4PK Setups, Tips, Tricks and Help

[helhedded]

Ever since switching to the 4pk and a dual esc set-up I have noticed that when I dig on a vertical I get a slight rollback on my rear axle.


my setup on my 5.5lb truck:

4pk
HH 40t Epic motors
Dual FXRs
850 mah 3s 45c lipos


I run a "correct" gear mesh front and back. I know that tightening my mesh would probably help some, but is there anything else that I can do? I don't like running a tight gear mesh. This annoying rollback has cost me a few reverse penalties.

Sounds like it's most likely a motor issue. I don't even run my FXR's at full drag brake because they lock so hard. As a motor wears it will have a less effective drag brake. Might want to hit up JRH and get his oppinion on this. Running a tighter mesh is not a method I ever suggest, seams like B.S. fix to me.

Just got my xr10, also, i just got my first futaba radio. It's the 4pk with with the r604fs receiver, could you please help me get the correct setup? i'll be running 2) fx-r esc's, 2) 35 turn brushed motors, cc10amp bec, hitec 7980th steering servo. I also plan to take advantage of the cutting brake when it comes out. I've been reading you'r threads but still not real clear on the setup, wiring schematics. Please help Thanks.

For now you can use the wiring diagram I have posted. I will get a diagram added for use with the cutting brakes soon.

THX...that will work..

how about the ESC question..some help please

[Harley]

Sorry didn't see the edit. You need to add the expo in the ESC programming.

Thank you for your time...

My local Hobbytown had one in stock that is where I first saw it. Did you check tower?

I just got my xr10 the other week and got the chasis together. Its gonna be me first electronics build I've ever done on an rc, so I was nervous as could be trying to make sence of everything. This thread has been a life saver, now I know how to wire dual ESCs and program the 4pk. So now I can do it all right the first time

Hey Harley I am running dual fxr's in my xr-10 with a 4pks. I have the drag brake on the fxr's at 100% but on high traction sufaces it does'nt hold. Are there any adjustments in the 4pks that would help the drag brake?

There is nothing else your radio can do. Sounds like you need better motors.

They are team brood 45t le motors. I thought they were good?

[samaruki]

I have 45t motors and for me heaver brush springs did help with braking...

Hello

I have a AXIAL XR-10 with a NOVAK ROOSTER CRAWLER ESC and a PUNK 3 Dig.
I only want steer in the front wheels.
Can someone tell me how to put the 4PK so that I can use the Dig in the front or rear wheels?
I don´t see any button on the 4PK that has 3 positions:
1 position -Activate the front did
2 position -OFF the front dig, so put the rig in 4WD
3 position -Activate rear dig

Thank you

Brood motors are good, but you need to keep an eye on the condition of the brushes and comm. If they are brand new, more than likely the brushes still need to seat in. If they are old, you probably need to cut the comm. Heavier brush springs help too.
