I've got one and I "thought" I had issues with the steering (not enuf throw). Turns out it was the 3rd dial on the controller that I needed to adjust. LOL

I think the only issue this radio really has is not having a proper manual. Got everything figured out on here though.

Spektrum radios however, do have frequency issues.
There is this area in a parking lot near where I live, where NO Spektrum radios work. Its so weird that once you cross over this line (in the parking lot) Spektrums stop working. I've only noticed this with Spektrum nothing else - it was a guy flying a rc-heli with the spektrum system.

My traxxas Link works fine, so does the XP3-SS and the MX3-FG and of course the FS GT-2.
We have ruled out interference from our radios, but we don't know if its maybe something else in the facility that is causing the issue.
