Coming to ask advice from the veterans as this is an unusual problem. My gym that I test in is 26' but rafters run along the entire ceiling making the clear airspace about 22'. In addition to this, the basketball hoops hang lower than this, about 20' up and there's a retractable divider curtain that also hangs low and inconveniently bisects my flight path.
A few details on my plane: 5% camber on the ribs, the OA length is a little less than 2' and the surface area for all the lifting surfaces are maxed out. I'm using .08" rubber from Dave Ziegler and the flaring ikara propeller cut to this year's rules. I generally go up to 1200-1300 winds, and have found the launch torque to be about .67 in/oz.
My problem is that the climb is fantastic but doesn't level off when I reach the top. It seems as though i've built something potentially reaching 30' but that has to fly in ~24' ceilings. I've had problems getting planes stuck both during testing and competition. So far what i've tried is decreasing the decalage but the plane starts to stall or doesn't climb, so i've stopped trying that. The only other idea I has was thinner rubber that would burn off torque quicker. .0625" doesn't produce enough torque for sustained periods, so I ordered .07" and .075" from Dave. Do any of you veteran flyers have any ideas if that will work or on how to make the ascent more gradual?
