RE: U-Can-Do 3d 46?

Sure, buy the UCD .46 and you'll have a lot of happy flights. It won't be the best engine to pull out of a hover, but that is not the only manuever in the world. You would enjoy the UCD .46, The Twist or the Magic Extra with a .50SX. I would go for the UCD .46 as I have all three. If you like to fly precision type manuevers the .50 SX would do well in a .46 Kaos.
