Mamba 25....Park 480 issues...cant get it to stop cogging

[rockwerks]

Try programming the start up with a different setting yet?

every combo available on the mamba...............it always acts just the same....Im thinking the Mamba is the bad part.

I guess I can try and build a 8.4V 2/3A pack and see if the extra punch will help:roll:

If my mamba ever gets back from castle i will try my stock losi mini-t pack. It should be of lesser quality but the same voltage as your intellect packs.

Do your packs have a good charge in them? Once my GP1100 pack starts getting low it has the same problem as you.

If you built the pack yourself you may try checking all of your sauder connections.

Im assuming they have a good charge, fresh off the peak charger.

As long as the pack has decent contruction, the packs should not be the culprit. I hesitate to say the mamba is bad. When they dont work properly, they usually dont work at all. If it aint the motor though, and it isnt the battery, the esc is the last one standing.

all I know is prgraming changes do nothing at all except for question 1, noting else is a noticable difference

my thought is that the 2/3a cells can't put out the needed 22A start up,

Im gonna build up a subC 3000 pack and see if that helps


This motor might just bee too much for what Im running

the park 400 that MG is running uses half the power

IM gonna build the bigger pack with higher amp output and see if that fixes it.

also I willl set all the radio defaults back to factory settings

and mamba to factory settings..........and start from there

 

[JohnRobHolmes]

IB 2/3 a cells will hold 30 amps continuous draw, and burst a bit more. Go ahead and build the pack though, it wont hurt anything to try something else.

how do the specs of the revolver rate up to the 2 park mototrs, I cant find where you have listed the amp draw specs

Continuous Current:

Max draw:

 

[JohnRobHolmes]

in all honesty I dont really know! I have never found specs, and have not had the chance to throw a multi meter at one. All I know is that the motor works in our applications.

From the size and wind of the motor, I would guess that it can take around 20 - 25 amps continuous and burst 40 amps for 10 seconds. I will check out the average amp draw asap.

 

[JohnRobHolmes]

edit: those amperages would be at 10 volts.

I think you are way off on those #s..........im betting more in the 12 -15 amp continious and 25 to 30 max.......

 

[JohnRobHolmes]

Probably, it is a short can. But the diameter is 28mm. Like I said, I dont really know!

FAWK IT!!! tired of messin with the 480. just sold it to a plane guy. for what I paid for it.........order is on the way......you can send me the plugs when they get in........ONE REVOLVER PLEASE!

 

[JohnRobHolmes]

sir yes sir.

 

[Cole82]

Should have got the Quark and revolver in the first place.8)

already got the mamba sitting here....

 

[rockwerks]

sir yes sir.

LMAO:lol:

 

[Cole82]

I tried the mamba too because it is laying around. Night and day differance when you can actually use throttle control. Like on the quark.

I can graph that how ever I wish with my radio. forward and reverrse seperately

 

[JohnRobHolmes]

the minimum motor rpm speed is lower with the quark esc. It is much quieter as well. Something in the programming. The Quark isnt as reliable on startup for me though.
