If you’re really gentle, you can bend it back. I’ve done it multiple times when the damage wasn’t too bad. If not, send back to Tekno and get 50% off the replacement part.
RC chassis do bend in order to provide traction. That flex is part of why they are fast. Now bashers like to lock things down with aluminum braces for that very reason of protecting the driveline. Basher chassis like M2C are also going to be stiffer (and hence, slower on the track).
If you’re planning for hardcore bashing or jumping, you may want to consider a few upgrades. There is plenty of aftermarket support for the MT.
