Hi there Paul
I have just read your book , especially a big thank you on supplying the book, an excellent in depth read, I hope you have enjoyed your trip down under.

Just a quick question in regards to your defused idea for the rads mounted under the motor with the diffusers , was just wondering if I were to mount my radiators like this whether do you think there would be a need for exit defuses as I w planning on maybe mounting with the exits virtually flush with the lower cowl for no restrictions on exit gases, do you think the boundary layer would allow enough to get the air out or should modify with the Venetian style idea, sorry this is with the rv7

Cheers
Christian

Definitely go with the Venetian cowl flaps as closing them when you don't need max
cooling will reduce the cooling drag and keep the engine warm. You will save money in the
long run.
