To all you experienced pilots out there...

I am looking for some advice regarding my plan to use fibre glass ducts I have made to cool my 35cc DLE motor?

I have made ducts that will redirect the airflow directly onto the cylinder head of the 35cc DLE the configuration of the cowl has three air inlets the bottom is basically right in front of the cylinder, but the two other air intakes are allowing air to move past the engine. So I have made these ducts that will direct the air right onto the cylinder head from each side.
I have read a few posts were the 1 to 3 rule has been mentioned as well the standard outlet looks a bit small to me.


My question is would this work and provide enough cooling? this is my first gas plane build and would like to know what other suggestions are out there?


Kind Regards
