Yep a 24x8-10 should do the trick. But also remember it also depends on the plane you put it in. Example for the G62 a 23x8 is the sweet prop for that engine with the mag. I found it pulled the Zirolli Stuka with authority but the same engine in the Meister 109 it was a 22 x10. So do some testing on the bench just to see the numbers you get. The engine may be still strong or it could be weak. Try to get to between 6800 - 7200 just to find out what the engine has in it. If it is not getting to 6800 with a 24x10 then you will have to prop accordingly.
