Re: Broken Skytech pinion tooth (Q200)
Kevin Fortin <kfortin@...>
Jim,
I know about the motor mount mods that need to be done but haven't heard
about the "magbox" mods you mentioned. What's happening there?
Thanks for you time and I wish I had listened to you earlier (oops).

Kevin,
1. Thank Rich for all his help, send it back and try to get a refund.
Don't waste your time trying to make another Skytec work. I tried
that three times.
2. Buy a B&C, have Bruce Bainbridge upgrade the motor to a 320, no
charge(better for high compression)and install it.
3. Go fly!
The B&C starter has worked perfectly since the install. The
modification to the mag box was simple and the motor mount only
needed to have one corner cut off the pad. About 10 hours work, start
to stop.
As I've said before the B&C starter takes much less power to run it.
Hopefully I've put the starter issue behind me. You can do the same.
Sorry to hear of your troubles. I do understand!
Regards,
Jim P

3. I believe the real problem is Skytech's
centerline distance of the pinion/crankshaft gear set. In an effortto
loosen the tolerances in the manufacture of the starter, Skytechhas allowed
the pinion to get too far away from the main gear on thecrankshaft. This
results in an incredible force trying to separate the gears. Thisforce than
further deflects the shaft that holds the pinion, which leads toeven higher
forces on the gears, then ultimately to a broken tooth.the
