So it's been a really long time since I've messed with glow engines (been gas and e power) but I'm getting ready to start on a Great Planes Ultimate .40. I've also ordered a new OS .55AX and Bisson pitts muffler to keep the cowl looking nice. The engine will be mounted sideways. I also got an OS F plug for it because I know from personal experience that this plug makes a BIG difference in how well it runs. I was just curious to hear from guys who have run this very setup and if you had any insight/advice for me.

FWIW, I've run .55AX's before and I know they are great engines! If you've never run one on a Macs header and a Coke Can Pipe/Mousse Can Pipe you don't know what silly power is!!!
