Actually, not defending ACME, but several years ago i bought two ACME Troopers from Hobby King along with 2 of every replacement part, which they had everything, surprisingly. They both lasted a long time of just aggressive bashing, dont think I ever used any spare parts. Even the stock servos held.
We hammered them. They were very "sloppy" and just tightly built rigs but we more than got our money out of them.
Finally the motor went on one and esc on the other and we never fixed them but i was happy with them.....not saying this will be the case though.
