Pipe cooling inside the cowl

[MikeP]

I am putting together a Whiplash sport 40 and the pipe is inside the cowl. I would like to know how aggressive I need to be with air flow through the hull.

Some thoughts are:

Some air flow is good enough.

Need good air flow.

Need all the air flow you can get because it will still overheat.

A larger "exit" than "entry" will give you good airflow

a hot pipe works better than a cold pipe. unless you are burning things up let it get hot. geno

My Dave Frank Sport 40 is completely enclosed. Currently there are two 3/8" holes on the cowl. They are old and current antenna holes.

Thanks,

It sounds like overheating is not a problem and a hot pipe is good.

Mike, don't worry about it. Put a couple of holes in the cowl. You will be ok. I have been following your build. Your skills are VERY impressive!

OK I have to ask where did the rudder come from and is it of Delrin material? Nice pics.

The black rudder is molded plastic\carbon from DPI. I get them from Climate Models.
