Finished and Flew the Airtech Fitness

After a nearly disastrous start to my Airtech Fitness’s life I got the maiden flight out of the way and found the plane an excellent flyer.

 

Fitness ready to go

The disaster nearly happened on my first maiden voyage attempt at Big Bay. The wind was coming in at about 20 and I felt it would be a good first flight day. Plenty of lift! So, I range checked it and tossed it off the hill. Got about 70 feet. Looks good! In the next few seconds I had visions of the Wizard going in the lake as the Fitness was not responding to control inputs and threatening to follow suit. Wait, there, it turned back towards the hill. Oh, no input, not responding and it is heading over my head! More mashing of the controls and the plane dives into the ground going 40 or 50 mph. I got that sick feeling you get when a plane crashes and it seems like it will be toast.

Mirko’s Airtech Fitness

Mirko Bodul sent in this review on his Airtech Fitness, a French made 2-meter slope or thermal plane.

I received my FITNESS early last March and have been flying it since the end of March. A very easy plane to build and fly with no bad habits; ailerons, elevator, and rudder are the control surfaces. Stalls are nothing more than the classic “mush;” no nasty spin on the wingtip or other nerve racking behavior. The plane accelerates well in dives, and “zooms” very well for height recovery as do most Airtech planes.

This fast, 2-meter, thin winged plane flies in very light lift or in howling 35 mph winds – with no ballast. I don’t bother with ballast. I get irritated if my unballasted plane does not fly in all conditions. This plane has never irritated me. For those of you who must absolutely load up with dead weight, the plans advise no more than 500 grams of ballast, that is to say, a little over a pound. The plane comes in at about 35 ounces overall weight. Airtech, the manufacturer of this fine kit, recommends using 1.5 degrees of down aileron (flaperon) in light lift to help while flying in thermals. The S7012 airfoil is exceptionally efficient in light lift.
