Here's an advice for both of ya, to keep the front end intact when you make a direct impact to a tree or a deck:

Use the RPM wide front bumper with either the B4 or T4.

I once drove my B4 with 10 3300nimh cells and a 1920/8 motor and directly crashed at the wall at full speed.
Guess what, nothing happenned to my buggy, but only the RPM bumper sufferred from a few scratches.

Its a must for a brushless user.
