The Funky is a great plane I have one myself. Great for 3D and easy to land. I have a TT pro 46 in mine and it flies great but doesnt have enough power to pull out of a torque roll. I have seen them with a 70 sized 4 stroke and it is a great match. Not super overpowered but a great flyer and plenty of torque for 3D.

Standard servos are fine but I think the might mini's would be a great match since the Funky takes 6 servos. Especially with a 6 volt pack the mighty mini's would give great performance and save on weight. The manual recomends 2 servos for the elevator although I think you would do fine with one.

The instructions on the Funky leave a bit to be desired. If you have any questions PM me and I will help anyway I can.

Also, I would recomend reinforcing the landing gear plate if you fly off of grass.
