I'm thinking of getting one xxx-s, but I'm not sure it can handle my mamba max combo 7700kv. I've seen several pictures with melted diffs. Balls are overheated from high speed and melt the plastic bed of the diff. What you think about this? Can I replace the plastics with metal diffs from other models or there is such tunning option for xxx-s? Is there any other problem I should know about, when using such powerfull combos?
Thanks!

I have 2 of the Losi xxxs that I use as speed cars. Both have MMP w/ 7700kv motors on 3s. I'm running close to 100mph. I do occasionally have to replace the diffs. I'm running gearing around a 86t spur and a 40+ tooth pinion. Most of the time with the diffs is because it looses traction then regains traction again.
