The below pics are of a DA in a WH Extra. I have experience overheating thus having the motor quit several times. The motor is currently at the factory being serviced.
I'm going to expose more of the cylinder and make a baffle/dam just in front of the exhaust tubes.
Can anyone give their estimate by looking at the pics as to whether on not the present cowl cut outs were suffcient to provide adequit cooling?
I also plan on blocking off inlet areas around the propeller. Is their any reason I should not do this?
Any other areas of this cowl I should modify?
This discussion has been very informative.
