the suspension arm mountrs are prone to breaking of the chassis on hard impacts so good idea to keep one or two handy as well as a parts (gearcase) so you wont be waiting for spares to arrive if you break something
There is no design flaw with the way the rear arms attach with this chassis, like the other reviewer stated. The only flaw that other guy has is his driving!!
I've only ever had to replace the chassis once in all the years I've owned my DF-02, and that's about 6 years, and it broke because I let a complete noob drive my car and he hit a metal pole and it broke at the front, not the rear.
The only thing to be aware of is to not over tighten screws or else the plastic could strip with repeated unscrewing of them. Better yet, don't use the stock tamiya screws. Use the much finer thread 3mm screws. The finer thread will mean the plastic won't strip anywhere near as easy.
Well every time i have a massive smash for some reason,the back swing arms break off the chassie body and i always buy a new chassie to rectify this problem.
These are the original Tamiya df02 chassie for your Gravel Hound and Plasma Edge
They are an original part of the df02 chassie.But i think the back end where the swing arm is attached to the chasie is a desighn flaw,i have broken 2 chassies so far and im sure to break more.
