High Angst is my first larger sloper. The 4.5 lb weight (16 oz/ft2) was a little disconcerting but I had nothing to fear. It flies as if on rails and is super stable. Mirko has always extolled the virtues of larger planes and it is easy to see where his enthusiasm comes from. Yes, Renolds Number does exist!
The severely tapered wing and only 10% stab area spelled “tip stall” to me. I set the CG at 25% MAC as a starting point and have since moved it back to 30%. I used an aluminum spinner that did not have prop cutouts for the nose. I made a clay impression of the inside of the spinner then cast a mold in plaster of Paris, using the clay as a pattern. When the plaster was hard, I poured lead in the mold. I was afraid that pouring lead in the spinner might distort it. This worked great.
Flying is different from the SH-50. I have to think ahead a little more. The SH-50 can roll or loop in impulse if you have some speed. The High Angst requires a little forethought as its inertia makes it a little slower to react. I have increased aileron throws to liven it up. The fast swooping flight with great E retention is its forte.
On the first landing, I overshot the approach and flew it between tree branches without a touch. Lucky! Spoilerons are effective for slowing down. I recommend them on all slopers that do not have flaps.
