Is it mandatory to mount Gas Engines Inverted?
Hi there all,
As I'm new to gassers and my plane is in a process of getting there to hit the flying field. My plane is Yak 54 120 and DLE20 is the motor. Is it mandatory to mount the Gas engines inverted? I've seen they are on 90 degrees angle sideways as well here on some thread. Is it due to muffler or is it possible we can mount those engines 90 straight or would it make a difference in engine's performance?
I've been told and read that mounting glow engines inverted either 2 or 4 stroke changes engine's behavior a lot?
I just wanna know your experiences.
Thanks and happy flying[8D]
