Viper RC -
blue, biggest thing you could try to do on your end is verify the radio signal is getting through. If you had a different speed control (even to just plug into the receiver and verify it works. As Cain said, typically that only one red P light is not a good sign. How it got that way.... couple of possibilities. But if you can plug another speed control into the receiver and everything works, it points in one direction. As you mentioned it needs a signal to complete start up.

Bob,
Biggest thing I have seen is that the speed control could be having an issue finding neutral on your radio. Each model on the radio sends out a little different signal. First thing I would try is to move throttle trim 2-3 steps in either direction and re-try the calibration.
The EPA setting for our system should be 100%, going higher can make the throttle and brake feel too soft because the throw becomes too long.
If you are still having the calibration issue after the throttle trim, you could try a different model or re-bind your receiver to transmitter. I have a 4pks radio and one of my radio models will not calibrate with the throttle at neutral, tried it with 4-5 speed controls. Move the trim slightly, no issue.
PM me if you have any other questions.

yeah seems the futabas like t "drift" alittle more.
Its much better I thought with the new A64 software. I had issues with the previous one I at times just had to unplug my battery for the system to accept a shutdown request.
Is this something that can be address Nick in a future software update? that if I am pressing the shutdown button to make it shutdown the system will shutdown regardless if it things its getting a transmitter "input" at all?

The "drift" is from the radio, not the speed control. So its more of a radio issue than ours. Not every radio is effected, it depends on how a particular transmitter is working. Under the Throttle setting you can change the deadband to make it wider, depending how band your signal drifts this could help correct it. But also realize your adding throw you need to complete with the trigger before the speed control reacts. This may effect some more than others.

We were having some self inflicted problems yesterday at Dalton Rc. We asked Brian Looper for some help and he was a class act. I really appreciate his help, and Viper should be proud to have drivers like this.
Since it looks like the entire product line is changing, I just wanted to add some of my personal preferences in any changes you may or may not make.
For the VTX8, make it run dual mode. i.e sensored/sensorless.
I absolutely love everything else about the ESC.
For the VF4 motors...
Please make a 4 pole 550 can Sensored, very few actually run 540 cans.
I understand you will make one for roar but we want a 550!!!
I had the Viper 4 pole 550 can Sensorless and it was an absolute beast!
For the VF8 Motors...
Make a Truggy Motor....
We don't need a whole lot of different Kv Choices. Just 2 really a 1900 and a 2100. Buggy and Truggy. Keep it Simple.
The 2700 was a poor decision imo.

yes to both of those.
Also, add in something like Tekin's push control for the VTX8.
And if the new ESC can be made smaller, that would be great as the Viper VTX8 in a Tekno ET48 is just too close to a truggy sized motor for my liking with where they sensor port is commonly (top of can). A slightly smaller ESC would fix that, or, a motor with the port coming out of the "side" of the can and the top so you could pick.

I guess I should of said more useful when somethings not right or the sytem just shuts down leaving you wondering. Being able to actually see bec voltage, battery voltage, esc temp, motor temp, rpm, tp, sensor check and whatever else is extremely useful.
