OS70 FS max and idle rpm ?

I have the os70 FS running a 13x6 MA prop and it cranks out max 9000 rpm without Nitro and it idles at about 2400rpm

Can you share whats the best Rpm you get and what its idle rpm ?
Thanks
KJ

Your engine is perfectly normal with these rpm figures.

I have a 70Surpass with a 12.5x6" Graupner Nylon at 10'000 rpm. 5% nitro fuel.
