4-Tec conversion

Actually, among higher lever TCs, belt driven ones are typically smoother. This is because of the more efficient transfer of power from the motor to wheels, i.e. cars with drive shaft would have to convert sideways rotation direction of the motor/shaft to forward direction.

The sideways rotation also affects steering in a well balanced car, which is not the case on belt-driven cars.

Because of this and the increase in belt durability, more and more companies are converting their pro level TC to belt. For example, the TC5 is belt driven where as previous generations were shaft driven.

Also, the fastest RC is based on the belt driven MI3

Anyway, shaft is good too, especially for bashing, drifting, driving on asphalt/outdoors since the drive train is mostly (except for spur and pinion) enclosed.

Nice build so far, I want to see how fast you can push that thing.

Good info flipmac, I plan to beat this turd like a red headed stepchild...

Lol, goodluck

That thingy from Nic Case isn't a car anymore IMO. It's more like a rocketship or something like that...

So I finished it up, well, at least V1...

Current config is a feigao 15l with a bk9920. Using a maxamps 2100 20c? 5s lipo. Gearing is 20/41, and it should get me close to 65mph.

All I can say is this setup is not smooth starting at all... The bk startup is terrible... I remember this combo being much better in my 2wd emaxx. Maybe I have better standards now that I mainly run castle escs...

If it was not raining I would have some more info. But I will wait for it to dry up first.

This is also the crappiest selection of equipment that I have put together in a while! Feigao motor, bk esc and a crapamps lipo

Man that is digging through the bottom of the box of old crap you gave up on. Airtonics fm reciever, unclamped feigao, old BK, no name bec, unwrapped 2100 maxamps !! sweeet ! That things going to be serious springtime fun, Da bucket ghetto hoochie mobile

You got it JJ! Getting back to fun brushless. I best that I do not have 400 bucks in the whole deal...

I ran it around for a while yesterday, dodging puddles. I did not have the rrom to get it up to speed, and the tires that are on it suck... I will say it drifts like crazy, and can take a beating...

I need to go to the local mall on a sunday morning early to run it in the larger open blacktop parking lot.

I did get about 20+mins of playing on it and the temps were great, and the lipo looks to be good for around 25-30mins... I may be able to gear it up a bit and try some 70+ mph speed runs. Need to dig up my foam tires for that...

So I have gone thru 2 sets of tires... They were old, but man can this bad boy destroy tires! And I have only put about 5 packs thru it!

So I geared it down a bit, to an 18t pinion, with the 20t it was wheelying at speed a bit much... The poor maxamps 2100 5s is having trouble keeping up, so I purchased some neu 2500 30c cells to make packs out of. That should allow me to push the gearing up and try some speed runs.

I need some new foam tires for it, my old ones off my other tc are all different diameters from drifting!!!

The 15l and 9920 are doing just fine, temps are just fine. Driveability is good too. Even geared for 65 it is doing just fine, and throttle control is great.
