Bob,
Great to see you posting again....
You wanna see something powered just right, how about my now deseased Extreme Flight 78" Extra. This 30cc model was a test bed for 30cc engines, 38 cc engine, 40 cc and finally a DLE 55, all piped. The best and scariest combo was the DLE55 on pipe. 12 pound airplane with about 35 pounds of thrust. Just right!!!
BTW the EF Xtra died from a bad Spektrum 9ch RX that was supposed to be full range. Not!!
The next best power to burn combo is a Neu F3A geared motor driving a contra drive on a 9.89 gear ratio and 10 cells. The props are 21x22 and 20x21, front and back. This 11 pound model's expensive props (about $200 each) simply are not allowed to spool up with the plane on the ground. So the typical take off is full up elevator and throttle up when ready. It blasts off in about 6 inches....Just Right!!!!
If you think I'm bragging, You're Right!!!! LOL
