The DeltaHawk is still unproven in my book as far as power, longevity and reliability goes. No way I'd be the first to drop $90K on...

As quick as possible will be good: they have only been developing the engine for... Aug 23, 2019 at 9:46 PM 4. ### rv6ejguy liked TarDevil's post in the thread Raptor Composite Aircraft. Yeah, my thoughts. High, but not horrible considering they will get thrust for you at that price. The bigger issue with a Deltahawk...

These engines were designed and built by experts,... Aug 23, 2019 at 2:54 PM 8. ### rv6ejguy replied to the thread Raptor Composite Aircraft. Unfortunately the pressurized aircraft requires a turbocharged engine and either model of turbocharged Lycoming 540 or Conti 550 would...

He thinks it will all be ok. He... Aug 23, 2019 at 3:30 AM 10. ### rv6ejguy replied to the thread Are dual spark plugs still needed?. Use a reliable, crank triggered EI and single plugs. No moving parts to wear out or fail. No maintenance, no failures in 430 hours on... Aug 23, 2019 at 12:15 AM 11. ### rv6ejguy liked wsimpso1's post in the thread Are dual spark plugs still needed?. In what type of engine? Traditional airplane engines? Automotive conversions? With what type of ignition? Magneto? Electronic with... Aug 23, 2019 at 12:08 AM 12. ### rv6ejguy replied to the thread Raptor Composite Aircraft. The DeltaHawk isn't affordable- something like$90K. New engines are not available. Peter needs to dump the diesel which will get rid...
