(HH) Tech Questions and Customer support thread

[rcalhoun]

I have a 7 turn puller motor that needs a rebuild. I read on here that you do this i dont have a motor lathe and the people i do know i dont trust with it. I figure it is in better hands with you. just wanted to give you a heads up and waiting on a response from you before i send it. I know how hard it is going to school full time and balancing a full time job at the same time.

I am getting a traxxas summit and I would like to upgrade it with the dual Revolver 700-HO Motor Conversion. I would like to run this with 2 3s lipo batterys in series. I see that your ESC will handle a 6S battery but will it handle the 2 700 motors?
Do you have any suggestions on any other setup you might thing it can be more powerfull than this without going brushless???


Thanks

Im new to lipo and I just got a HH 1300 2s lipo and when i plug it in to my Hyperion EOSO6061 charger and start charging it, it starts at around 7.6 volts and continues to go up. The store mode also makes it go up. It seems my settings are right but im not positive

You should be fine with your current setup. I would run 6.6v on the regulator because of your receiver. Not sure what could cause those ESCs to lose throttle positions. Maybe a loose connection? Maybe you should update the firmware on them.

A rebuild is $10 plus parts assuming it is fixable.

That would probably be a good way to go. I have never used the 700 motors so I don't know how fast you can push the vehicle. You may need two ESCs to handle the load safely.

Tell kershaw thanks for not using the Revolver name for a crawler product I guess he didn't remember our gentlemen's agreement about it.

The pack will peak at 8.4v. No worries! Storage should be right around 7.4 to 7.6v.

JRH,
I got a question about the set-up for my 1/6 jeep scale build. I wanted to run your br-xl esc, waterproofed of course, a 10t puller, r2 heavy duty trans & a 3 or 4 cell lipo. Since your puller motors are hard to come by, what do you suggest? I am using 3.2 size rubbers, wheelbase is right at 17" long & 10" wide & the rig really isn't that heavy.

I have a couple of your original handwounds, a 35t & a 45t and was thinkin of running the 45t with a basic r2. I wanted to get your input on this before I place an order for all the goodies that'll make it move. I would like to have some good wheelspeed without sacrificing torque & also somethin I can run through mud, rain, snow, sleet, hail, or whatever else I may encounter.

Thanks for the help.

[JohnRobHolmes]

If it isn't that heavy, the 45t handwound on 4s would give you plenty of pep. If you will be thrashing the motor in water and mud, you should put a sleeve over it to keep the gunk out.

[gottorque]

when are the 33t Torqmaster minis gonna be in stock. I was gonna get one on my last order but they were out of stock. So i ran my new project on the stock motor and burnt it up its first day out. Now its just sitting

[JohnRobHolmes]

A few weeks, per the factory on Wednesday.

new setup:
HH BR-XL
Cobalt 14t

Will a 7 cell nimh elite 2/3A pack be enough to power this for any decent amount of time? Or should I be moving to a 3s-4s lipo? It will be going into an AX-10 based comp rig with dig. Airtronics MX-3FG is the radio just for some added info. Thanks!

[JohnRobHolmes]

You won't have a lot of power or punch with those packs. I would suggest a 1300 3s lipo instead.

[yjdavid]

that's about what I figured. thanks for that!

[cwettstain]

First, thanks for keeping up with this thread. You're definitely committed to your products!

I just bought a torquemaster br-xl esc for my ax10 with dig and 3s lipo. When I turn all the way in one direction, both servos and the throttle start "twitching". I adjusted my steering EPA down some and the problem went away. What does this sound like to you?

[JohnRobHolmes]

Sounds like the servo was hitting an endpoint and stalling out It wanted to go further, but the steering would not let it. When they stall out, all kinds of things can go wrong- from glitching to even losing signal. This could be a sign that the internal BEC is getting overloaded at that point as well, but it is not always the case. Running proper EPAs are key to long servo life especially.

[Knarly Nerd]

When using Castle Link to program the Torquemaster BR/XL, which product should be selected in the software or does it auto-select?

[JohnRobHolmes]

It auto selects

[yjdavid]

I installed the br-xl and the puller, still with the 7cell 2/3A ni-mh pack.

Thing has NO power (my sidewinder/novak 55t was faster and had more torque), super slow, will barely push the tires up a wall if i drive straight into it.

rig is geared 87/14. and has low gearing in the axles.

I think this battery pack may have been dying before the install, does this sound like just a complete lack of power from the battery?
I checked gear mesh and drivetrain binding... everything seems cool. Any suggestions? I think I may be heading to the LHS to get some lipos and a charger??

[JohnRobHolmes]

Yep, that is your battery that is pooping out. Give a 1300 25c lipo or bigger a shot.

[yjdavid]

alright. I just wanted to make sure it didn't seem like something was up with the esc or motor. i've read that the 7t pullers get hot on 3s lipos, is it something to worry about? or will comp runs and like 20 minute practice sessions be a problem with it?

I just checked the two packs I have and they were both charged at 8.3 volts, but then when I ran them they gave maybe 30 seconds of sub-55t performance with this new setup. Just so I understand what's going on here with my limited circuits knowledge... This motor asks for 40 amps all the time, and the small nimh packs can't provide close to that, so it sucks all of their dying amperage out of them in seconds?

[JohnRobHolmes]

The 7t does get hot on 3s. It is ok for limited use, but you have to watch the heat carefully.

The issue with 2/3a cells is the internal resistance. When you ask too many amps, the voltage sags greatly. With no voltage you have no "pressure" to create a sizable amp draw. In general, you just can't get enough power from a 2/3a cell.

[yjdavid]

Would an external fan mounted somewhere around the motor help in any way? I suppose it would be best if it was run off a seperate power source all together even though I don't see how a small PC or similar fan could draw much current....?

Thanks for your always speedy replies!
