giant scale rotary (Wankel) engine

[hagenaer]

Hi all,

I was wondering if this exists:
a rotary engine, also known as Wankel engine (for description visit freedom-motors.com), that is small/big enough to fit a giant scale helicopter (about 3 meters (120") rotor diameter) and produces about 5 HP.

The only Wankel on the market for our toys is made by OS, and it's about a 0.30 two-stroke equivalent. Way too small for your ten-foot rotor cone. However, if you just want the appearance check out the Erickson MC series, available in a 1.2ci and a 2.0ci version. www.ericksonmotors.com Pretty sure the 200 would run it if you kept it light, if you were willing to go a bit smaller you could use either. They do sound about the same as a Wankel, too. And not too many people could tell the difference in the appearance.
