Hi Ferg
Just one option is to use an airspeed switch. You can use a stall warner switch
as Europa supplies, it can be adjusted to turn on with vacuum or pressure, or
off with vacuum or pressure.
We are incorporating gear and door warning on our XS Monowheel, details below:
Throttle position switch (reed)
Airspeed switch (Europa stall warner that is readjusted)
Outrigger switches (sealed McMaster)
Airbrake switch (sealed McMaster)
Main gear down latch switch (reed)
Door aft shoot bolt switches (sealed McMaster)
