4-Tec conversion

[BrianG]

Yeah, that's what I was thinking. Being belt driven, there's a fair bit of drag just from the drivetrain. And if I decide to go faster, the extra torque will pull a taller gearing easier.

Besides, I did some more work tonight and I really have to get a 60mm motor now...

Why, did you add a bunch of weight? I agree with you on the drag issue. I cannot imagine that any belt car could be smoother than a shaft driven one... Maybe I have not experienced a pro level belt car yet. The tamiya 4wd tc that I had setup for speed runs was so smooth you it felt like it did not have diffs in it. It would barely slow down during off power coasting...

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
