REFLECTOR: Ordering an MT Prop

[Dave Nelson]

I'll make one comment on this discussion.  I bought a MT prop for my
non-counterweighted IO-360 before the RPM restrictions were known.  It was a
great disapointment...

However, as a company, MT has been excellent to work with.  I've had two
motor problems with my electric prop.  Yes, it's true, I shouldn't have had
ANY problems, but read on.  The first time they immediately sent a
replacement motor, no questions asked.  The second time, they sent a
replacement motor so I could fly the airplane, and a new, upgraded motor
system - which they installed for me at the Oshkosh airshow.  During that
work, the engineer doing the install observed some minor cosmetic damage to
the prop - and enabled me to get the prop refinished - under warranty.

This is a company that stands behind their products.  I believe they'll
stand behind us in finding a solution to the RPM restrictions.
