Guy's I am speaking to Danny directly when I find any more news will let you know. As of now I have gone thru my jet completely checked each individual control surface and servos . All servos are fine ,all wiring & connections excellent all servos pulling a normal idle load no binding at all. I will say that all of my equipment that I use is all high end with no short cuts. I have used Cortex Gyros on all of my jets with no problems whatsoever , At this time I do not want to jump to conclusions for this has been an extremely good product but it is the lifeline to your jets Longevity inflight? I noticed the failure when attempting my 9th flight on this jet and had to rebind my AR12120 spectrum receiver 4 times to take the bind? All antennas working? Finally a successful bind but out of daylight so I decided to call it quits for the day Lucky thing? Got to the shop unloaded the Yak 130 connected battery's for I wanted to drop my gear and noticed Cortex Gyro light not powered No stab power , no. Aileron power , no Rudder ? Checked wires no problem pulled cortex out and noticed a strong electrical burn smell! all pins straight no wire were burned but the Cortex unit was dead. This is all I can tell you guys at this time? Could be one bad cortex in the batch? Will keep you informed, it might be worth checking yours out to be safe (Sniff Check)....
