Summit with MMPro or Tekin RX8

[kulangflow]

Howdy Folks,

I've done a bit of research on the subject, but I'd like to go ahead and ask the great minds at RC-M.

Project: Traxxas Summit
Batteries: 4s lipo
Primary Usage:
-Primarily trailing (hiking the mountains) and pseudo-crawling (I have purpose-built crawlers for dedicated crawling needs.)
Secondary Usage:
-It'd be nice to have a bit of speed (~30 mph) for the occasional jaunt between rocky places.

The stock set-up is great for trailing and pseudo-crawling, but I'd like to have a little more speed in second gear. I do not want to gear up at all and lose any of the slow-crawling capability. I ran a MMM/Neu 1515 1y for a bit, which was great for speed, but wasn't quite there for crawling.

I'm considering a sensored brushless system. There are many people who are using the Tekin RX8, but I haven't found anyone yet using the CC MMPro with a sensored motor.

Questions:
-Will the MMPro be adequate, or would I be better off with the Tekin RX8.
-Is there another ESC that might work better than those two that I'm not yet considering?
-For brushless crawling in first gear, what do you think would be a good kV to shoot for? I'm thinking something in the 1500kV range as an all-around choice.

Thoughts?

Thanks in advance for any advice!

I don't think the BEC in the MMp would handle all of the servos that the summit has...

you might want to look into somthing like a Kershaw or dewalt motor.

I would use the MMP and use an external BEC or Rx pack.

The MMpro would likely handle the motor fine since it is geared for ~30mph tops, but as said, the BEC might be the limiting factor. I personally would go the safer route and opt for the Tekin; not only will it handle higher gearing better, the BEC is a bit more robust.

...compleatly voiding the reason to get a MMp

I like to run Rx packs anyways, less work for the ESC to do is always better.

Bigger is better, my friend.

Thanks for all the advice!

I went ahead and purchased doo540's Tekin RX8 with the 1350kV motor. I'll let you know how it works out in the Summit.

Thanks again!

Will you be running 6s or 4s?

Glad you got it ! Save's me some money, I was thinking pretty hard about it.

With 4s (or higher) It'll be what you want and need and more !

[kulangflow]

I'll be running 4s primarily. If that's not getting the job done, I'll move up to 5 or 6s.

Please let us know how it does in it.
