RE: another darn ryobi post (ryobi performance modification, analysis and comparison)
I am sorry and dont take this wrong but I just dont see why you would want to use glow fuel in a gas engine. If thats what you want there are plenty of good glow engines on the market that are pretty cheap. To me the point of this conversion is to have a gas engine and not have to buy the expensive glow fuel. i will be interested to see what your apc runs for rpm. i am using a dynathrust as i really dont like the apc props.
Anyhow I think that sounds about right on the weight. The biggest gain on going to the electronic ignition will be a power gain and being able to hand start and weight savings if any is achieved will be a bonus.
