Mamba Max Problem

[BL-Power]

I've got a problem with my MM ESC: When i wanted to go bashing this morning and i connected my battery to my Mamba Max, the 3 leds were flashing permanently and the "ring"-tone occured only one time instead of two times as normal. Everything is connected correctly, the BEC is disassembled and i'm using a 5-Cell battery pack instead. The Mamba Max just continues flashing its leds when i go on the throttle but steering servo in working perfectly.
Can anyone tell me what's wrong and how i can fix the problem!?

what batteries are you using? Is this a new mamba max? might be the overvoltage protection kicking in.

I bought it from skellyo and he told me that it's and old style Mamba Max. I am using 4s Polyquest Lipos, i ran the same setup about 20 times without problems!?

ok I'm wrong then.. lol just a thought. Not really sure.

hey, myn does the same crap...what i do is just hook the BEC back up if you unhooked your BEc wire.....i hook myn back up and run it and then unhook it and finally it will work...also my batterys arent that good niether...if i only plug one 1500 Mah NiMH battery it will just flash...but if i hook up both of my batterys it will turn on

Dumb question but.... are the batteries charged? Could it be the low voltage protection sensing that the voltage is to low and not letting you run?

[BL-Power]

The batteries are charged to 15,5V and the Lipo cutoff is set to 12V. The problem is also existing when i use my CC UBEC, so i don't think that the problem are the RX batteries

is your radio throttle centered? If you arent in the neutral position some ESCs have a fasty built in so they dont just runn off on you when powered on and the throttle isnt at neutral.

If you not sure you could try seting your radio trims and EPAs to 0 and recalibrate the esc to the radio. its possible there is something out of adjustment that the esc doesnt like.

[BL-Power]

The radio throttle is centered, everything is ok. Tomorrow my cousin is visiting me, i'll try if the MM works with his 2,4GHZ Futaba radio.

try redoing the radio calibration on the MM. It cant hurt.

[BL-Power]

I can't calibrate it, it is just doing the same damned flashing if i switch it on with full throttle.

[jhautz]

check to see if it is plugged into the rx properly or if there is a loose connection somewhere? Maybe is not seeing the receiver and therefore not arming all of the way.

The MM will not work when the radio voltage is not the same as the bec voltage inside the MM. The MM uses it's own bec to run the circuit board so the radio voltage has to match it or it doesn't recognize the signal.
