Easy one! it's personal choice, you won't see a performance gain from either.

You can use that same 4 cell pack to break in the motor too. If you are just starting out, polishing the bushings isn't as critical, but using the right brushes, aligning the hoods, etc. is. My advice is to also get a good soldering iron. You want really good bonds (no cold solders), and that iron is even more critical when you get to your batteries. Hako makes great ones, and there are others. Expect to pay about $75+ for a good iron. Good luck.
i find it much easier to just pay my hobby shop $5 to cut the com, i do everthing else myself. also i dont even solder, i just tuck my brush wires right in the lip that holds the spring in, much neater, easier and never had a problem.

you probably have nothing else to say cuz youv'e never tuned a motor in your life, so you try to poke fun instead of ofer some helpful tips, im sure as usual in your life the only point you have is the one on your head. try it before you knock it and see it makes no difference in performance, just neater!!!

no difference in performance, are you doing anything w/ the brush tensions? Becouse where you describe putting the shunt will definitly increase tension thus changing the "tune" of the motor.

Not soldering the shunt, well anyone would agree that's wrong, a soldered joint is much more efficient than just letting the springs tension account for a good joint!

How many motors have you Tuned? Paying a shop $5 to cut your comm. is borderline moronic, if you are such a profound Tuner than you must have cut comms what, at least 50 times? humm, if you have payed your shop $5 only 32 time you could have bought your own Cobra lathe w/ a diamond bit.

Now see you could of have save $100 or more by now lol, could have used $10 to buy a cheap soldering iron, And we wouldn't even be having this convo!!!

As for the pointed head comment, I'll pardon that for now, as not to turn this thread into a flaming contest!

Now to defend my post to you, your post was so absurd that I truly thought you were kidding, thus my laughing comment.

never claimed to be a profound tuner, nor did i ever laugh at someone elses methods.

trust me not a money issue, time, i have a wife and family and a household to support, do so very well, i have 2 extra comms, so haveing a friend who owes me and is working off debt by cutting comms saves me alot of bs time.

how you can think something is so absurd when you have never seen it done or tried it yourself just shows how narrow minded you are!!

yes, cuz it makes me feel so secure that his business is doing so well that he needs to advertise in a toy car forum, id let him work on my $3000 furnace, especially after i see him bashing someone on a public forum simply cuz he doesnt agree with his method!! yeh, he must be the definition of integrity and must posses the highest sence of business ethics!!!

...or you could just send your motors to me and I'll rebuild and tune 'em for free!

Yup, that's right. Just pay the postage and I'll do it!

Stop it already, fellas. You're starting to sound like 2nd graders on the playground. Let's all be adults and get back to discussing how to tune motors for newbies...

What are we fighting about, anyways? Whether soldering a brush shunt makes a difference or not? This is a quote from Big Jim, who, in my mind, is the motor man of motor men.

"The single shunt wire is only rated at 10A anyway so it really doesn't matter where you put it as long as it doesn't hang the brush.

It's much more important to keep the inside of the brush hoods exceptionally clean than worry about a shunt wire."

Did you know you could just cut the shunts off and not attach them whatsoever? Or leave them hanging? This is simply a matter of preference. We could sit down and measure everything on a dyno, whether soldered or not, and I imagine the results would only differ slightly. I, for one, prefer to solder my shunts. Some may just like to attach them to the spring-hooky-thing. Some use the screw-on type.

If it works for you, and is fast on the track, then AWESOME! Mission accomplished...
