Default trying to retro fit & upgrade my tamiya c11 mercedes le-mans 1/10th car.

this was my 1st so called "performance" r/c i purchased back in 1990. i've been away from electric r/c a long time & recently went to my local track to watch the electrics race & i must say that i was impressed. finally electric seems to be up to the standards i was wishing for all those years ago. i used to get so annoyed with short run times & long charge times & lack of speed compared to nitro. well now that has changed it seems. so i went into my garage & after much effort fished out my old kit. you'll probably look at this kit & laugh what with the 3 step speed controller (crude but effective), & bathtub chassis (compared to carbon fiber chassis these days). my questions to you guys is this:- as i don't want to spend too much money on a new kit yet, is it worth doing this kit up to modern race specs & if so what should i do to it? it did come with the mabuchi 540 sport tuned engine, is this good enough or should i get one of these new brushless motors? what is a brushless motor (please don't laugh to much)? what does a electronic speed controller do? and what batteries should i look at? i don't mind that it is only 2 wheel drive & not all wheel drive but i do want it to be fast on the straights & quick accelerating out of corners(don't we all). please keep in mind that i am a novice with all this new electric r/c technology so if someone could take the time to answer this thread & explain to me what each mod will do for the kit it would be greatly appreciated.

THanX guys.

p.s. if anybody actually knows what the model no. of this kit is it would help me track down standard parts & new bodyshells for this kit.
cheers.

You'd be best off getting a new car. That would make a really good shelf queen though!

Patience, money and ebay can yield a lot of reward. There's a few of these cars BNIB on ebay at the moment and more than a couple of bodies. I guess other spares can't be far behind.

To do the kit to modern specs can be a futile exercise because you might find you can't race it anywhere. Check with your local race track and see if you can enter one of their classes with it. If they have a silvercan class you're set. If not, it may actually be cheaper to buy a new car. Not because it would be more competitive but you can actually buy kits that are cheaper than all the parts you need. And if you have to get a motor/esc, I wouldn't jump in the brushless thing if money is a constraint. There's plenty of top brushed gear being dumped on ebay for peanuts. Look and ask around before you buy.

Tamiya rereleased this kit, but the first thing I would do is get a basic esc, such as a duratrax, a fresh set of tires, and a new battery. Here is a good source for bodies tires and just about anything else you may need

I got 4 of these cars myself (C11, 787B, Jaguar and Ferrari F40), and they are pretty effective in F1 class.
The chassi is in basic a F101/F102, so lots of F1 parts fit.
The downside is the body is too heavy to be truly competitive.

F104 tires fit like a charm, rear axle is same as F103, same with some parts in front suspension.
Just add a F103 damper. No need to go all carbon on these as they work pretty good as they are.
Make some turnbuckles upfront to stiffen steering and have fun with it.

But like the others say... You might be better off with a new kit (F103/F104?).
These cars are getting very rare so better keep it as a shelfqueen.
