Thanks Bax.

Some things I've learned the hard way:
I have new OS 40 La, breaking it in today.........
1st off, the prop came off twice, the nut was really....tite. Took off the spinner, problem solved.
2nd even on a new engine, you need to take the screws out and lock-tite them. Matter of fact I need to lock-tite every screw on this bird.
I know that someone is gonna say that the prop isn't balanced, but it is. I replaced the broken prop (cracked from it coming off) with a plastic prop (didn't wanna ruin anymore of my wood props)
it is balanced.
Got it all figured out though.

Joined AMA today and contacted local flying club, should start training soon. Was gonna learn on my own, but wife reminded me....of how much I have invested in this hobby.

Have this ARF going and building 3 kits. Love to build.
