Thanks for the tip. I've now set the front brake to 40% and the rear to 25%...which should hopefully make the truck more stable under braking. The only video I've been able to get is this one:

It's not much...I filmed it while driving on my phone, and it's just mainly blipping aroundat low throttle...apart from at the end, when my trigger finger slipped a bit! This thing has got a fair bit of power.
I'm working on getting a proper vid, I promise.
