RE: Overloading an engine

All summer I've been flying my H9 Corsair with an RCV-90SP and a 16x11 3-blade prop. The engine likes this prop and I can get a peak 5400 RPM (2:1 gear reduction built into the engine).

I finally tried over-propping my RCV-90SP engine. The motivation is to try my custom made 3-blade hub with 18" blades.

Here's the video of my attempt:

The question again is... If I make sure the engine does not over heat, is there any long term negative effects of over propping an engine? I can really get used to flying with that nice big prop.

Thanks,
Juice
