Yes both of them are big and wont fit regular 1/8 pinions???

[dgfordman]

i just got a fxr and hooked it up to my 2s 1500 lipo and a 35t integy with 9 tooth pinion and i need more torque. it works good, dont get me wrong but, it stalls out at low speed real bad. would 3s help with torque? it allready gets hot at low speed. recommend a new motor or ? thanks

Get 3s, that will bump your torque. It gets hot already, is there binding in your driveline?

what cheap motors would you recommend for a clod based super.......def want speed. running 2 22turn singles now. Also csn you reverse rotation one or is it something I would do?

[Thorsteenster]

Hey John, I got a 10T Cobalt Puller from you awhile back and I'm finally about to use it.....I think.
Wanted your opinion on how'd it be with a 3:1 or a 4:1 reduction running into a 1:1 t-case with TLT axles and 4.25 - 4.5" tires. This will be in a scaler, and I can gang the 4:1 up with the 3:1 but with the length of the Cobalt was thinking of just running one or the other.
Other specs will be a MM and a 3S A123 pack.
The 4:1 is an RC4WD GRU, the 3:1 is an Master Airscrew GRU.

Hey John, I have an mrc and am debating on either an fxr with no external bec, or a cc 1/18 sidewinder and a cc bec, I already have a castle link, but have heard lots of really good things about the fxr though, just asking your opinion on what would be a good esc or if you'd have another suggestion I'll be running mainly 2s lipos but will use some 3s as well. I also am running a 645 for steering and thats it. Thanks for all the help, or should I look at the b1r

I send out my motors with zero timing. You may need to make small adjustments to timing to reduce motor heat or arcing. It is a simple task.

You want more speed than you have now, or less? 35t cheapy motors are always good.

You will want a good bit of reduction. Most trannies have about 21:1 reduction in them, so chaining the 4:1 with the 3:1 would be a good idea.

With 3s you really may want a BEC, even though the MRC is very light. On 2s either controller will work well. I use the fxr in my mrc, 2s, no BEC.

With any mini ESC I would suggest an external BEC

I have done some searching and can't seem to find the number of turns the Cobalt Puller 454's have (and the 500's).
I know I can use kv to calculate rpms but I am just trying to see the number of turns for ESC compatibility reasons. Thanks.

[JohnRobHolmes]

You can't use turns for ESC compatibility, as the motors are 5 slot and smaller than a 540. What ESC and voltage do you plan to use?

I want to try this http://www.teamnovak.com/products/m2_combo/index.html

with two Cobalt 454's or 500's on 7.4v. Can't go over 7.4v with that ESC so I have to go with a smaller motor but the ESC can only handle 27t 540 size motors. Clear as mud?

So i was asking if I could use your motors with that ESC based on their number of turns. But its a different sized motor, so i might have to contact Novak. Just want to try a different setup on the 2.2 rig and that ESC would be cool to try. I dunno that ESC my be crap.

I sent an email to Novak to see what they say.

I have one of your 550 puller motors. I was at a comp ran all 4 courses thing did great as always then it just stopped. The thing i noticed is when u spin the motor it would start working again, then when you stop nothing. Do you think i need new springs and brushes? Also are there some things to look for. thanks

2s vs 3s torque?

could you give your expert advise on this thread please. i'm looking to get the ability to turn the tires slower and more wheelspeed and don't know if i just need 3s or to switch from 18.5 to 21.5 and get 4s.

also looking for input on the brushless ESC's that are out (MM pro vs tekin rs) for drag and hold brake or how far out you think your brushless might be. thanks

On 2s you should be fine with the 454 pullers. They aren't too crazy of amp hogs.

Sounds like the timing got changed and it burned the comm. can you send it in?

Ill check it out. Basically you need better low speed resolution on the controller, and more voltage.

[savage from the north]

Bought a very little used 7T puller (30 minutes),hooked it up in my Losi comp crawler,with a 13 t pinion.Was applying some throttle with the wheels in the air,and after approx 30 seconds or so,it started to get hot.I could hold my fingers on it,but not for another 30 seconds i think.
Pulled the motor out of the truck and ran it on the workbench,and it still gets hot.The esc did not get much heat.

Get any idea what the problem might be ?

I run it with Mamba max esc,11,1 volt lipo (25c).dx3r.

[JohnRobHolmes]

Is it throwing sparks? it will get hot with no load, so don't worry that it heats up on the bench.

[savage from the north]

Yes it does throw sparks,so maybe the timing is way off ?

[JohnRobHolmes]

yep. Check out the brushed motor thread at the top of this subforum for some checkpoints.

[Szczerba]

Edit, just saw your reply above....

Just saw this post.
My HH TMP 35t motor (Rear berg motor) is starting to throw sparks.
I smelt something last night, just tuning a new chassis and then a little punch to the throttle and I can see small arc sparks in the can.
When you hit the throttle hard. it will throw sparks from the can.

What did I do? I have about 10-15 packs on them.

[JohnRobHolmes]

The timing may have shifted a bit. A hard hit or just vibration can do it.
