I have been flying rc planes for a few years and I have a .60 size 540 edge that I have had since 05. It is running a OS .61 2 stroke. I have played around with inverted flight, knife edges etc. I have not mastered knife edges nor hovering. Do I need a more powerful engine to accomplish these manuevers? Also what control surfaces need to be executed in order to do this...i.e. full left or right rudder for knife edges correct and compensates some elevator?
Thanks
