Default RE: Aurora 9 and servo jitter


ORIGINAL: Brent@Amazian Hi
I was wondering if anyone could help, I have just purchased an Aurora 9 with exactly the same jitter probelms on the servos. If I turn on the receiver after about 30 secs the servos go nuts. I have also tried different receivers with the same problems. The batteries are fully charged and certanly capable of driving the servos. If I connect the SPC port direct to the Lipo I intailly get a voltage reading of around 22 Volts whichI confirmed with a multimeter, after about 30 secs the voltage on the Aurora 9 display drops to approx 18V which is incorrect as the multimeter still display 22v. I am now convinced the transmitter is faulty and was wondering if it would be worth whileordering another TX Module before sending the handset in for warranty I am in a remote part of South Africaat a lodgewww.amazian.netand maybe should have gone the Futaba route. Has anyone confirmed where the jitter problems are originating? Thanks Brent
