2.       Characteristics of Radio Controlled Slope Gliders

Maximum surface area (St) …………..150 dm2
Maximum flying mass …………………….5 kg
Loading on St ………..between 12 and 75 g/dm2

The radio shall be able to operate simultaneously with other equipment at the normally used spacing in the allocated R/C bands (i.e. 35 MHz : 10 kHz).

The competitor may use two models in the contest. The competitor may combine the parts of the models between the rounds provided the resulting model used for flight conforms to the rules and that the parts have been checked before the start of the contest. Addition of ballast (which must be located internally in the model) and/or change of angles of setting are allowed. Variation of geometry or area is allowed only if it is actuated at distance by radio control.

5.F.3.       Competitor and Helpers: The competitor (pilot) must operate his radio equipment personally. Each pilot is permitted one helper. The helper is only to assist and advise the pilot until the model is passing Base A for the first time and after the timed flight is completed.

5.F.4.       Definition of an Attempt: There is an attempt when the model has left the hands of the pilot or his helper.

5.F.5.       Number of Attempts:  The pilot has one attempt on each flight. An attempt can be repeated if:
a)     the launching attempt is impeded, hindered or aborted by circumstances beyond the control of the pilot, duly witnessed by the official judges;
b)    his model collides with another model in flight or other impediment and the pilot is not to blame on that account;
c)     the flight was not judged by the fault of the judges.

5.F.6.       Cancellation of a Flight: A flight is official when an attempt is carried out, whatever result is obtained.

A flight is official but gets a zero score if:
a)    the pilot used a model not conforming with FAI rules;
b)    the model loses any part while airborne;
c)    the helper advises the pilot during the timed flight;
d)    the model is controlled by anyone other than the pilot;
e)    the flight is not carried through;
f)     the model lands outside the assigned landing area;
g)    the model is not launched within one minute from the moment the starting order is given.

5.F.7.       Organisation of Starts:  The flights are to be performed round by round. The starting order is settled by draw in accordance with the radio frequencies used.
The pilot is entitled to three minutes of preparation time from the moment he is called to the ready box.
After the three minutes has elapsed, the starter may give the order to start. After the starter has given the order to start, the pilot or his helper is to launch the model within one minute. The pilot or his helper is to launch the model by hand from the starting area indicated by the organiser.
If possible, the starting area, including the audio system, shall be situated in the middle of the course  (equal distance from Base A and Base B).
The time from launch to the moment the model enters the speed course must not exceed thirty seconds.
If the model has not entered the speed course (i.e. first crossing of Base A in the direction of Base B)] within the thirty seconds, the flight time will commence the moment the thirty seconds expires. If the model has not entered the speed course within the thirty seconds, this is to be announced by the judges.

5.F.8.       The Flying Task:  The flying task is to fly 1000 metres on a closed speed course of 100 metres in the shortest possible time from the moment the model first crosses Base A in the direction of Base B.

5.F.9.       The Speed Course:  The speed course is laid out along the edge of the slope and is marked at both ends with two clearly visible flags. The organiser must ensure that the two turning planes are mutually parallel and perpendicular to the slope.
Depending on the circumstances, the two planes are marked respectively Base A and Base B.
Base A is the official starting plane. At Base A and Base B, an Official announces the passing of the model  (i.e. the centre of gravity) with a sound signal when the model is flying out of the speed course. Furthermore, in the case of Base A, a signal announces the first time the model is crossing Base A in the direction of Base B.

5.F.10.     Judging:  The flights are judges by two judges who do not have to be the same for all competitors.
The judges’ task is to control that the flights are performed according to the rules, to be time keepers and to ensure that the right distance is flown.

5.F.11.     Scoring:  The result of the flight is stated as the time in seconds and hundredths of seconds obtained by each pilot. For the purpose of calculating the result of the round, the competitor’s result is converted this way:-

1000 X  ——–

where PW  is the best result in the round, and  PI  is the competitor’s result.

5.F.12.     Classification:  The sum of the competitor’s round scores will determine his position in the final classification. The lowest round score of each competitor will be discarded and the others added to obtain the final score which will determine his position in the final classification.
To avoid ties in the classification concerning the five best scores, “classification rounds” are flown until the ties are broken. If this is not possible, the result of the discarded round will determine each competitor’s position in the final classification.

5.F.13.     Organisation of the Contest: The competition must be held at a site which is suitable
5.F.14.     Changes:  Any changes in the flight and landing areas may be made only between flight rounds.

5.F.15.     Interruptions:  A round in progress must temporarily be interrupted if:-
a)    the wind force unintermittently is below 3 m/sec or more than 25 m/sec.
b)    the direction of the wind unintermittently deviates more than 45d from a line perpendicular to the main direction of the speed course.

A round in progress is to be cancelled if:-
a)   the interruption lasts more than thirty minutes;
b)    fewer than 50% of the competitors have been able to perform the task caused by marginal conditions. Without the condition “unintermittently” (i.e. 20 seconds) have been met and thus automatically caused reflights.
