Landing a backflip, or any jump for that matter, with the throttle open (you giving the truck gas) is horrible for your drivetrain.
Practice jumping, using the brake and throttle to adjust the cars pitch, then land with no throttle and no brake.
Cheers.
Not good to rev in the air either. Holding it WOT is a good way to kill a motor. I'm sure theres plenty of people who do it and haven't had a problem but revving with no load is not good.
