Well I have the 17-10 and used it sucessfully in the last pattern plane. we will see where the rpm's end up with the new carb and the pump,
and with the addition of a real pipe (using the stock carb with it's need for lots of tank pressure I used a .61 sized quiet pipe for a muffler.
I will be replacing it with a 1.40 sized pipe to see if there is a power increase as well. )
Just going to the perry carb and pump made a HUGE differance and the engine was running good before. I like the ST's and the price, well
lets just say thats a big help on the budget so I can run Digitals on both Icepoints.
