Enjoyed your note on working with the .61 Evelotion...I have a friend who does mechanical work and annuals on full sized planes. I'm trying to costantly fly a J-3 cub...the .61 was way over powering the plane, switched to a O.S. .46 with a 3 bladed prop...much better control, especially with the tork problems and engine performance. He listens to my sad stories on engine performance, tips rolls. 3D's, and underperforming rudder servo tork on take-offs with my cub. He has helped a lot with suggestions on tank location, engine venting, running rich and lean and a good lecture on tork. I guess the mechanics of flying R/C vs. the full scale is... we are just smaller.
