There are no real probs with the truck, well the rtr there are a few.

The only reason why most people don't think about the mad force when it comes time for a new truck cause its no real known, and since tower stopped caring parts for them, that killed the force, there still in production, but only a few sites still have them, kyosho when out on there own, so they have replacement parts, u just have to pay there price, there are a few places that still Carry parts for them such as: ultimate hobbies, toyhause , and a few others, but the truck is very well built! just with the RTR's is the engines have been going sour for some reason? but kyosho will replace them free of charge.

But there is good news tho!

Gill losi Jr. has joined kyosho, so now kyosho is part of team losi, and hopefully soon horizon will be carrying kyosho parts!
