Hi

I know that this is not really a solution but this is what we do with our 5U installs.

1. After flying we dissconnect both tanks to drain all pressure as called for by the directions to help the life of the digital pressure sensors.
[Next time we fly]
2. Assemble plane at field.
3. Fill air and use manual button to put gear down. TX off doors will cycle with manual button.
4. Prep fuel air and fly.
