I built a fiberglass duct into my cowl that my secondary radiator sits in.  There is a bit more headache when the cowl needs to be removed, but I have the pain minimized at this point.  The cowl on a delta generates lift, so in my situation, mounting the radiator in the cowl shortens a load path.

Wish I could do that, but my mount is nowhere near the front of the motor. I will make sure that there's room to move between the cooler assembly & the cowl, though.

Thanks,

Charlie

Charlie,  

Everything moves, so my recommendation is to design to allow for movement.  Initially, I had my oil cooler attached to the re-drive adapter plate with bolts and rubber grommets.  The grommets took a beating as did the bolts and flanges.  A year ago I re-designed the whole oil cooler assembly and isolated it from the engine by securing it to the motor mount.  This approach has worked much better and I plan on keeping it as is.

I've started design/fabrication/redesign of my oil cooler mount/diffuser. Just as I had a 'final' answer on the mount & was contemplating the diffuser, it occurred to me that I didn't have any shock mount provisions for the heat exchanger. For those who have been flying for a while, have any of you hard mounted the cooler to its support structure? As the photo shows, the primary mount is direct to the reduction drive plate. I would simply add the shock mounts, but if I use this particular cooler (a CX Racing 30 row unit like the one on Tracy's 20B), I won't have any room. I do have the option of buying a 25 row or using the 19 row I already have on hand, but I'd rather have a bit too much capacity & throttle the exit air than start with too little & have to rebuild everything.

Thanks,

Charlie
