I have been watching this forum for some time thinking the same thing also.

At our MrSpeed trials in Memphis, most of the true speed planes were converted pylon planes. There were people flying clipped wing q500 racers with no landing gear and cowled engines. Then there were people flying converted F1 ships running the venerable OS 46 VRDF, and finally there was myself and one other friend using converted QM15 planes on Cox 15 racing motors. Converted racing planes were always substantially faster than anything else-especially flying wings and Deltas...

I think the other guys are right, "plug and play" seems to have been the mantra for the past few years, and the Whiplash allows just that. "Plug and Play" Speed!---but not the optimum to go the fastest.

The Austrians/Europeans have proven that the way to truly go the fastest is with a slope glider which is built for the task.

That brings up a possible difference in the way Europeans and Americans do things....... Americans generally try to throw horsepower at things to make them go faster. Europeans generally spend their time refining the chassis or airframe and the power delivery.

Neither method is inherently wrong, and it has proven in history that it usually takes a little of both to hit the ultimate goal.
