They don't fly supersonic so my guess is less than 400 miles, or 2.35 mpg. That's with a stock engine. I think his new one is more fuel efficient.Holy Jet Fighter Batman!!!
Mike, Do you notify everyone in the state before you fly that thing? I do not know the protocol but would think one wrong move and somebody wants to have target practice with you. Any good stories of the USAF coming to greet you?
170 gallons an hour. How far will that get you?
Damn dude!!! :eek you got to be the coolest cat on this site :bowView attachment 27903
My “project” doing a re-engine on my L39 is almost complete! Its been 17 months. Other than the physical engine mounts, the inlet ducting, exhaust/bypass ducting, pneumatics, hydraulics, electrical, removal of APU, linkages, instrumentation, computers, weight/balance, FAA....... its really been pretty straight forward... First flights were last week – and the results look very promising!
We took the Russian engine out (Ivchenko AI25-TL) and replaced it with an American engine (Garrett TFE-731). Net result is the plane is lighter, more thrust, (much) better throttle response (6 seconds vs. 12 second spool up) – and better fuel consumption. Access to parts / expertise for the engine also is greatly improved.
Finishing flight testing, and then “Natasha” can come home to Minnesota!!
