Shame I bought the boat AFTER i read that post lol.
You however, can get some fun out of it by overvolting it to 12v... i did this for a while, and although it most likely will smoke the motors, after examining the controler, it actualy uses 15A relays for control, making it probably quite decent! (radio range is awful though)
Me and friends delight in hacking up toys like this... and we may make a vacuform hull using the NQD as a mould, resulting in a much lighter hull!
By the way, my names Angus, from Australia... combat robot builder.

Expect some hardcore modding soon.
