Rob,

Once you have your plane right side up, which would be up side down here, do a gear free fall test with the springs removed.
You want to see how close the over center mechanism comes to locking. They probably won't. Measure the force required to
lock the gear, it won't be much. Use of rudder to yaw the tail left and right at 85knots will most likely produce enough force on
the gear doors to lock the gear down.
