Hey John Bell, What radiator are you using?
Thanks,
Rick in Alaska


Hi Rick,
I will have one made after I get the exact dimensions from my airplane
installation after I set the location of the engine. I havent yet gotten
my radiator yet. I think I know the basic sizing I'll need, but I dont
know all the details. I should know by late this summer.

You don't need to get one made John. Just buy a two pass from Summit racing
or Jeggs. Worse comes to worse you can modify a single pass into a two pass.
What kind of airplane are you building John? For a 300 HP three rotor you
will need about 900 cubic inches with an average duct and a bit less
if you do a real good duct.

Mark Steitle is flying a three rotor and as far as I know it is cooling
down there OK in hot Texas.
