My 1st MAMBA MAXX ?
 

I just got my mambamaxx speed control fro mike. It comes with 4mm plugs, can i change them out for 5mm plugs for my 7XL with out voiding my warranty ?.

I have heard them tell members in other posts it is ok to cut the connectors off and solder the wires directly so different plugs should not be an issue.

While you're at it, shorten the wires if possible. They are kinda long considering they are only 14GA.

Actually, I think I remember reading in the manual that it was perfectly acceptable to do so...

Brian i already planed on cutting them as short as possible. The wires on mine are 13g not 14g. I also plan on using deans plugs on the batterys. If i decide to run 14 cells instead of LIPO's, i assume i can make a jumper of the speedo so i can use two packs , like you would do on a BK warrior ?.

Let us know how it works out.

Hope you like it as much as i do. I run a 9XL on my Mamba with a G2R and 12 cells

Isn't that a bit slow? Not criticising you or anything, just with a 7XL on 12 cells it was only a bit quicker than stock.

The 9xl has a kv around 1650. The titans are about 1200 kv.
I think he is running almost stock gearing. But then again he is a racer and to
much speed is bad as well as good.

Yeah, I'm currently running 17/66 gearing 32pitch. Its slow on flatland, maybe faster than stock, about 30 tops. Like coolhand said, I'm a racer and do most of my running on the track, the power and acceleration are a little better than a nitro but not uncontrolable and its a little slower top-out wise, but if setup right you're not going to top-out except on the straight

Hi everybody


My ubec should be here this weekend. Can i solder it to the speed control wires at the circut board were the power wire connects the the MAMBA MAXX, or do i have to solder it at the plug ?.

Well, it would be the smartest to solder onto the plug..

when you solder on the board directly, you need to heat it entirely, otherwise you'll get a cold connection..

Okay rene, i was just trying to keep the wire as short as possible. What if i solder it to the WIRE just before the board but not the acctual board ?.

Yeah, i understand what you mean..

If you just make it hot enough, it would be a good connection, but you need to pay close attention on the other side of the circuitboard, to see if the tin is melting on that side too..

While you are at it, you might as well put the output of the UBEC directly on escs receiver wire I was planning on doing that with my mamba-maxx. What bec did you get? i got one with a very small footprint, which would blend right in..

Rene i got the one mike sells, the UBEC. What is the benifit of putting the ubec output wires directly to th ESC reciver wire versus plugging it into the reciver ?.

big ass ubec.

It's what he had. :eek: It's still lighter & smaller than a reciver pack .

I soldered leads for my ubecs right at the circuit board. I put them on the underside of the board with a connector so the ubec can be easily removed.

One tip to make this easier.... scrape or scuff the spot you solder to and check to see if the solder gets good contact, not a cold joint like Serum said, before you solder the wire s to it. Castle uses a clear coating on the MM and it can give you trouble trying to solder, so that's why I say to scrape it first... wire brush, exacto, etc...

Thank you rene & glassdoctor for the tips :027: .

I'm getting ready to hook up my UBEC to my MAMBA MAXX speed control. My ? is the manuel that came with the ubec says theres two ways i can hook it up. The first way hook it to the (input power source) then plug it into the reciver, this way the system will be hot when i hook up the power source. The second way is to hook it up to the (input power source) then hook up a inline switch then plug it into the reciver. The way i was going to hook it up is solder it to the power wires at the circut board then plug it into the reciver. So if i hook it up my way will the ubec still be hot when the power is hooked up or will the switch from the speedo cut the power to the ubec when it's in the off postion ?.

If you disable the internal bec. I am not sure on the mamba either.
The quark has to be turned on to work. The esc switch. The rx will
not come up until you turn the other switch on.

I would like to know how is the setup on the MM max as it comes out of the box ?. Is it safe to run 14 cells on this setup or do i need to mess with the programing at all ?.

People have run the MM right out of the box, but I think they found that they would like to program from that point as it gave too much power.

You need to use either a UBEC or receiver pack and disable the controller's BEC, though.

Yeah i run 12 cells and need a UBEC or reciever packHaven't tryed the switch yet though

WOW! 1400 posts, Who thought i'd have that much to say

I would! LOL!!!!!!!!!:005:

Yes metal man i will be using a UBEC with my 14 3800 cells. I was just wondering how the stock setup is. I thought i might try it first before reprograming it .

I need help :005: .

I'm trying tp program my mamba max with no success. First im using 14 cells my ubec is connected at the circut board with a inline switch at the reciver, & the on board bec disconected. When i turn my esc while holding the trigger on my radio it beeps 4 times all the lights blink & i have no power at my steering servo. So how can i tell if my ubec is working

After the full throttle, pull back to full brake. wait for the beeps, then go to neutral. It will arm from there.

I took the switch of the UBEC & it works. My next ? is to adjust how fast the power comes on am i better off adjusting the exp on my radio or reprogram my speedo ?.

Glad you got it going hippie. Sorry I couldn't help you more on phone.

Hook up your mamba-maxx to the computer via the USB cable.. It programms like nothing else.

So easy you won't want to run anything else

UBEC wires melted with 4S Lipos
 

Guys, I just ran my 4S setup and my UBEC wires melted, I thought it was a fluke, re-wired and it ran slow after a full charge an the same thing happened again. My setup is MMax with feigao 7xl motor, I ran my UBEC input wires straight from the 14V Lipos and the neg wire keeps frying. anyone see this B4?:035:

Welcome to the forums ;

That is odd, why not try putting the UBEC positive to the esc positive and UBEC negative to the the esc negative.

It may be that when you hook the batts up.
You are touching the red wire first. That would let the ubec be the ground.
I can't tell much by photo. Wires are everywhere.

Welcome to the forum though.

UBEC wires melted with 4S Lipos
 

Thanks Sylvester, I think that's what I've done, the UBEC pos and neg are soldered to the battery pack pos and neg and they are connected to the ESC input Pos and neg, I'll try soldering them straight to the ESC input wires in case I have a bad connection, but somethings drawing way to much current, check our my neg wire.

That doesnt look too good. Try just connecting them to the esc main wires and try again. BTW, what UBEC is that? If that isnt working too well maybe try the one mike sells.

Believe it or not it doesn't say who makes it, a friend gave it to me, it just says 3A switch mode UBEC, I can't read the japanese, it still works though.

Well, if the problem persists, Id try a UBEC off mike, it should work flawlessly.

have you got rid of the red wire in the rx wire to the rx off the mm.
