Well mate i have used my bulldog and treated it like a real tank i have taken it through water up to its shell through very deep mud sand rocks and i eventually broke it in 2 inch deep water.LOL
Ive broken the exhaust pipe that goes to the little exhaust on the dog ive stuffed the smoke system i nearly broke its speaker with the water runs but that just dried out and i also wore out its back idler.
So all i can say is have spare circut boards and have fun.
And ive also got a panther i have mainly just taken it rock driving and through shallow water and its still running fine.
Kind regards pantigerman.
