Enkei,

What are the odds ... I have 11 props in my flight box you picked the one I don't have ....

Anyone else have a OSFX 25 with a different prop that I might have to compare with?

I'll start mine up tonight and post the results later ...

Cheers!

Hi IMCub,

What sizes do you have? I flew it with a small size pattern plane. I have tried an APC 9x5 before, but I prefer 9x6 because it hauls the plane much better.

ciao

Hi Enkei,

I have 9x5's graupners and APC's and Master Airscrew in 10x everything ...

It was running over 13,000 this evening ... but the engine is still breaking in and I didn't lean it out too much.

I'll stop by my LHS tomorrow to pick up some APC props 9x5 and 9x6.

The OSFX 25 is so much quieter than the 46's I've been using ... so I wasn't sure it was really coming up to speed. If I'm anything close to 13,000 with the APC 9x6 I'll be satsified that everything is as it should be.

Cheers,

Dave

Hi.
I donīt have rpm figures but I have been running with a MA 9-6 from 4 years to now. I can say that this is one of the best engines I have ever had. Very strong for itīs size and perfect transitions. I never had a deadstick landing.

Good luck.
Daniel Maia
