Mamba Max Pro help.

[arctichorse]

I just got my Mamba Max Pro and after programing it to what I want I took it out for a test drive and this happens, when I'm easing into the throttle just before I pull half way it all of a sudden releases this burst and it goes balls to the walls, this is a problem for rock crawling because when I'm on a rock and I need a bit more if I hit that point it releases this burst and my rig goes flying over the rocks at this high speed, I don't know what to look for in the programing section to make it an easy transition from 0% throttle to easing all the way too 100% if need be, with out it jumping to a higher speed at the half way point in my pull of the throttle.

Oh I'm running a Velineon 3500 Kv brushless motor, if anyone else has a mamba Max Pro if you don't mind can you tell me what settings you guys have? Thanks.

I hope this makes sense.

Here's a video. At 6 seconds it does it.

Have you programmed your radio to the ESC? Sounds like that needs to be done.

I recalibrated it to my controller, still doing it.

Set on 0% and it still does it.

If you connect a servo to the throttle channel, is it jumpy too?

[eagle1978]

mine was doing the same thing when I first got it as well, it ended up being my transmitter wasn't set right...

Nope, it doesn't act jumpy.

[chris4207]

What TX are you using?

[Twisted Nuts]

1: check your throttle curve (make sure it ramps up from the bottom left corner to the top right corner in a STRAIGHT line) , disable punch control 0%, set start power on high, these are just a few to check

The Traxxas 2.4gh receiver and radio.

What did you have set wrong, maybe mine is the same problem, thanks.

[eagle1978]

I have the futaba 3pmx and I cant remember exactly what the setting was but it had to do with the throttle curve on the transmitter side, once a friend dialed it down for me, I had never used this transmitter at this point, it was buttery smooth. I wish I had it here to tell you more, but I'm in VA and it's in MS right now.

[arctichorse]

Shoot, oh well, seems like my ESC just doesn't like low speed.

[arctichorse]

Do you guys think it could be the BEC going bad? I have variable speeds for each time I pull the throttle. Or could it be the radio? I'm using a Traxxas TQ 2.4gh radio.

Or it could be the simple fact you're running a non sensored Velineon motor on a crawler...

X2....I know there are people out there running the velineon setups in crawlers, but the one time I stuck a brushless castle motor in my rig it did a similar thing. It would cog badly If I tried to jump into the throttle to quickly, so I would ease in and them BAM off she went....off the table off the rocks off the well you get the point. If you go full throttle from a dead stop, does it sit there a sort of twitch ?

Nope, no twitching, cogging, jumping, nothing out of the ordinary, nothing to tell what the heck is wrong.

I was wondering that myself but even sensorless shouldn't have this problem, it could be the firmware because when I down loaded the 1.26 version this morning and my problem went away.

[arctichorse]

Problem fixed, it was the 1.30 firmware update for me, I down graded the firmware to the 1.26 update and it works perfectly now.
