I have both motors but cant decide which to use I think the 91fx would be a bit more power but I tend to favor the 4 strokes. If anyone has experience flying with both engines (on the same plane) I would appreciate your opinion.
Tripower,
Your going to love this plane. Mine has a 2 stroke .61 Thunder Tiger Pro with a 14x4 wide prop. It flies great. Like Timcat says, It's not a speed plane. I have known guys who overpowered them and actully ripped the wings off. They even tell you that in the manual. Mine has plenty of power with the .61. It will pull the plane staight up with no problem. The 14x4W prop keeps it slow with gobs of torque. My friend has the same plane with a O.S. .91 on it. It also flies great, He can punch it staight up as soon as it leaves the ground. The plane is my most favorite to fly. It loves flying in the wind and will land like a balloon. In fact after a few landings with the UCANDO, you will need to be carefull landing your other planes. Most won't land as slow as the UCANDO.
I say put on the .91 and have fun.
