Hi Guys,

I scratch built a big 12 foot long T-38 and it fly's pretty nice with EDF power but is a little under powered. I was considering converting it to turbine. The plane is built entirely out of foam. AUW is 41 pounds

The plan would be to have a custom double wall bifurcated pipe made but my main concern would be protecting the internal foam structures from heat and was wondering if anyone knew what the average internal fuselage temperature got to on inside the fuselage of a turbine jet in the vicinity of the turbine.

Thanks in advance

Andy
