RE: Timing off on a Saito 91 will?
Hi Richard: I run a 15x4 WIDE APC on my Satio 91 for 3D on a MOJO 60
What Extra are you flying and what does it weigh? What fuel and nitro % and most important you only talk about ground RPM, how does the engine prop combo fly? For full on 3D you want the biggest dia lowest pitch prop the engine will happly turn.
For lots of Satio info go to the glow engine form and search for "club satio" Post your question there.
I have not checked my RPM will be out Sunday I can check and post for you.
