Neal,

Here's a picture of a Kwik Fly 3 from the Kwik Fly Mk 3 build thread.
They look like almost the same plane. I checked a old Lanier catalog
and could not find anything that looks like your plane. I may have an
old Dee Bee catalog, I have to dig the kit out to check.

If you plan to fly without a muffler, there's no way known to man (not
to me anyway) to keep the oil out of this type of plane. Once the oil
finds it's way in (and it will), there no way to get it out. Something to
think about and JMHO.
