RE: U-Can-Do 3d 46?
No, shown in the pic is an OS-72 (no pump but it runs like it has a pump!.. no kiddin)
Plenty of power too, running YS 20/20 fuel (I love oil) spinning an APC 15x5.5 prop, 1/2+ throttle hovers.
I have a YS-63 and was going to put it in the airframe which I am now converting to electric.
Supposedly, the YS-63 packs a little more punch.
