The connectors good, what's the polarity?

If you open the battery compartment you will see three (3) pins, the middle pin is +ve, whereas the left and right pins are -ve, assume your lipo pack comes with a three (3) pins female plug, with the center pin wire to +ve of the lipo pack, you can actually plug it into your M11x anyway you want without worried about wrong polarity. So, again in:

1) - + . or
2) . + -

"." = No pin
"+" = positive
"-" = negative

Now, here's the tricky part, SOME lipo packs comes with a two (2) pins female plug, one wired to +ve and one wired to -ve (obviously), so when you plug it in MAKE SURE you plug in the POSITIVE of the battery to the MIDDLE PIN in the M11x. With a two (2) pins female plug you can accidentally plug in the wrong way and fried the radio. If you happen to have a lipo pack that came with a two pins female plug, I suggest you change the plug out to a three pins female plug for added safety.

I have a problem with my 451 receiver, after about one lap of the track it seems to be draining a brand new recharged battery pack, servos have trouble turning. if i discount the battery and reconnect then everything is back to normal and back to full movement of servos etc, but this only lasts for say 30 seconds or some before the servos have trouble turning again.

i've ran the same servo combination with this receiver previously with no issues and have eliminated the servo as a source of problem as I have tried different servos.

has anyone encountered anything simialr?

i have also ruled out the battery packs because i've tried 3 different packs from 2 different chargers.

does anyone where to send airtronics for warranty repairs?

What servos and battery pack are you running?

Try to rebind the receiver again.

i just found the problem, it was a bad switch.

thanks

Glad to hear that it is only something minor... :sweat:

:nod::lol:

Just gt my M11X and im new to a radio with soo many features..im kinda confused witht he EPA and Dual Rate...should i set my steering endpoint with the dual rate first or adjust the EPA for them?? Thanks!!

This is my work flow:

Adjust steering linkages -> adjust dual rate -> set EPA

All the best! :nod:

anyone know how to operate the 3rd channel of m11x?

thanks

Ah Chu,

The 3rd and 4th channel is for mixing, say if your car have independent front and rear brakes, then you will use the 3rd and 4th channel as front and rear brake. You can mix it in following ways (from the manual):

1) Channel 2: throttle and rear brake, channel 3: front brake, so when you apply brake, rear brake will be controlled by channel 2 and front brake by channel 3

2) Channel 2: throttle only, channel 3: front brake, channel 4 rear brake. You can mix it in such a way that say you want the rear brake (channel 4) to engage first before engaging the front brake (channel 3) , i.e. delay.

Ok 1 more question and im on the track..is there a place to set the servo frame rate or does it just defult based on servo

For me it is: Steering linkages -> set EPA

Is it just me? I usually leave my dual rate at 100%, but if I somehow need less steering, I'll turn down my dual rate.

+1...I follow the same practice.

For me, I set my linkages then set the dual rate to make sure my steering travel does not bind either turning left or right. Dual rate affects both left and right EQUALLY (assuming the linkages are set equally on both sides). IIRC, my current dual rate is at 70+%.

Actually, the manual explains it well. If your car oversteer or understeer, you can increase or decrease steering by using Dual Rate, and you won't have to adjust Left travel and Right travel individually. Plus you can adjust it while you are driving with the programmed TRM switch. If you use EPA to correct over or understeer, you will have to go through the menu and set left and right travel individually which can be extra finicky if you are in a race situation.

After setting the Dual Rate, I will then set the EPA for left and right travel individually while the car is still on a stand.

I will then set the TRIM while actually driving the car.

So, for me:

Linkages -> Dual Rate -> EPA -> Trim

One can always skip the Dual Rate and go directly into setting the EPA. In the old days of two sticks radio, I set my linkages then straight head to the track and set the trim, there weren't such thing as Dual Rate or EPA during those years... :blush:
