Alternative for stock Spektrum motor on Vorteks 4x4 3S BLX RTR

[SeaMan]

Hi all!

I'm looking for an alternative motor for my Vorteks 4x4 3S BLX RTR.
Waiting on my third motor (spmxsm2000) with just 8-10 full batterypacks driven in total (the two motors together) (!!) that's in back-order, under warranty fortunately
Saw some useful posts on the forum regarding stuck motors because of dust, so i'll get myself some double sided tape around the spur opening next when i'll have a new motor!

So I just wonder; do you guys have some recommendations for another 3660 motor that works well with the stock Spektrum ESC?
The EZRUN-3660SL-3200KV-G2 maybe? Or something else?

Thanks in advance!

I have a stock vorteks motor that has like 4 runs on it that you could buy if you wanted to. The plan was 4s so I already had a motor ready for that just wanted to try 3s first

Thank you for the offer Stephen, but i rather have another (better) motor alternative that's probably easier in maintenance, like changing the bearrings, than the stock Spektrum. Also there's a Spektrum under way under warranty so
But again; i appreciate the offer!

Understandable! I don't really have any specific recommendations but I'm running a hobby star now and I have multiple hobby wings that have given me no problems

These are good. 2650kv or 2850kv.

Can you give me some modelnumbers?

Thanks, i'll check them out!
Don't you miss extra power because they are 2850kv? Also; what's the differrence between 3660 and 3670? Larger?

 

[StephenSchandelmayer]

I have never run one around the kv that you are looking for so I can't really say. Just know that my other ones for 6s and 4s are good

The 3670 2850kv is more powerful than the stock motor. It’s longer (70mm) and the lower kv runs cooler. You can gear up (larger pinion) for the same or more speed.

3660 is 36mm diameter and 60mm length. 3670 is 36mm/70mm.

Thanks for the explanation
Sounds pretty good, especially for that price!
Think i'm gonna order that Surpass Hobby 3670 2850kv

I have that motor, and it's great. The torque is so much better than stock, and with the right pinion it's as fast as stock. It also runs so much cooler than the stock motor when driven in the same manner. You will need a different pinion: the Surpass motors have a 5mm shaft vice the 3.125mm shaft on the stock Spektrum 3s motor.

Glad to hear, stoked!
Any advice for a pinion? Still have the extra larger pinion that you get with the Vorteks. It's a 20t vs 18t (stock).
Correct me if i'm wrong, but the stock motor (SPMXSM2000) have also a 5mm shaft, right?

Yes he needs a different pinion but it’s because of arrma’s proprietary pinion system. The shaft on the stock motor is 5mm.

Didn't know about the 'safe-D5' pinion system!

Will an Arrma 20T, 0.8 Mod (AR310876) work on the Surpass motor?

Sorry about that: I have too many vehicles with different motors in them, and it's hard to keep track of the different shaft sizes on each of them.

No. Look at Robinson Racing pinions for high quality. Traxxas pinions are a little cheaper and I’ve had good luck with them.

Edit: just looked up the part number and it might fit. Doesn’t seem to be one of the newer pinions.
