This is what I am thinking too!! These type planes(Yankee Twister, Stick-it, Smith Special) were designed for limbo, spot landing, and Roops events and were not intended to go fast... just to be quick at the maneuvers and get on the ground. That's why I am wondering if a 4c would be as good or better.

30 or Saito 40 would be the right size/weight I believe. If you run 30% nitro with a large prop it might work for you (but thats a guess).
I would like to take this opportunity to discuss the charicteristics of a piped 2c. Doesn't putting a pipe on a 2c engine make the throttle transition sluggish? To where a 4c has better over all transition authority? Isn't that what 3D planes need? Not the blistering high speed's & horse power sluggishly built up from the supercharged effect of a pipe on a 2c, but the torque available at any position of the left stick that 4c's offer? I could be wrong here because alot of people use the piped 2c engine, I was just wondering what other people thought.
I realize that a hot 2c setup is probably what Ohyeah need's here (I don't know about a pipe though) but I was talking about the next few sizes up where you could get a supercharged 4c in place of a piped 2c. Does anybody know of a supercharger system designed for the 30-40 size 4c's?
