Thats one of the reasons why i like to break my engine on the plane. granted it does a little more effort to bring the stuff out. It also gives me an idea on the best way to start it etc. I now know that i gotta loctite those screws and bolts.. I may take the prop off and check the balance again but, i dont think thats it. I spent an hour on that god for saking prop to balance out. Ill wait and see what happends when i further run the motor.
I kinda like the carbon fiber rod idea. May have to try that out some time. Telling ya trying to solder the joints for the flying wires was a bear. But looks very nice.
