I have no idea if a Killer Bee is an original Cox product or not -

Anybody have experience with or know if the Killer Bee will actually turn bigger props like a 6x3 at higher RPMs than other Cox reedies?

Also, is a Killer Bee backplate any different (in terms of performance & excluding color) than a stock product or Surestart engine backplate?

Thanks for any help here -
