Well, i need some help figuring out these Gas engines. i'm new to them and have read so many different opinions on them.
First off, i'm planning on installing it in a CB Sukhoi Kit 72" version.(not quite done, but getting to the engine install very soon) i'm going with gas in this mainly because of cost of fuel, amount of fuel consumed versus the glow and clean up. i know this engine won't have as much power as a Saito 150 but i don't do any 3D flying, just basic aerobatic flying.
Do these Evo engines come with a muffler? engine mount? and is a 5cell ignition battery needed or a 4cell?

thanks guys for any info on helping me out!
