Just ran the engine for the first time with the Iron Bay regulator. I have a Saito 100, fuel tank is on the CG. before the regulator I had the highspeed needle open 1 3/4, Now it's open about 4 turns. Is this normal? Seems to run better, I haven't adjusted the low end yet, it's very close where it was.
Also, for you guys that have the fuel tank on the CG. how many inches is your CG form the leading edge?

one last question, is there anyway to make this thing knife edge nicer?
