My best guess is that that is a Cox TeeDee .020 engine.
Output of around 25,000 RPM.
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.
