get those #s for you.
Also, a friend has built and flown a couple of Mazdas and has his own gear
reduction that is pretty clever. I'm guessing though that he probably
wasn't pulling more than 140hp so hence the question... how wide of Gates
HTD belt to handle 200 hp at 6500 RPM (takeoff only)? Is there a better
option than the Gates? I'm most concerned with width since his reduction
has the width as one of the constraints.
One point of note... a while ago he ended up spinning his plane in due to a
rudder cable problem (I'm not sure exactly what happened) and his entire
tube and fabric plane was made of mild steel except for a few 4130 areas.
He ended up walking away from the crash and said that not a single piece of
the mild steel broke but that *all* the 4130 pieces did. Anyway, just
something I thought was interesting.
The crash broke the belt on his reduction but he said that up to that point
(with several hundred hours) his belt showed absolutely *no* signs of wear
(he said the the Gates factory reps told him to look for any "bumps" on the
backsides that would indicate the fibers were breaking down.)
Would be interested in info on belt replacements. Didn't someone mention a
"new" belt out with a herringbone pattern or something?

I have no experience with belts so I can't say. People generally ignor
the HP ratings in the belt engineering catalogs anyway. If you went by
those HP ratings nobody would ever use them. Perhaps someone else on
here can help. I would recommend cooling them however with a blast tube.
So it is a V6 STOL and therefore it is a tail
dragger so we don't have to worry about the nose gear. Correct?
