Looks like a nice shaped diffuser.  I used some heavy duty aircraft rubber I had laying around.  It’s glued to the edge of the  fiberglass duct and fits snuggly against the outer edge of the front of the core.  When I pull up the bottom part of the cowl to install it, this lifts the duct into place on the front of the oil cooler the rubber protects the core and seals against it.  That way I don’t have to keep applying RTV each time I take off the cowl.  Seems to work, no signs of leaks – but then air leaks don’t necessarily leave nice easy to spot trails.

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.  Farmer John

 

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.
