Fellows...I just picked up a very nice OS Wankel, very first model,
that someone "donated' to me...it is, however, missing the muffler.
This first version has a small round stack coming out for the muffler
to attach to...and the muffler clamps on to this stack.... Naturally,
Great Planes (OS franchise) no longer has this muffler.... Does
anyone out there have one they can spare?? I'd like to fly this in a
plane I have that will handle it nicely.
Hate to spoil your fun, but you may not think it has much noise.
That's only what you hear! Unfortunately they have a high level of
high frequency noise that is above most of our hearing range. If you
allow yourself to be exposed to this for any length of time (like 30
minutes or more) you will have a splitting headache later that day.
Furthermore it will contribute to hearing loss later on. I had to
learn this the hard way, just thought I'd alert all here.
