Go with what ya want but if you open up that 61 full bore on that cub, look for the wing to fly off or lots of flutter on the ailerons. Of course you can always cut back on the throttle once airborne and plenty of speed for takeoffs. You open up that 61 on takeoff and it'll be going so fast it'll be airborne before it even has a chance to go right or left on you down the runway! About 30 feet and it's airborne at full throttle! lol
That plane wasen't meant for speed. My OS 46 AX i have on my current cub has about all the speed I want without losing the wing.
Baloney - been there, done that, flew the snot out of mine with the OS 61SF. Flew violent aerobatics at full throttle, even with the extra 2 pounds of camcorder on board. I did (as I do with all my kit builds) use two servos on the ailerons, one centered in each panel. Used standard Futaba 148s with ball-bearing conversion tops. I've seen Goldberg Cubs flown with everything from bushing 40s to 91FXs, and 40 Surpasses to 120 Surpasses. The huge motors had to be shut down to land, but never a structural failure.
Seb23 - although many pilots earned their wings in full-scale Cubs, the models really aren't primary trainers. I'd recommend getting
http://www3.omnimodels.com/cgi-bin/w...I=TOWA1130&P=0 to start with and learn to fly while you are building the Cub. The radio and engine can move right from the trainer to the Cub when you are ready, and you have a much better chance of learning to fly and staying with this wonderful hobby. Use coupon number 44W36 and you'll save $10 on the plane. It'll be the best (and smartest) $109.99 you'll spend in this hobby.
