4PK Setups, Tips, Tricks and Help

[Erik D_lux]

So I went back through and set everything up just like your vid....it's working great right now...but I gotta ask you guys..
Don't you ever feel like you need to overdrive the rear esc more then 120%?? When my rig is on a climb and all the weight transfers to the rear and clod stall comes in 120% does not make the stall go away the front still spins fast and the rear still stalls..... I just feel like turning down the front esc would work much better to get both axles moving at the same time....
Can't believe I'm the only one who feels this way?

If you need more, you can calibrate your ESC when your radio is at say, 80 instead of 100 on the rear motor through mixing. This will then act like 140 vs 120. At least thats how it worked on my 4pl. I used to calibrate my ESC while at 85 or so on the rear motor. That made 120 just a bit too much, just the way I like it.

That's kind of a bandaid as all it does is make the throttle curve steeper for the rear and take away fidelity in the trigger under normal driving. It will kind of work but not my suggestion to do as such.

Is there a better way?

Like 53 said, we have found a couple of climbs that can be impossible without the rear severely over driven.

So I swapped esc channels and everything is now running just how I like....already making climbs I could not make when set up the other way...
Thanks for all the help Josh

You need to run yours like mine...

I take that as an insult and a challenge!

See you tomorrow, sucka!

Did you ever get a chance to look at the 4ws mixing option on your 4PKS?

I did.

You need to move the rear ESC to channel 4 and one dig has to be moved to PS3 (up top). Not handy but works ok for rear dig since its les used.

Rear servo goes in ch3 and the steering mix goes onto PS2. Works pretty well. Easy setup.

 

[Scottmisfits]

Awesome. That should sort it all out. Thanks Harley

Small "issue" that I ran across with my 4PKS a few days ago.

I'm attempting to set up 4ws and a winch on a rig of mine and am having issues with channel 4 slaving channel 3 when activated.

I went in and used the 4WS setup option through the screen and set it up according to a tutorial.

I have the 4WS set up on PS2 with the winch on DT3. As far as I can tell, I have no other functions tied to any other switches or any other mixes activated.

When I activate 4WS on its own, it works how it's supposed to activating only channel 3.

When I activate the winch on it's own, it works properly only activating channel 4.

When I activate the winch when the 4WS is activated (or 4WS is activated during winch use), it kicks the rear steering to 100% travel in the direction that the winch activates.

Whats odd is that when the steering is held to full lock by the winch control, the front steering works normally, yet the rear steer channel neutral got shifted to the new position. Rear steer will only add to the new neutral position, yet will not go anywhere less than the new neutral. It will not go anywhere less than 100% travel, yet will sit at 100% and add to it (100%+). Make sense?

Any ideas on what I ended up missing?

Few local guys I showed this to didn't have any ideas.

Has anyone been able to duplicate the issues that I've been battling with?

I can't find any mixes that are turned on or any good reason why channel 3 is slaved to channel four with the 4WS option enabled.

4pks with Tamiya Highlift

sorry if this was already answered but I'm new to crawling and I was wondering if anyone is running their Highlift (I have the Tundra) with their 4pks?
I was able to get ir running but looks like it's only shifting 2 gears.

I have it set up with my ps2 button and like I mentioned I am able to get 2 gears.

again sorry if this is an old question but thought I'd give it a shot.

thanx

First post has a link to how to program a 3 position switch. You must shift with one of the DT's.

Are you guys tucking the antenna wire in the receiver case or just making a small coil and using a ziptie to secure it close to the Receiver

I have always just taken mine off.

Multiple ways to do it, it kills your range, then again, in crawling you're usually never too far away from the rig."thumbsup" I never cut them since I may want to use the RX in a go fast at some point.

You should never cut them but the nice thing with Futaba RX's is they are a coaxial plug right onto the board so they snap on and off.

I take mine off most of the time too.

how to set winch to become forward-neutral-backward in futaba 4pk , becau se i saw in page 1 the settings is only can go forward and backward.. thx

 

[Erik D_lux]

I cannot figure out why on my super I have to switch the "TH" and "CH3" settings reversed of my Berg?? The bars go to the left on the main screen and on the Berg they go to the right.

As far as I can tell my motor end bells have the same orientation from car to car, ESCs are all sidewinders and set to "normal" rotation. The only difference from car to car is one has Holmes motors, one has Brood and the super uses the "C2" mode where as the Berg uses the "C1" mode.

Any suggestions?

What channels are you using for your ESC's on both rigs? 2 & 3 on both? I can't really tell you why without seeing what you programmed.

Have you checked if you have your channels reversed? Sidewinders are showing green LED's in forward throttle? Endbell may be rotated 180. What is your super? Super Berg? Bully? Does a bully have an extra gear like the XR that reverses the rotation?

 

[Erik D_lux]

Both cars are Bergs. Both have front axle in 2nd channel, rear in 3rd channel. 2.2 has a 3 channel, super a 4 channel RX.

I programmed my radio on both models per your video, they should be the same.

I cannot see the LED's on the sidewinders since I have both cars shrunk down and covered in black shrink wrap. As posted above, in the castle software all 4 read that they are running in "normal" rotation.

End bells look the same on both cars. I thought this was the problem in the first place but after much research, I dont think so.
