Uh... dunno- I do not have an educated guess...
It was just flying nice and I had it trimmed out and it did one of those famous slow rolls into our fine planet- RX ok, servos ok, range check fine...

How much carbon does a Whip contain? Unfortunately you are able to check that now...
Since the Whip is very rigid check your switch, battery and RX for vibration damage.
Also watch out for pipes that touch the header... IMO it is better to have some distance between the pipe and the engine and burn out the coupler every now and then...
In setups where the pipe hooks up to the engine directly it can be helpful to make a mass connection between the engine and the radio system...
