I fly a sea dancer with a magnum 91 4 stroke. I am not a 3D pilot. I just putter around. I also have a dehavilland Beaver on floats 75 ASP. So that is my extent on larger engines. I do a lot of scratch building. Mostly in the 46 to 52 range. Have been using HiTec 322 servos on most of them. I have some Planes that have the pull-pull system. Just not sure the servos that I have been using may be enought. Thanks for the concern. My Dehavilland Beaver has flaps and that is why I was wondering about putting flaps on this one. Does not show it in the plans.

The Dehavilland Beaver is the one shown on the left of this message.
