They should not close until the gear is home and the pressure build up fires the next shuttle.

There are a set of needle valves on the UP3. One set for the doors and one set for the gear. They are usually set from the factory.
You slow them down by adjusting the appropriate needle. You will also need to adjust the gear as well. Small adjustments. Be patient you will get it. If you're doors are slamming shut sounds like the gear is too slow. Another cause could be the secondary shuttle valve. If it is sticking or someone had it apart and did not install the spring correctly it will do that same thing. You should be able to Google UP3 manual and it will show you what needle takes care of what. The other thing that can cause it is if one of your gear has a pinched air line.
