Since there is more interest in the 20B than expected,  we will be offering
a 20B overhaul kit in addition to the currently available 13B kits.  Will
put it on our website as soon as it's ready.

Paul, has anyone actually used the TES Oil seal O-rings in an operating
engine (car or airplane) yet?  They look good on paper but I am hesitant to
offer them until they have actually been tried.  I'm working witrh someone
who is planning on using them but engine run is still months away.

The Viton O-rings now included in our kits are more heat resistant than
stock and have been well tested.  The TES version could be even better so
will include them when tested.

Chuck has a set but has not installed his new engine yet. I would not
worry about it at all. I see absolutely no show stoppers on this. Nothing
but advantages. Unlike the stock oil O-rings they won't go away if
you overheat the oil.

Having said that and be that as it may it is no big deal if they don't
work perfectly. So it leaks a bit of oil on start up. I ran my 76 Cosmo for
years (10 or more) with a big cloud of oil smoke on start up. No worse
than a radial engine.

Tracy,

Some of us will want 1/2 13B kits for single rotors, also. Maybe if the single
rotor buyers = 20B buyers you can come out even (:>}. Or maybe you should just
sell them as per rotor sets.
