I thought that you were not suposed to shorten the motor leads. I belive there was a thread about that on here not to long ago explaneing why
|
You shouldn't shorten leads on motors like Feigao, Neu, etc because the leads are just extensions of the coil wires, and only the last inch or so has the varnish removed for soldering. It's almost impossible to solder to varnish-coated wires without somehow removing that layer.
Motors like the Mamba max motors are ok because the leads are just regular wires. The connections between the coils and the leads are done inside the motor. The CC Neu motors look like they fall into this category. |
Alright so shortening motor wires will help reduce noise, what about those ferrous rings found on the ends of Gamming controllers like the Ps2's controller- i have one but i dont know if it will help any.
should i braid the Pwm wired (red black white-servo connector)? |
The ferrous rings almost doubled my range in my airplanes before I went to the futaba fasst with them. It worked really well ,Took all the funky glitching out.
|
Good to hear, ill try it out once my v3 gets here
What do i Run through it? the esc-to-rx wire or the antenna? |
yeah wrap the lead that goes to your rx form the esc around the ring.
|
Im using one out of a Ps2 Controller, its more cylindrical.. i will see what i can do
|
so is it a bad thing if the leads are stubby?
|
if it is the cylinder type just put the wire inside. what do you mean stubby?
|
Motor wires, they are 7 1/2'' long right now. i want to shorten them to like 2".
sorry about that vague post |
I used some of those rings when I getting bad glitching on my crt.5 (4s a123, feigao 9l, mamba max, futaba 2.4ghz). I could even notice it with just the power system sitting on my bench. Ferrite rings made things worse for some reason, heeeaaaps worse. electronics positioning was not the problem (I even isolated the high power stuff completely on my bench when i was testing).
Still never figured out the problem *shrugs* I thought it was the MM and sent it back and they said there was nothing wrong with it. Not the case, I just don't run it anymore. Pity, really. Just waiting till i cbf posting it up here for sale heh. |
seems eerily similar, but i dont know if its the motor/esc or the receiver.

And yea for sure! I couldnt be happier, maybe a smaller RX, but thats fine Quote:

I have a spektrum receiver sitting here but no money for a module Lol... soo close but yet soo far
|
Well, I know someone who wouldn't mind an extra Spek receiver! Gotta use the remaining 24 model memory slots on my DX3r for something... :whistle:
|
My problem seemed like the batteries voltage was dropping so far it reset the rx (i could see the rx light go off and watch it reset), but i tried all kinds of high powered lipos and stuff too, the a123 were just the standard setup, and it happened with the motor not connected to anything as well - not even a pinion on it, I'm pretty sure A123 cells are up to spinning an unloaded motor without dropping below 1V/cell lol... I can't figure out what it is, and havent to this day. I've used the exact same setup in other cars without problem, it is really really baffling. Like I know there is something I'm not thinking of, and its really frustrating lol.. oh well.
|
A few questions:
- Were you using a BEC or Rx pack? - Were the rx pins dirty? Or, they may have a cold solder joint and making/breaking contact. - Is the antenna sound? I had a Spektrum antenna that was flaky and had odd stuff happen until I replaced it. Was a PITA to solder though because of some coating on the PCB. |

Generally, shorter is always better, though it's not really practical to shorten 10ga wires that much, unless you have space issues in your vehicle otherwise. The worst things that could happen if your wires are to short is if you decide to put the motor system in a different vehicle and suddenly the wires don't reach to the esc. You'll have to solder on an extension. This is why I prefer motors with solder tabs, in which case you don't need to worry about over-shortening the wires. In fact, I just decide to rotate the MMM 90 degrees in my 8ight and even though the MMM bullets only moved an inch away further to the motor, the wires had to be about 2" longer just because of the angle required to bend the wires. |

Well my V3 should be here by monday. but i Think I eliminated the glitching problem
Spektrum Rx- I got from a trade for a charger, and some miscelaneous stuff Module- I payed 60 Bucks for. So now im in the 2.4ghz club and I like it soo far. And I just got done shortening the motor leads down to 4 inches. Esc will be mounted behind the motor on the chassis. |
Hey guys a bit of an update
Just ran the truck for 20 minutes, all wot, jumping speed runs etc. at the end of the pack the motor was 110* esc was 120* and zippy batt was at 115* This was geared for 43mph on 4s lipo :) |
What is your gearing?
How does the Neu-Castle compare to the same Neu motor (performace-wise)? Sorry for the questions, if they've already been answered in earlier posts but I am getting dizzy going through the previous ten pages of posts. |

for 43mph I have never run the real neu, so I couldnt tell you:smile: |
I am having some heat issues with mine. Geared for 38 in an e-revo I am seeing 170+ on the motor. It has lots of power though!

Update:
All slotted rotor-motors(say that 5 times fast) Will be hard to turn by hand. The maximum Shaft play is approximately 1-2mm |
To clarify, the rotors are not slotted, the stators are...

Thanks speedy :) |

So hows the the 2650 run compared to the 2200? |
The both run great. the 2200 is in my Matrix truggy on 4s, and the 2650 is in Eovnu87435ds's hyper 7 on 4s.. pretty sure neither has seen over 140 degrees
|
What is the weight difference between the 2200 and 2650?
