i've had a FG Marder.. sold it.. cos it's so sluggish.. kinda.. i wanted a fast and nimble Savage instead.. and the diff on the largescales really really needs to stop mashing up stones.. well you can fix it.. but hmm it sucks

and i wanted 4wd instead of 2wd.. also less weight when moving them from your car to your house/garage.. easier to work on inside.. smells less

and for a large scale to keep up with a nice nitro truck it needs alot of cash put into it..
and if you dont look for the most performance there is good engines thats really reliable and still runs on nitro

and yes.. the STS aint one of them
