What about using brushless? What would be a good choice? Thanks

Sensored brushless is really needed for crawlers, otherwise you get low speed cogging which is not good.
Keep in mind, going sensored drives up the price of the motor & ESC.
Most of us run brushed since they work well in crawlers.

The exception is rigs with worm drives, they are hard on motors so brushless is a good fit.

I agree with Mike and Charlie.
The key issues are:
- What rig do you have?
- What do you want from it, in terms of low speed torque and top speed?
- How much money are you willing to spend?

As you can see in my sig I run a 35T brushed in my LCC because it's cheap, but for me it's slow.
I plan to go brushless (motor, ESC and programmer), but it will cost me some $250 purchase, plus international shipping and an additional 25% sales tax on top of that.
Had I not been running a crawler with worm drives I'd stick to brushed motors, but got a higher quality one...

How long are the stock shocks for the ax-10 scorpion?

Take a quick look at this:

RCCrawler.com- Your #1 source for Radio Controlled Rockcrawling!

And welcome to RCC

Hey man the best bang for your buck might be an exceed mad torque I have had a few minor issues with mine but they are easy fixs the only thing I recomend when you buy it. Is that you also buy an esc for it because mine burnt out within a week of my having it but so far its been fine working on building a tuber chassi for it and getting rid of the plastic steering knuckles and when you look to upgrade it you can also use some parts off of a axail ax10 which is a better brand with better quality parts

Man, I sure have learned alot from this section of the forums, props to all the vets who help us newbs out!

[mitywhitie]

Loc-tight your new crawled lesson learner! So I just jumped down the rabbit hole and bought a redcat… I'm a total newbie at RCing so this site has been huge!! But no where did I see loc-tight you new truck I presumed. That for a sport like thisthey wouldcome that way but atlease with the CAT this is a no so to all my fellow newbs LOC-TIGHT. Other than that. I'm sohooked it not funny!!

Does anyone know if I can get custom cvds made. I have a tube chassis that i am building and can't find the right length center drives

Can this be fixed? It won't charge...Can I tap the broken wire into the other black one?

[CrawlinMike]

No bam don't splice it into the other! This happens sometimes and you're using fairly cheap packs. Just nip it off and charge it as a nimh and keep an eye on it. It'll last a long while more. Or if you are a lipo paranoid guy just dispose of it and replace it.

DONT charge as nihm... thats only to revive a pack... and you do it for like 5 seconds..........




just charge it on lipo charge, not balance and you should be able to charge without that plug

Thanks! Will it damage the battery by not charging it on balance?

[CrawlinMike]

FACEPALM........ There really isn't a difference between charging it on nimh and charging on lipo without the balance plug. Yes eventually the pack will get off balance and likely swell.

umm no my charger checks voltage even when in charge mode only and knows a 7.4 is 2s and 7.2 is nihm.... not the same...

no just the cells arent "ballanced" so it could swell or go bad sooner then it was supposed to

[Olle P]

Another "maybe..." hit-or-miss option could be to somewhat carefully open the hardcase and solder the lose lead back where it came from.

Can cause more damage though, if you happen to short something or damage a cell casing.

The peak voltage the charger looks for is different between NiMH & LiPO, so don't charge a LiPO as a NiMH.

As mentioned, a short NiMH/NiCD charge is to bring up a very low LiPO pack so a charger will charge in a LiPO setting.

PS, if the broken wire was the end one, you could attach it to the heavier wire to fix the balance port. Since it's the middle one, you would have to open the case and attach back on the cell. These are usually soldered with "lead free" solder which requires a fair amount of heat to melt.
