Show me a link to it please because I would be interested in that. I've never seen one for that price. I have always just bought the sleeve, piston, and rod separately.
It's because the RC was never designed to withstand what you do to it. And the metal plate is aluminum so how much does it really weigh? And you can do a piston, rod, and cylinder for just what I said.
The Losi is probably the best one (and expensive). The Tmaxx is the one to have. I've had a bunch of everything and the Traxxas are the best I've had for beating up. (I presently have a 3.3 Revo for my main truck). They are kind of disposable and parts are as cheep as dirt to buy or replace...
