Good fuselage for RC Zenoah format. For PUH, bad news.

You have this PUH motor already on the fuselage so, several things to take into consideration:

1. Hotter place is the muffler because the 2T combustion finished there. The bigger the muffler or pipe, the better.
You need to isolated this area.

2. If you put fans on board, the key is to handle all this air to the bottom.
Separate fans for muffler.

3. No matter how many fans you put inside, the PUH motor is going to run real hot!
So, your concern is electronics and all plastics stuff you have there.

4. Isolate the fuselage with some sort of isolating tape.

5. "The pot" must be isolated or separated from boom. So, no hot air may flow thru the boom.

6. No fresh air is coming from rotor so, fresh air must be taken from both sides of "the pot".
