Sorry about this seems the only time I come here is with problems. I have a bit of a puzzler. I purchased an Spectrum AR6115e rx for my heli build. I know it is not a full rang receiver but I though it would be okay to use to learn to hover a heli. Well long story short. Plugged it into the bec power supply and started run up to see if things were working. It worked for about 20 seconds before unbinding. It then refused to bind at all. Just get a slow blinking orange led. I then tried it on an older 4.8volt rx supply and it binds almost immediately. Could the motor and ESC be putting put RF noise and blocking the receiver? I have ask for it to be inspected or replaced and am awaiting a reply. The ESc is Turnigy Trust 55amp. Do I need some sort of filtering on the power lead from the ESC? Thanks in advance of any suggestions. All the best from sunny Wales. Yes! the sun is out.............................lol
