Do you have enough access room to drain oil without dropping lower cowl? I do put a high priority on making almost everything FWF in an alternative engine installation easy to inspect. With a unique installation you never know where the trouble spots might be.

I still don't think it will be a problem, because I have such wide open= access to the engine with the hood open. =A0It'll be just like a fende= r mounted component in a car. =A0The duct will also make the cowling stiffe= r. =A0 The nose provides a portion of lift in the Delta, so mounting a radi= ator there will provide for an extremely short load path.

Basically, I'm looking for a good reason* not to use the cowl as a moun= ting point.


*"We've always done it that way" is not considered a reason f= or this discussion.
