Mr Homes;

Just wanted to let you know a LU 38 and a motor adaptor showed up at my house today.

I order 3 of these some time ago and received all 3. I think you may have sent this by accident. So if someone is missing there's I have it.

P.S. these are the only esc I would run in my crawlers I love mine.

Thanks
Dan W

Nice to see another "honest Abe" around Dan, just from the little hanging out we've done at the comps, you struck me as that kind of person

Hey JRH,

Can I run one of your 7t or 10t cobalts off of a Rooster Crawler with a 7.4v lipo?

Mamba max problem

I have a Mamba max with a crawlmaster 850 connected to it. Before hooking up my BEC it worked pretty dang good. Now for some reason, in a torque situation, (IE climbing up the side of my living room couch, lots of traction) the motor will squeal and squawk and seem to lose all torque. Normal driving up and down the driveway etc, it's fine. Seems to work great. But once you put the screws to it, it pisses out. WTF?

Any ideas?

hello, i had a question about my MM esc, ive been running a cheap cirrus tx and rx with my MM and it worked perfectly with no problems except that it is a cheap set up. I baught a airtronics mx-3s tx and rx and have had nothing but glichting with it. I did some trouble shooting, moved all wires away from rx, soldered caps on my motor , tried alot of different setting on tx but have had no luck. Just wandering if you could help. Thank you!!

John,
What's the latest on the 7t's? I ordered one a couple of weeks ago and was wondering about a time frame.

[Offroader5]

Hey John...
I was wondering if you've ever had an issue with running 9 cells on the M25? I have updated the firm and software to the newest and have it set up to run brushed. I have it wired up to a 55t Crawlmaster (from JP's) using the red and black leads.

I hooked up the pack (9 cell Elite's) and only after 5 minutes of bench testing while turning back and forth multiple times to test steering and only running it back and forth on the bench maybe a foot or so...the M25 was pretty hot to the touch. I hit it with the temp gauge and it read 210.

Knowing this thing is supposed to be alright up to 12 cells, what do you think the problem is? Could it be the new programming and running a brushed with it? Maybe all the bugs are not quite worked out yet? As far as I know, it doesn't matter which of the two wires I use to wire up the motor...or does it?

The address I would want it shipped i think is different than I think you have:

2185 south larsen parkway
Provo ut, 84606

Let me know

Thanks

Any update on this? I will send you the extra shipping when you let me know.

[Trimmy]

I was wondering when you were getting a new shipment of chargers in and when you could send me the difference between the 5i Dp and the 5I DP AC/DC so I can paypal you the money?

Thanks
Justin

[derwood21]

Hey John, I sent you a message through your website Sun. I think. Just wanted to check up and see what you can do. Want to get my order in before their gone.
Thanks,

[Bob K.]

I am excited to have been able to preorder the 10t. Now, my payment has been posted, does this mean it has been shipped? Will it work well with a Rooster Crawler ESC?

Thanks, man! Great thread, good stuff!

[JohnRobHolmes]

Being away this weekend put me behind in this thread! Lets get this going.

You have a paypal request for the balance. I shall make sure to ship it out asap so you get it friday at the latest. If your town is small it might take two days. Be sure to test the motor out before hopping into the comp, they are a lot more lively than what you are most likely used to.

Here is my setup...let me know your thoughts.

TXT
2 Hitec 5955tg Servos (4ws)
Mamba Max
Cobalt Puller 10T w/ RC4WD GRU
Spektrum
LiPo (Not sure # of cells yet)
Castle BEC

Last season I was having issue with the servos thermalling out. Going over all the geometry and making sure it is smooth.

Here is my question.

1. When I wire the BEC...do I tap it off the ESC Power Lead, like I did the Regulator?
2. Should I run one for each servo?
3. What LiPo would you suggest for this set up?
4. What voltage can I push the BEC up to without frying the RX or Servos?

Let me know your thoughts.

Thanks
John

1. Yes
2. Probably not needed, but these robot servos can really draw a lot so you might need it depending on the terrain and driving.
3. I suggest a big lipo, something with 60 to 100 amps burst and 3 cell. How much space do you have?
4. I have ran my 5955s on 7.4v with no issues, but if you say you have been having overheating problems that might not be a good idea. 6.5v is safer and still pretty peppy.

Thanks
Justin

Sidewinder does have 4mm connectors. On a sensorless bl motor you will give up low speed throttle for wheelspeed every time. The crawlmaster is pretty slow, but still close to a 50t in speed. You could always use a 3 cell lipo or 10cell nimh for more wheelspeed too.

Thanks for the honesty! I haven't been able to find where it should have gone, can you give me the postage date on it and if there is an invoice in the package?

I certainly agree!

Sounds like your battery could be getting low, but that is very strange. When you remove the BEC all goes back to normal?

What kind of glitchng? Erratic throttle, does it move when you are not telling it to? Does it only glitch under throttle?

Just got a call from the machinist today, they are done and I will pick them up tomorrow afternoon and start reassembling them and shipping them out. I have about 60 backordered so it will take a few days to get them all out I am thinking. Good thing I have most of Friday for nothing but shipping.

A 540 motor is a LOT to ask of the m25. It will get hot using that motor, probably even on 6 cells. If you want to run 9 I suggest a sidewinder or similar.

Just got one in today, I haven't forgotten about you. I will send that email in a few minutes.

Thanks,

I will check it out, you should get an email this evening. If not please post back up tomorrow with your question or send another email.


Thanks for the questions guys!

JRH

[derwood21]

Sounds good. Thanks

[glondark]

WOW Dude way to catch up on a thread! If I take the BEC off all goes back to normal. WEIRD! I have another battery and an Revolver coming tomorrow. Hopefully I can narrow it down.

[JohnRobHolmes]

Sounds like the BEC may be dropping out (voltage drop). Otherwise it could be causing interferance. It is obviously the issue, when indeed it should be a solution. Do you have a friend with one or have another one to swap out with?

[montereycrawler]

Thanks, can't wait.

I don't actually. Plus I need to wire it in with a plug instead of soldering it inline. I could take it back to CKRC (hahahahaha Like that is gonna happen) But I think i'll have better luck buying another one from you and swapping it in. Thanks for the advice mine, hopefully I can get it figured it out by this weekend.

[ruck"n"roll]

only gliches under throttle.

[ruck"n"roll]

sorry no, it glitches every once in a while without throttle but mostly with.

[JohnRobHolmes]

Try increasing the deadband on the mamba max, see if that changes anything. Otherwise it sounds like the BEC isn't playing nice with your radio.
