My question was more so to get an idea of what type of motors you were using and how well they work out for offroad usage afterwards.
For example, if you guys are using say 1 cell motors or motor configuration 'X' for this class and find they are not good for offroad usage later on, that info would be helpful to get an idea if this is pretty much something you keep one motor for, or, you can look into reusing the motor later on from a competitive standpoint.
