I am having some trouble with my hobbywing program box as well. I have 2 Justock esc's and a Xtreme Stock. They are all recently purchased (within a month). I also bought a 3 in 1 program box as well.
The problem is using the program box to make adjustments to the speed controllers. When I plug the esc into the program box, I can barely see the characters being produced on the screen. If the box is tilted at an extreme angle I can barely make out the "ghost letters" on the screen. I managed to get one speedo up and running enough to compete in a race, but I would like to do some further fine tuning.
Has anyone else experienced this issue, or have any idea how to remedy the problem??
Thanks...
