Most engines actually run at 600-1000Celcius. I very well know the display might say 500C while the engine glows white hot!! Does not compute. I did testing of this too and Jetcat was retracting...

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.

It's a common misunderstanding that turbines are hot. They...

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...

Yes, SS3 and no it does not work very well. You need to be lucky and do long sweeping passes such as the landing. SS does not seem to be in business any more, no FW updates for a year.
