would recommend reading this, and seeing if the shop has the piano wire available to do this

I've only broke 2 parts on a DF-02 (I own 2) in 3 years. 1st part was broken exactly as it is shown in that link I posted, and since doing that mod 2 years ago it hasn't broken since. Since its a cheap mod, dirt cheap mod that is easy to do I HIGHLY recommend doing it it cost me like $3 USD to do 2 of my DF-02's(I said it was dirt cheap)
Other part I broke was a rear shock tower, but I can't blame tamiya as it was a DF-02 bootleg that the tower broke on. My original 3 yo DF-02 the stock rear tower is fine on.
For an example of how stout the RC is its designed to go around 20-25mph mine hits I'd guess around 40ish as it has a BL setup in it, and has taken BAD crashes and since the mod hasn't broken any chassis parts. I've also had it cartwheel, flip end over end, and jumped it on concrete with nothing breaking
