Hi to all. I am considering a gas engine for a future plane that is weight sensitive (against manufacturers recommendation). By now you probably know is the DP Edge 540

Anyhow, could somebody help me with accurate weight including ignition/muffler for the following engines, because I have tried to gather info from the manufacturers websites but was not able to determine if weight listed are with/without ignition and muffler...in other words, want to compare apples to apples.

DA 50
BME 50
ZDZ 50
Brisson 2.4 and 3.2

My other option was using glow OS 1.60 or Moki 1.8 but I would like to try gas.

Thanks
