Very noob question but are bumpstarts universal for all cars and truck. Is there a bumpstart that will work with a buggy, a stadium truck, and a monster truck? sorry for the noob question.

No, they are not universal. There are very few monster trucks that are set up to accept a bump box so there are not many boxes that will work with them. Street cars and buggys are much more likely to be able to bump and the boxes can probably be set up to start several of those. Don't know about the stadium trucks.

Ok Thanks

I have the AE team bump box for my tub RC10GT (ST) and it can be set up in many configurations.
It also can be run off a 1/1 12V car batt etc... or 2 7.2V stick packs.
