I have both the U-Can-Do and the Yak. Got the U-Can-Do first and loved it. This plan really builds your confidence, as most crashes only take a few minutes with a hot glue gun. I've learned all the 3D maneuvers with it and even taught my 7 yr old to fly with it. Since I loved it so much, I just got the Yak and Wow. Maybe because it's just new and not glued back together a dozen times or designed better, but the yak flies knife edge and inverted harrier better and does real tight snap rolls. The only shortcomings I am aware of is that if you strike the ground with any throttle at all you have to replace the spear gear ($3.50, properly 8 of them over the last year) and the fact that the Li pols really get hot. The new balanced packs have better venting and appear not to get as warm. I have a garage full of gas planes and these electrics have become my favorite to fly, especially since you can fly them anywhere. One final drawback is that the fun of flying these planes diminishes in winds over 10 to 12 mph, although I've flown them in more. When you set up the plan, set high rates for as much as you can get with about 40% expo and you will have a blast.
