Ali,

No, evoJets is not the same. Hammer engines supplied an older generation to Graupner for the G-Booster engines, and I am not sure Graupner is still selling the G-Booster engines. The evoJet engines were the newest generation engines, with only a single fuel line / valve and updated electronics.

evoJet is now making all of our engines in-house.

Please let me know if you have any other questions.
