  3. rv6ejguy liked BJC's post in the thread Raptor Composite Aircraft.

    Their engine (180 HP) is not enough HP for the Raptor. As quick as possible will be good: they have only been developing the engine for...

  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...
