Hello everyone. I have a heli cpd20s serial number 060201D6280. Configuration s-cq2. It has an alarm 30 on node 3. We have just received the controller back from the dealer after being rebuilt after the cooling fan failed and the unit over heated. The code comes up as soon as you you turn the key on and the truck has zero control functions. Has anybody come across this code or have any troubleshooting advice.? Thanks in advance. loewen12 at hotmail dot com.
