A question for Keith Lawes:

First off... I think it's great to have the inventor of RCV technology frequent these forums. Thank you.

I have an RCV 90SP. I am putting a 3-blade 18x10 prop on it. I know that prop is too big, and it's evident in the 4400 RPM maximum at full throttle. The question is... Is that bad for the engine? I've flown about half a dozen times with this prop and I like it. It still has more than enough power to fly my H9 Corsair.

Here's a video of the first time I tried it...

Can you also comment on how it will affect the longevity of the engine if I keep over-propping it like this?

Thanks,
Josh
