Re: Question on motors and genereal initial upgrades
 

That's a common misconception!
The speed/torque relationship is as good as exactly the same for all motors of the same design (with different Kv). The only difference is the voltage and current required to reach a specific speed and torque.

The 3100Kv motor when fed 5.0V is totally equivalent to the 1200Kv motor fed 12.9V.
The difference lies in how much current they draw, with the 3100 drawing ~2.6 times more current.

Re: Question on motors and genereal initial upgrades
 

If I were to put a Roc412 into the RR, would there be anything else that would "have" to be upgraded at the same time to avoid issues? I would like to upgrade all the electronics at once, but will more likely spread out over time...

Question on motors and genereal initial upgrades
 

That would be the same list as in my earlier post (stock ring/pinion, stock lockers, plastic knuckles/chubs, plastic links and trailing arms, maybe WB8 driveshafts). The RR10 is basically Wraith axles (which need beefing up), a hybrid of Wraith and Yeti suspension components (which need beefing up), and a Yeti tranny (pretty solid). From what I can see in the pix and write-up, the transfer case maybe new to the RR10, so it's hard to say how that will hold up to a ROC 412 until people start using them. You can be one of the guinea pigs for everyone else, lol.

Don't let @new2rocks tempt you too much into brushless, he's a bad role model :D :shock:

Re: Question on motors and genereal initial upgrades
 

Was kind of thinking that I could upgrade those pieces as I go (or as they break). then again, I just had the drive shaft fall out of my '74 Bronco, certainly wasn't the best idea there :shock:. Then again, my daughter won't be sitting in the back seat of the rr :lmao:

Just want to make sure that I won't mess anything up if I don't upgrade the ESC for example when putting in an upgraded brushless motor.

Re: Question on motors and genereal initial upgrades
 

I'm the "upgrade the known weak points before it fails" kind so I would normally say go all out with links, trailing arms, HD gears, spools, and steel driveshafts but driving my buddy's relatively stock Wraith changed my mind. His truck runs a Holmes Puller Pro 3500kv and MMP on 4S with only steel trans gears (already in the RR10) and HD axle gears for upgrades and it can pull standing backflips given enough traction. The only thing that has failed so far is the servo case from hitting a rock at 20mph and launching 8 ft into a tree.

The point is stock is pretty durable so drive it to find the limits before going crazy. Oh and skip the ROC412 and go straight for the Puller Pro, it is way more motor and doesn't break a sweat on heavy rigs. "thumbsup"

Re: Question on motors and genereal initial upgrades
 

Is it necessary to upgrade the ESC at the same time as the motor, or ok to use the stock ESC?

Re: Question on motors and genereal initial upgrades
 

The stock ESC is for brushed motors only so going brushless requires a new ESC.

Re: Question on motors and genereal initial upgrades
 

glad I asked :mrgreen:, though I know they have positioned the RR as "brushless ready"...wouldn't that mean that the ESC should be ok for a brushless motor or no?

Re: Question on motors and genereal initial upgrades
 

"Brushless ready" in Axial language just means the transmission doesn't have plastic gears blow out under moderate power.

Re: Question on motors and genereal initial upgrades
 

Got it, thanks for the clarification! Does anything else need to be upgraded in order to run brushless?
