Oh and back to your question about it being harder to turn, that's definitely not a bad thing at all. The motor in my Motley Crew (boat) is very hard to turn and it's a powerhouse.

The reason for it is the stator (windings). If it's slotless it'll turn over really easily, but if it's a slotted stator you'll feel it kinda snap into place as it passes each slot.

Slotless stator:


Slotted stator:

oh got it now!

I actually got a little scared I thought the motor is old n rusted etc so its having a hard time moving.

so to my knowledge most of these brushless motors can be rebuilt. so does that mean they can also be upgraded? like adding a better rotor to improve performance is that true as well?

Rotor and stator need to be matched together in size and number of poles. Tekin (and others) sell different size rotors, and different wind stators for some of their motors, but it's not like you can just grab any random rotor and put it in any random stator and have it work.

A local guy I normally trade with picked up a 150c lipo battery. I asked him him of it makes a difference, the discharge rate does it make a difference. he said he see a huge dofference in speed n power when he switches from his 40c to his 150. like almost a 30%+ increase in performance. i didnt believe him so I wanted to ask you guys does it really make that big of a difference?

I call BS on 30% increase fresh off the charger unless he's pulling a TON of amps (40c 5000mah can do 200a constant).

The big benefit to higher C packs is that they have less voltage sag under load throughout the discharge cycle. The result is that you have more punch towards the end of the run than a lower C pack does.

I run 50c packs in my 22T and find they're very consistent over the length of a 5 minute qualifier or 10 minute main. They're even pretty consistent over a 15-20 minute practice session.

I didn't think of that all. capacity drops so the amperage will drop...lol I'm a noob.

well I sold my ZD racing esc and the motor I didn't like it a lot it was too slow for me. I actually picked up the 4 pole cc motor and a ez run 6000kv motor.

also picked up a stampede shape shifter roller which has been converted to a truggy and I gotta say this thing looks really cool. it is 4x4 so I'm gonna try n run the cc 4pole 4600 kv with a small pinion and see how that plays out. Nd use the ezrun 6000kv with the rustler.

oh and I ordered 2 new esc's. ones a car esc, turnigy 100a

and the 2nd one is kinda experimental. its a heli/plane 70a esc and up to 6s capable. I'm going to try it with a car and see how well it works. it has a bec intergrated. I understand there is no reverse and brakes are different too but I'm gonna mess around with the settings and just try it out see how it goes. any thoughts/ideas on that?

The "brakes" on a heli/plane ESC are nowhere near powerful enough for actually stopping a car/truck. It's just meant to stop a prop from free wheeling in the wind.

I wouldn't suggest running a boat ESC in a car, they're meant (and specs based on) to be water cooled. Without cooling they'll run much hotter, and won't be able to take as much current as it's rated for.

I'm not sure the brakes will be useful with that either.

put a thermometer in the trunk and see how hot it gets in there. if it clears 170, then I wouldn't leave my stuff in there. I am guessing you should be ok.

Hello all

I just purchased a LRP X12 Vector 3.0 turns 11,600KV motor. I'm planning on using this motor with the Traxxas rustler and I'm wondering is that's okay. Website doesnt say whether this motor is for on road or off road and I know from the specs one would think its definately for on road cars. I want to know if anyone ran one of these in a lighter truck such as a rustler.

2nd Question is max voltage is listed to be around 6 volts, the only lipo I have is actually a 3s. Would it be okay if I ran a 3s lipo with this motor? Or should I buy a 2s lipo? I have some nimh and nicad batteries but idk how well they'll perform.
