Here is my Whiplash V2 eating up the sky with the Hanson 300 and zimmerman muffler:

Note how the rpm holds very well throughout the maneuvers. I had another video that was lost showing full power climbouts and such, sorry about that. Anyway, you get the idea of the performance, which, honestly, is as good as a nitro in my opinion if not better in some cases. This machine can climb 4000ft/min.
When it ran out of gas, there was 1 drop left in the corner when tilted...took a picture, see below.
As the saying goes, "good to the last drop," even while doing 3D
