Sukhoi SU-26

First setup that flied was Speed400/6V with 1.85:1 gearbox (with 9x5 aeronaut folding prop). Fly time was about 2:30min with full throttle (8xSanyo 500AR).

Next I bought Hacker B20-15L with gearbox 4:1. AMAZING ! I knew that B20 is good motor but so good ! Su26 flies well even half throttle and there is no more takeoff problem. Fly times are about 4min (8x500AR), 4min30sec (8x600AE), 7min (8x1100AAU) and 2min45sec (10x500AR POWER !!)
