Anyone seen this?

Ah ha! I didn't know you were using this sequencer! I thought the sequencer in the radio.

I will talk to juan tomorrow.

Have you switched the lines on the electronic valve.?

I do not try to program the valve, I see which way the fail makes the gear down in the failsafe mode and that is how I install the lines.

If the failsafe unit is supposed to "read" from the radio the direction of gear travel..why should I have to change gear valve lines and all door sequencing ? Have two of them...both operating same way...
Its like the don't understand signal pulse ???

Anyone have this problem?

Bill
hook a servo up in place of the sequencer and check if the servo holds last command when you turn off the tx. Also, check if it goes to the "gear down" position at turn on. This will help me understand if the tx/rx is behaving.

had the same issue with a Jet Tronics gear valve. Nothing fixed the problem on initial startup until I switched air lines for up and down.

If you haven't already tried it, try increasing the travel of the channel in both directions.
