Xicoy failsafe/sequencer
A simple question for anyone using it, I am putting these in all three of my models at the moment. I am pretty sure I understand the instruction but on one model I need one set of doors to open then the other to prevent binding. The instruction refer "steps" is one of the steps a delay between the two doors or just the delay after gear up and before gear down? If that makes sense, thanks up front
and for anyone wondering the telemetry works great. Im using the 18mz and it uses a temp slot so you will see 100 PSI as 100C and then just set alarms in the radio to like 80c which is 80PSI
Nice to finally get some telemetry working, only luck I have had so far is receiver voltage but even thats worthless since the voltage to my receiver is from a power system. and being able to use my turbine gsu control box to do the programming is nice!

Below you have a drawing of the sequence.
Basically, the retraction/extension process is divided in 5 different steps that are executed sequentially. On each of these steps you can define the position of all the 5 outputs. On "Gear Up" you sure want the gear up and doors closed, and in "Gear Down" sure you want the gear extended, but could be that you need some doors open and other closed. If some closed, sure you want these open during extension.
The "time"is the number of seconds that the sequencer wait in each of the steps.
For example, say that you want your sequence like this:
On "GearUp" position all closed.
During extension you want one of the doors open first, wait 2.5 seconds, the open the other doors, wait 1 s, deploy the gear and, wait 3.2 seconds and close the first door.
Say that you have the valve/servo that controls the gear on output 1, the valve/servo that controls first door at output2 and the valve/servo that control the other doors at output 3.
Then set:
On GearUp Step: All closed
On"Step1" Door 2 (D2) open, all other closed. Step1 time: 2.5 seconds
On "Step2"Keep D2 Open, and set D3 Open. Step2 time: 1s
On "Step3"Keep D2 and D3 Open, set Gear (G1) to open. Step3 time 3.2 seconds
On"Gear Down" step, Keep D3 and G1 Open and set D2 to closed.
BTW, if you are using a Futaba radio with telemetry, on a less than 16CH RX, then you can set the gear switch to one of the unused (by your RX) channels and use the SBUS capability of the sequencer to save one of the RX channels, the RX information of all channels is already decoded in the sequencer, necessary for to manage the telemetry. This would enable the 5th output on the sequencer and save one wire from RX to sequencer.

Okay the struggle continues, so can anyone explain how to setup the end points of the retract gear servo? The only option i am seeing is the up/down end points but that just tells you the freq for the switch position for gear up/down.

never mind on the above question, figured that part out and after all day sitting here trying to program this thing and it not working I ended up have my servo for the gear valve go bad. This is the 2nd servo that has done this, I replaced the last with the same servo and it has went bad also. DAng you hitec!!! I plugged in a new servo and it worked, this F-14 is just bad mojo. Cant stop the gear from breaking lock cylinder arms 
anyway sorry to waste your folks time

OK Guys. I have this xicoy sequencer. I have yet to figure out exactly how to make it work.
I have servos connected to the out puts #1 for gear and #2 for the gear doors.
I seem to make it go up correctly then it stutter steps and opens.
Anybody have any tips or real world setups that I can follow.
Thanks Clay

Sorry your having problems, the programming is not the most user friendly for sure. Once it clicked for me it made since. What's helped me was watching the sequencer screen while flipping the switch and looking at the diagram.

For anyone else using this sequencer, I hope this helps
I have one valve running the gear on G1, One valve running the doors on G2
If you look at the chart.
You have gear down and gear up at the top and bottom of the chart.
Gear down is where I started.
G1 open gear down
G2 Open Door open
Step 1
G1 open gear down
G2 Open Door open
Step 2
G1 open gear down
G2 Open Door open
Step 3
G1 open gear up
G2 Open Door open
Gear up
G1 Closed
G2 Closed
That should complete the cycle.
I hope I explained this correctly.
