paul   my name is paul brannon. lou rubin & i have
been talking to some off the guys on the east coast
aboat the prop butch diaz has built. we are very
interested in it. they say it has not been ground
tested so it shouldn't be put on a plane. we are
offering to test it. we have an extra motor in the
shop & tracy has an old reduction drive. we are
looking for butches phone # so we can find out if he
is coming to sun-n-fun and bringing the prop. any help
would be appreciated.   paul     fpbjr2001@yahoo.com

I'll send this to Butch PRIVATE email.

You need to modify your test stand so it rocks back and fourth
at a 67 degree per second rate to adequately test a prop for
gyro bending loads. This can be done by mounting the test stand
on a trailer and moving the tongue up and down.
