RE: Engine for 60 Ultra stick?
I have the ultra stik with the magnum 91. It has all the power you could want. Unlimited vertical, very fast and will pull out of a hover without a single problem. Just make sure you put the servos in the tail and you will have no balance problems. Also, put the battery in the back of the radio compartment. That should get you at manufacturer suggested CG to start. Then as you fly it more, you can make an hatch and put the battery in the tail.
Also, get a larger tank for that motor. I suggest a 16 oz.
