Mamba Monster cutting out at full throttle.....

"CAN" popping, as in the KB45's skipped over its threads even though I had used JB weld on the end bell threads. It popped over the threads 4 times and the last time finally finished her off. Next time I buy a KB motor I am going to make a motor clamp for it similar to the rc-monster feigao clamp.

I have a few 7xl setups and they can draw some juice. I use trakpower lipos and they can keep up, but with only 4900mah, runtimes are short, like 15min with hard bashing.

I did adjust my throttle trim on my radio after I progamed the esc. Maybe it just needs to rearm with my radio / settings? Maybe when I go to full throttle the esc is seeing it as nothing because the trigger is moving to far or something, I dont know. But my temps arent getting very hot with this gearing.

that is what the calibration is for! Calibrate the ESC and then you know it is not cutting out because of this.
To calibrate the esc to your radio
turn on radio
hold radio full throttle
turn on ESC
it will beep then hold full brake
it will beep again
release to neutral
will beep again and then arm

THANKS!!!

I never did this calibrating like you described. Do I have to do this every time I turn on my esc / radio?

nope only once unless you change to a different radio down the line.

No, It saves the settings. You do need to calibrate the esc to your radio, even if it does arm without doing that.

Your gearing may be too tall and the battery voltage is falling enough to hit the lvc. I just mentioned the radio settings as I had that problem before.

If I change my throttle trim settings AFTER calibrating my radio & esc do I have to re-calibrate the esc / radio again???

just make sure your trim is at center BEFORE calibrating and all will be fine. Besides throttle trim should not be changed. If you had to change it to keep the truck from moving you DEFINITELY need to calibrate it. From what you say i really think calibrating will make a huge difference. If not well it wont hurt to calibrate it.

Yes.

Why would you want to change your trim after you are calibrated? I mean, that's what the calibration is for, after all.

Just set all trims/epa to default and leave them there. You'll have a much happier setup because of it.

Thanks, just wanted to know because sometimes I mess with my brake linkage / servo.

adjusting mechanical linkage will not affect the calibration but trim will.
In your case do this
get your brake servo mechanically as close as possible then trim the throttle to be PERFECT, make sure it is right BEFORE you calibrate. Once it is all good leave the trim where ever it is at then do the calibration.

Cool beans

Lunch time update....

I did the calibration thingy, it defiantly made it run smoother although I was still getting some random cutting in at out at full throttle. This could be due to this is the zippy lipo's first cycle, I will try my older pack when I get home from work. It defiantly appears as its the lvc which is causing the motor to shut off at full throttle.

good, yeah my maxamps pack takes a few to actually kick in at full voltage. at first it only goes like 1/4 power then it just hauls off into a backflip I think it is your batteries. Others say the gearing is tall but i run the same gearing and mine is perfectly fine, my truck also is very heavy (full alluminum) Oh and i do run the 8xl not the 7xl.
