I have the Xicoy in both my Der Jet F-35A and JL F-22 and it works perfectly! I had no qualms about using it at all...once I understood that the delays are post action in the 3 central steps. The servo end points are exactly normal as they should be. Is it possible you have one that might be faulty?

Mine sequences perfect...my issue starts when the plane is turned on...after the plane is put together it always sits on the ground with gear out. I have used all 3 start up options of the sequencer and every time it turn on the jet ( Shockwave ) the nose door wants to close, thus popping the nose door servo former off. So now I unplug the nose door servo after every flight and then 10 seconds after I turn it back on I plug the servo lead back in.
Is it normal for this to happen. I really like the ALL IN ONE fail safe and sequencer. Easy to use and setup, once you update your brains firmware..LOL
