I have seen a throttled version of that engine.
Cox did once upon a time make a free flight heli with a Peewee .020 for power, It had a 4 blade rotor of around 16 inch dia. The Peewee had a lot less power than the Teedee.

This might actually be feasible.

I think I had one of those, it went up.....ran out of fuel and came down. That was in the 60's as I recall. It's getting harder and harder remembering back that far.
