Smile Hey guys!!

I own a Traxxas t-maxx 3.3 but now I want to go electric on road. and I got a used 4tec for 40 dollars off a friend. I've gotten most of it running again but i want to go brushless and I want to go fast! i want a 3.5t motor but my question is this, with that motor do I have to do lipo or can i stick with the standard 6cell 7.2 volt batteries that I have? Thanks guys. I dont know anything when it comes to electric.

I would really think twice about putting something as hot as a 3.5 on a 4tec. They don't handle the greatest, so with that much power, it might get expensive quick.

Also, for speed runs, Lipo is where it's at. NiMh cells can get worked pretty hard, even with higher turn spec racing motors. Pushed hard with a low turn motor, they'll see even more abuse, and lower grade cells can die in the best case, and vent/burn in the worst case.

What ESC are you planning to use?

Yeah, it is.

If you just want to keep up with a .15, less than $200, Traxxas VXL system.

Waterproof, will work with your NiMh packs [just watch motor and battery temps], and if you want to get real crazy, a 2s lipo will be faster just due to weight savings, and a 3s lipo will be a land-based missle.

Yeah, it would work, but not with as much benefit as a sensored ESC.

traxxas has vastly increased their upgrade program. it includes electric motors. esc's and even radios. check www.traxxas.com

and the vxl is a sensored esc traxxas just doesnt have sensored motors

the electric 4-tec is a very old design that traxxas has down little to update. i am worried that the plastic is too flexible and you will get your belts to skip. i would stay above 6.5t motors and just get a 3S lipo pack when you want to go really fast in a straight line. other wise some decent stick packs with good connectors like traxxas or deans will be plenty fast to have some fun. to keep up with a nitro-4tec, even the older ones with the pro.15 engine you will probably have to wait until you can invest in lipo. until then you can get close by have a set of high speed gears for doing short straight line speed runs.

the bandit VXL will be awesome and can handle lots of powers. it should keep up with an older nitro4tec and then blow it away if/when you go lipo.
