We do a lot of small things and tricks. Smaller pipe runs cooler, cut the pipe 1" inside the fuselage to get a venturi effect etc etc.

Double walled pipe are not needed. I think even the aluminum tape are not needed really. It's great for gas start engines in case of a gas fire. If a kero start engine burns it's all over anyway LOL.

Yeah, the 80mm Avanti is getting heavy if you go X45 or K30/K45G3. With Kolibri it's fine though. You need to size up to get things comfortable, what is best is always up to you but I would not call...
