I put a lot of power in to my 1/18 ruckus and keep breaking drive shafts. I was hoping some one would know of some upgrades to bullet proof it.
There are no Chinesium knock offs. Hot Racing was literally the only option.I did manage to get a hold of Hot Racing once and asked about the cvd shafts, albeit it was for the 1/10 scale cars, mainly the Torment, they were pretty confident about there not being anymore made in the foreseeable future.
You could look for some of the Chineesiem knock offs maybe try those?
