I made it to about 400 flights before getting the rear bearing replaced in one of my170 DZ's. Probably should have stopped at 350.

Hey Keith, you may be interested to know that I finally have a 2M electric bird almost ready to go.Might be ready tofly tomorrow if Ican stay awake a few more hours. I'm slow rolling my transition to coal powered pattern. I'll wear all the metal off the cylinder linings of my 5 170's before Ibuy switch over toe-power100%!I just likethe 4C sound and smoke trail too much to let it go all at once. And to think, just 2 years ago all I flew was 2C glow.
