Just quiet I guess.

For filler, I can offer that I've been in the shop working on my oil cooler diffuser, sanding, smoothing in microlight, sanding, painting. You all know the drill. It's hard to spread filler smoothly on the inside of the duct where there isn't really any room for my hand, let alone a spreader, or later a sanding block!

I've had good test runs since I bit the bullet and committed my time to making quality scoop and diffuser assemblies. I just hope they work as well when I continue to test @ higher power setting, and eventually fly it!

Tracy; when you refered to 'roof ridge material' as applied to the inside of the cooler diffuser? did you mean the aluminum sheet with small louvers? When I blow sanding dust out thru the cooler and duct in assembly, using compressed air, most of the dust seems to pass out the aft end of the cooler. I know microlite filler dust is heavier than air, but I think it would be a fair representation  of airflow when propelled with the air nozzle. So I'm taking what I understand you to have said, and may try to slow down the air at the back so the air flow will be more evenly distributed thru the oil cooler.

I made a more pronounced ramp in the radiator duct after reading about it in this forum, but I had already made the oil cooler diffuser. I might yet carve out the back and build in that ramp!! but for now I would like to know what that material is???
