Sorry for not seeing this earlier, I was hanging out as Fresno Jets all weekend. Smitty is right in that it only uses one valve and comes with a LiMn battery. The ECU is pre-programed for A123's. All the evojet engines are internal Kero start and they all use an automotive 12v Kero burner....you may even find them on your favorite German diesel imports.

As far as the service and support, they carry a five year warranty and have 25 hour service intervals. The first 25 hour service is done here in the U.S., and the 50 hour service is done in Germany (for now). Barring any abuse, crash or FOD damage, all services are a flat $250, which covers the shipping back to you, even from Germany.

All ECU's are flash upgradeable, free of charge. Any ECU can fly any engine, so all it takes to transfer an engine from one plane to another is an install kit and 4 screws to free the motor. All parameters for all the motors are stored in the engine itself. No need to move or transfer the ECU or fuel pump.

The engines are loud, but then again, they are jet engines

The pilots currently flying them for the evoJet factory are Buck Garza, Paul Bageman, Rob Lynch, and Jake and Dave Bottita. Feel free to ask any of us any questions you may have. You can also check out the evoJet Booster direct support forum at the top of the RC Jets page.
