I think I am going with the WRAITH 7K & Quark 33amp Car Pro Combo from B-P-P. Heres the link, http://www.b-p-p.com/proddetail.php?prod=db_wraith . And I can just use the stock gearing. How would you gear it?

I havn't, I just boiled my gears, then lubricated them all with Traxxas lithium grease. A dual mamba is a waste of money, one moter will be faster then the other, and it will put load on the other motor and cause it to burn up.

It was for a little bit, while trying to replace a broken screw, the screw broke off so now I have to order another part. I also want to say that the stock MLST radio does NOT work well with the Quark. If you have an aftermarket radio your in the clear though.

That would probably work fine. The problem is the throttle band in the stock TX is just wacko.

A dual mamba is a waste of money, one moter will be faster then the other, and it will put load on the other motor and cause it to burn up.
Lots of people have run dual Mambas/Hyperions etc. with no problems. Check 1/18th.com. What does tend to happen is that the diffs disappear very quickly, the tires are extremely hard to keep on the rims and the front wheels never seem to touch the deck. With dual mamba systems, just turn down the power on the motor that gets hot, problem solved.

Incidentally the diff problem is intermittent between trucks. You get some people (like me) who have never blown a diff, and others that blow them every 2 minutes (literally). The difference is getting a perfectly formed ring and pinion from the factory and a perfectly formed diff housing that doesn't allow slop in the bearings.

Lots of people have burned up dual motor brushless systems, one will be faster and created a load which in turn burns up the motor. Some are just lucky, same as the differentials. Im on brushless and have never replaced my differentials, I just boiled and lubricated them.

im thinking about dual brushless , why cant we install the 2 motors without the pinion gears first, then pass a soft dc voltage thru the motors so that they line up, then install the pinions... then, wire them up to the same esc, because the spur gear will lock them at the same phase all the time they should behave as one single motor... of course this is assuming that the esc has unlimited output capacity or you make it so that it doesnt burn itself up...

Theres no point to dual brushless, the cost doesnt weigh out the performance increase in the first place.

If you do your homework you will find that inverted is right. There is no sense in it. They WILL fight each other. There is no way around it.

You know those kids that seem to drift through school without ever doing any homework? They go on to have dual brushless MLSTs. What's the advantage? Tart value and the ability to use stupid gearing thanks to the monster torque. The disadvantages are extra weight and power usage. But it does work, experience has proved this, not theory.

BeatYourTruck.com's latest project is a dual mamba lipo powered Mlst, should be interesting to see how it turns out, eh?

Inverted, I saw you solder the battery with thicker wire and then a dean plug, what kind of battery is that? Why did you do that? Im just curious. [8D]

It's just the stock battery, stock wire gauge. I put on Deans because my wires were melting and it lowers resistance.
