closetguy thanks that what i was looking for.
nitro wing you still dont understand the question. i know all about what your talking about on props and how different ones can do better or worse on different planes,engines and even rpm's. i know max ground thrust doesnt mean crap. I already know what your talking about. I want to know if the engine I have is running the same as most other Moki/Mark 2.10's out there. Wanted to see if I need to re ring it or not kind of thing.
