Attached are some photos of the cowl mod and new diffuser mold …
haven’t flown since Dec 6; have to repaint cowling and install new
diffuser to radiator. Any suggestions for sealing to face of an aluminum
radiator?
I was thinking either marine-grade epoxy or blue RTV. Hope to be
flying again by mid January ‘09.
Merry Christmas to all you rotor-heads and best wishes for the
New year.

Thanks for that suggestion Lynn …
Activity: I’m moving my radiator air intake slightly
forward (about 3”) to get out of boundary layer and molding/making a
streamlined duct which can be 100% sealed to face of radiator; the rear iron air
purge line to expansion tank (3/8” hose with 3/32” drilled
restrictor insert) has been worked out. Will provide pictures of
cowling/ducting mods next week … expect to do layup tomorrow.

Jerry,
things are real quiet on your part, how is your project coming?? We do
miss your activity like when you where on the Tailwind Activities. My
project is receiving the finishing touches and will be ready to go when the
snow clears in the spring. It is looking like I don't have enough prop
(68 x 72) on the Rotary, will need to get it out of the garage after the new
year and run it some more with the tach that Bob White put together for me.

The rotary has ports open to the outside all of the
time. Humid air can enter the engine as it goes through heating and cooling
each day. In a barn, in a hanger, even a heated shop. I use motor oil in the
intake and turn over the engine a complete cycle, (three crank
revolutions) and tape the exhaust pipe shut. Turn over three revs monthly when
out of service.
More of them have died sitting still than running.
