Default RE: Spot On 50 Build log.
I have 2 OS-55's and they both ran poorly at mid throttle untill I leaned the low speed needle about 1/2 turn. After you get the high speed set then adjust the low speed till the engine runs smoothly at low and mid throttle. I have seen this on at least five other OS-55's.

I am actually using a 12/6 on the Spot On and 11x7 on the other plane. Both APC props.

Sorry about the crash[&o]. At $149.00 it's probably cheaper to replace than rebuild[]? It's a great flying plane.

Good luck.
