Summary

this upgrade for the traxxas trx4m Defender goes in the front of the shell to change to center of gravity from the rear, to more so the middle. i found that it makes a pretty large difference, going from about a 35 degree incline around 45 degrees. there is a slot in the front of the weight to put something that is more dense that 3d printer filament, (i chose nails) and it gives you an opportunity to put something that will weigh to the amount of your liking. it fits perfectly so do not mess with the file to much, its fine tuned for stock trx 4m defenders, if you need to really modify it that's fine though.

for installation, no removal of parts is necessary, just make sure the little nub at the front goes into the slot connected to the windshield, and make sure to have supports on the nub.

print at 100% infill if you want the piece to be heavy enough to make a difference, because it really does.
