FMS Piper PA-18 Super Cub Motor Cooling Modification

This is Fuselage front part modification for FMS Piper PA-18 newly released Super Cub.
In first couple of flights I realized that the motor is overheating.
The air outlet behind the motor was getting blocked by the battery pack especially when I was using bigger battery for FPV flight. So I decided to remove the dummy muffler and fix a 3D printed exhaust pipe as air outlet. It helped a lot.

Here is the printing video:

I used Filatech Black PLA 1.75mm
