You need to program both FXR's at the exact same time. Also you need to make sure that your gear mesh in your axles aren't too tight. There are several things that have nothing to do with the radio or ESC that can cause your delay.
 
So when are you going to update the wiring diagram ?

I need to get my truck done soon.
 
As far wiring goes, nothing has changed with the new way ? what did change was what slot you plug what in correct ?

You use channels 2 & 3 instead of 3 & 4.

Exactly. You can just plug your BEC into channel 4 now instead of 2. I am going to a diagram though that shows how to wire it if you are going to add something to channel 4, such as winch down or cutting brakes 8)

One more dumb question, Do I need to pull both red wires on both the esc's for the bec ? I don't plan wiring the bec direct to steering servo.

I don't recommend having control over the front mix for two reason. You can overdrive with the rear pmix and it is another setting that you have to center while driving. On course this means lost time. I have not found it needed to overdrive more than the 20% which the rear mix is capable of. This is something that comes from putting tons of hours on my rig. It may seem like something that is nice to have, and you may even use it in practice, but when you are on time and under pressure it is just going to cause problems.

With more time on this, I still like the ESC's on ch. 3 and 4. The thing that I really like about this set up that I can't get with the recommended set up is the throttle expo. I am running brushless motors and the expo gives me much better control over them on the low end. I still get the speed when I want it, but the expo gives me a longer low end speed area on the throttle. Either way, this is an awesome radio!

With most speed controls that can be programmed directly as opposed to having to use the radio to do it.

True, but it is easier to adjust on the radio. I don't need to keep ch. 4 free for anything else, so this is a good set up for me, at least for now. I really appreciate all the info. I have found in this thread.

I also like having front and rear % control on the dials. I run them at 120% so I don't have to find 100% and just back whichever one I want down. It is easy to just roll the dial back to 120%. Rolling the rear back to 50-20 also works like a freewheel dig. I have had occasion to use less than 80% front too.
The new setup is great to free up the 4th channel though!
