Default Mamba 25

I have a issue with the mamba 25 and a 1050kv brushless set up, running thunder power 2 cell lipo.................. No matter what settings I use it still seems to stall on a test climb up the wall unless I use lots of throttle. I cant seem to creep up it at all.

Using a 12 tooth pinion 87 psur and a t-3 trans with tlt axles

Settings are ....high start....0 timing...low something (cant remember,brain fart) 0 drag brake this seems to be the best but buy far not perfect or even goodfor that matter.


What elso should I try ?

Found this in the brushless sticky:

Do you have the Castle Link? If so, load that profile and see if that helps. It's the default profile that JRH loads on to each ESC he ships out.

If that doesnt work, call and email Castle to ask advice on it. It sounds as though the mamba 25 wont hold the high pole count motor in one spot. They could adjust the programming a bit to suit us rockcrawlers. ;) ;)


My second guess is that your motor is too small for the vehicle and it is constantly stalling out at a creep. What motor is it exactly?

My third guess is that the Lipo isnt keeping it's voltage under load, and the motor is stalling out because of that. Do you have any 2/3 A cells to test with?

it's a 400 motor? You definitely need to be running a 3 cell LiPo for the 400 parkflyer size motors. 7.2/7.4v is not enough especially with that high of KV motor.

Gearing is fine. Maybe can go to a 90T spur for a little more help.

Yes it is a 400 series motor, the one cheap battery packs and tammies are selling. I think they call it a elite not an eflite. I tried my 3 cell lipo a few minutes ago and it was a little better but still not good,and the mamba got real hot in about 2 minutes of testing on the wall. Really good wheel speed with the 3 cell.

thanks for the help,any other suggestions

I played with the casle link at the lhs because I cant get the thing to work on my computor,castle's download is for the pheonix not the mamba but if I read it correctly that is a v2.2 and should work with the mamba. It loads fine as does the driver for the usb but as soon as I hook up the esc it reads it then freezes nothing can be adjusted . I cant even close the window.

I tried several battery 2/3 packs 6 cell and 8 cell thinking the same thing about the load,all had the same results.3 cell lipo was better but still not good

The truck is a bmv2 chassis and is very light

I will call castle on monday and see what they have to say

Any other ideas,comp is tommorrow and I would like it to shine

Thanks for the help

I am not aware of the pheonix programming being compatable with the mamba controllers. The USB interface works for all controllers though.

that was the only down load on the site, I will check again

Do you have a link to the download for the mamba.

scroll alllll the waaaay to the bottom of the page...

And that crawler profile I linked earlier doesn't have to entered manually. Just save that file to your computer, fire up the Castle Link software and then click File > Load Settings and browse for that file.
