I have seen where ngh has come out with a 30cc gas four stroke anyone know anything about these and how it may work in the hangar 9 eagle? Thanks, Bill
I looked it up. That engine with ignition and muffler weighs over 3lbs! And I don't know if that includes the ignition battery, probably not. The Hanger 9 Christen Eagle II 90 ARF was never intended for use with such an engine, let alone a DLE 20. My Supertigre G90 ring weighs 1.7 pounds with the muffler, swings a 14x6 Xoar prop right at 10,000 rpm and produces nearly 10 pounds of static thrust, even more in the air! with a projected weight of less than 10 pounds, well.... let's just say my Eagle will fly in spectacular fashion, if I can ever finish the darn thing. Plus (oh yes, there's more) lower stall speeds AND lower landing speeds. But good luck with yours.
