Radio Kits
Think I have one, was going to use it for my yacht, but haven't got round to it. Other than that.
With all 2.4's, always keep the bind plug handy. I've had a few cases when they have "un binbed". I then spend ages checking everything else, then the penny drops. Something else I've found with mine, is the range isn't as good 27 or 40 Meg. it's a known problem with water, signal can bounce off it I gather. Therefore no good for subs. I mount mine as high as I can in the Model.
