I watched a video on it with the 3px or whatever radio and it will probably worked like it, which seemed easy. Anyways I appreciate the help.

My time is pinched lately. I have a bunch of other videos I need to do. Since crawlers don't use this function I really haven't ever explored it. I'll see what I can do though.

Harley, here's one for you. I installed the Axial dig on my wraith. Seems to work great but when I want to lock my real wheels I can hear the servo click then no throttle. I have changed it to every DT and switch on the 4PL. With the same results. Is there a setting some where I am missing? The travel on the screen does not move at all, forwards or reverse. I set the DT to 100 per push so it should be like a 3p switch. I also tried it in 2p with the same result
Thanks,
Vince

Switch to a new fresh model. Sounds like you have another setting active.

Leave it to you to try something I didn't think of. Thanks

Ok I changed it to a fresh model. I set DT 4 to ch4 and set my end points so the servo won't buzz and burn out. Still having the same issue. The switch goes to D100 and I loose throttle from the display. The truck will not drive, and all the electronics seem to work. I eventually want to run 4WS and the manual states that ch3 is the slave for this function. So changing the model didn't seem to work which tells me the radio is the culprit. Harley can you get me a tech support number I can call?
Thanks,
Vince.

I honestly dont know the number, I've never called it.

It just sounds like you have some mix activated or something. I'm confused as well.

Ok I'll get the info off the web page. I did some more work on the radio. This is what I found out. Chanel 4 when made to have travel to D100 will kill the throttle, regardless of the DT/SW used to get it there. Maybe it's a software glitch. So I changed ch4 to ch3 to run the dig servo. With that the radio will show travel for the throttle with ch3 in all three positions. So it looks like I won't be running rear steering after all. I hope this helps somebody else.

Just set up my 4pl for the first time. Dual FXRs and CC BEC. Throttle is reversed - forward on the trigger both motors go backward. I reverse the throttle on the radio and only the front motor reverses, not the rear. Can't seem to find a setting to reverse the rear. I know I can flip the motor wires, but is there a way to do it on the radio?

Reverse the channel your rear motor is on...

Ch 4, reverse.

[new2it]

That did it. I knew there was a simple answer and I knew you would know it. Thx Harley!

Ok, call me a dummy, but my screen goes blank, everything works, but I can't see anything to use the display. Are these super sensitive to sun or heat. I never just leave it in the open sun, I find shade to lay it down, and I always make sure the screen does not sit in direct sunlight. Today I went to practice, it was hot and humid and sure enough my screen was blank. After about 10min in the shade it finally became visible. That remote was never over 88*. I took it from my garage, to my truck, drove 10min to comp spot with ac going, then got out and screen was blank. Is something week in my remote, or is it just super sensitive.

You can turn the contrast up, it's in the system menu I think.

[Tgreer]

You really think its just the contrast, I will turn it up and see if that helps.

What screen do you leave up while you crawl with the 4pl? I was using the default but found I like the dual ESC screen so I can see where I have the rear bias. Just curious...

A curious question.
When setting to S-FHSS and "High" speed, will this work with the FXR ESC's?
RX is R2104GF and BLS157HV servo on 7.4V.

FXR - yes
FXR Pro - No.

Yes, it's more for digital servos. The esc is fine in h mode.

Hello, I bought 4PL with code starts with B10, Have I update my radio to new firmware?

It's all on Page 1.

[vrkal]

I know, I´ve found it, but I just wanted to verify that it only applies to B010 or B011. So, that all other codes are OK except B010 and B011, if I understood.
