Ok i am in a dilemma. I am currently building my SCX hybrid and now i am starting rethink my motor for the rig.

I have the holmes hobbies 14T cobalt puller mounted in it right now but I don't believe it going to make enough rpm even on 6S for what i want. I am now looking to go with a brushless motor instead. I still want to be able to crawl with it and with a the summit tranny, 6S, and a 9T pinion coupled to a 68T spur, i think its very doable. My main concern now is current draw. The truck is relatively light when compared to anything 1/8th so that leads me to believe i will have a much lower current draw than other rigs.

My batteries are a pair of hyperion G3 CX 2100mah/25C 3S lipos and i want to run them in series.


I was thinking about a NEU 1700kv or maybe even a NEU 2200.

ESC is a mamba monster.

DISCUSS!

well i called up chipster and talked with him about it. He got me thinking that maybe i am veering off the course for what i originally wanted this truck to do. At its core, its a trail truck that will be crawling around a heck of alot more than it will be scooting around on pavement.


That being said, with a top speed of around 15mph WIDE open on 6S that may really be as fast as i want a trail truck going.

I don't think i can match the "crawl-ability" of a puller motor and i really don't want to sacrifice my low speed control for a higher top end.

Maybe i was getting a little speed bug in me. lol. I am going to run the truck with the mamba monster/14T/6S this week and see how i like it

Besides, at two years old, 15 MPH is gonna be quick anyway...

Id try to stick with what you have rather than going to brushless. If you went brushless on 6s, I would think trying to get any low speed control for crawling would just end up cogging. Maybe not though but Id stick with the puller.

i need to turn 1733 rpm in HIGH gear to get 1mph. I am sure it would crawl like a champ no matter what motor i put in it.
