Tom, what Rx are you using? Also ... over what time period is Spektrum saying fix it if over 500?? Are they talking on a 10 min flight or a 1 min range test?
If you need them, I have a few aero shaped fins that can house the tip of the satellite Rx antenna so it looks nicer than a wire sticking out. Wish I had known this past weekend and I would have given them to you. I'll be in your area next week and can leave them with some of your crew to give to you.
