hi all,

I have recently acquired a usd CY models La-7, fitted with a little-used Saito FG-84R3. The model needs a reasonable amount of refurbishment but it will be good when it's done! I've recently finished the engine installation to the point where I could test run the engine - runs really well, but the prop I have for it (a biela 3 blade 22x10) is a little light, and the engine is over-revving slightly at 6,600rpm. So I'd like to load it up a bit more, I think either the 23x10 3 blade or the 22x12 3 blade will be about right. I am leaning towards the 22x12 3 blade for a model like this - any thoughts from those who have flown models like this?

thanks!

James
