Like described by airco, the flights in the high venue were very powerful climbs initially, then leveling off under the rafters. Imagine hitting rafters, repeatedly, at 100'! Only 2 got stuck, and we freed them with helium balloons.
I am happy to report that our testing at home scaled well to the 100' room. We tested with 1/5 rubber, generally 0.5g of rubber and a 2g stick, flying to 20' at home. This gave us an excellent starting point for the 100' ceiling.
Interestingly, the kids found different solutions to get to 10 minutes. The top flyer had very high pitch, with slow prop RPM and thick rubber. That is also the route I took. However, another kid had fairly low pitch, with higher RPM, and she was beating up the rafters. We kept cutting the rubber thinner and thinner, and she reached within a few seconds of the high pitch kid!
All of the kids used the SO log sheets that we have, and analyzed the data, changing one variable at a time. They progressed from 6-7 minutes to over 10 minutes throughout the weekend.
All of this translates directly to SO. The planes were lighter (3.1g), but the processes to improve are the same. It is amazing to see these planes go up like a rocket, then level out and float on the air.
