A little more information. Using the sequence above - when first set up, everything works as it should. If I turn the PB off but leave the Tx on everything works as it should when I turn the PB back on. However, if I turn both the PB and Tx off then, when I turn both on again, the gear immediately goes UP and the doors remain open. If I then blip the switch to up and quickly back to down, the gear comes down and the doors remain open. From this point the gear works normally.
Hope this helps
