Looking for advice---------------
Welcome to the Evolution of Flight.
Your two 61's may not be the best motors for a Fun Fly or 3D plane. That and all the current Profiles are 40 size.
However, the OS 91 you have is the good one. 91 FS or FSR are GREAT MOTORS. Wish they still made those versions.
Best bet, using your existing motors, is the OS 91. Put that motor in a Great Planes, U-Can-Do-3D. That is a sweet set up. The plane flies like a baby, slow it down to walking speed, do all types of crazy stuff, KE from horizon to horizon and down right the easiest plane I have hovered with the exception of a 40% Extra.
Allot has changed in 10 years. We have better equipment today, faster servos, better running motors, more prop selections, better batteries and more airplanes.
