Default Congratulations for a fine engine, RCV.

I installed your 120SP in my 13.4 lb. Top Flite .60 size Corsair last September. It turns an 18" 3 blade custom prop with the adjustable pitch set at 12". I had a friend put it up for the first time last Saturday. (I don't think that I'm accomplished enough to fly it just yet.) Let me just say I was amazed. I was expecting my overstuffed bird to fly like a pig. That big engine pulled it into the air with ease and my friend had to throttle back to half throttle in order to slow it down enough to set the trims. I've never seen an engine of this size with so much "pull." Extremely large loops are no problem for this engine and I certainly didn't expect my very heavy airplane to move with such speed. I've read on these forums that these engines don't give one alot of speed. Well, this one flies that Corsair faster than I want to take it! During the warmup I asked my friend if he thought it had enough thrust. He just smiled and nodded.

For those who are worried that this engine can't fly their big plane with authority, don't think twice about it. It will. It's made a believer out of me.

Thanks again for one very powerful engine,
Joe

Hi Joe,


do you have any rpm values for your prop?

Thank you
Andi

Hi, Joe:
What kind of muffler are you using?
Are you flying with this propeller on the picture?
Congratulations for the beautiful plane.

Andi, I got 4300-4400 rpm with that prop in the picture.

Leonardo, I made my own muffler out of steel (couldn't keep the aluminum one on). I am flying it with the prop in the picture. That big, beautiful prop is Juice's creation. It's a scaled-down version of a SoloProp hub and uses SoloProp Blades.
