Hi Gaspar

When power-up, all gear and doors should be in open position, either is the switch is in open or closed position during power up. I once crashed a door in my Hawk because of this. Now I will do the inicial cycle with low pressure.

Great, we will read pressure in the TX. I like air operated systems. Just build them properly and they will be reliable for years. For some scale jets there is no alternative either and it is very hard to find pressure fail safe these days...
