RE: Engine for Funtana X50
I agree with skyzkings response on the use of 2 strokes, and as I stated, 4 stroke is a CHOICE and in some cases even a challenge. My Funtana 50 flys superbly on the 45 Super Tiger swinging an APC 11X5 and I'm going to try a 12.5X4. As I mentioned earlier, again 3D is a CHOICE, not a "must do!"
