A 46FX is not nearly enough power for this ARF, I have had two of them. One with a YS63 and another with an Irvine 53 2-stroke. The 53 was not enough. 45FX needs 5 pounds max, the F40 is closer to 6 pounds.
I do not think he wants it to be a 3d machine but just to have good aerobatic capability
My understanding was that the guy was not looking to 3D it. Just sport fly it.
I agree totally if you are going to 3D it go with a stronger motor.
