Hello Everyone.

Im happy as I have been able to have much more power out of my 33cc Mitsubishi conversion taking out the muffler and making my plane much more fun to fly

Anyhow I dont have such a stable idle and transition compared to the one I have when I have the muffler on.

Does the muffler have an effect on carburation? I thought not as it was not pressurizing the tank but seems Im wrong.

Generals of my engine are

- Mitsubishi TLE 33cc
- Original muffler gutted with 2 outlet tubes - Now flying without muffler and get arround 500 RPM more
- DLE 30 cc carb on it (Haven´t opened the manifold yet)
- Spinning a 18x6 Turnigy prop at 7,000 RPM (flying at 2,240 meters over the sea level)

Thanks everyone.
