set the ventral fin solidly on the saw horse. Takes about 1= 50 # in my case.

At this point the nose gear is now= off the floor. Then continue jacking until there is sufficient cleara= nce to cycle the gear.

If you want to leave the pla= ne jacked up for extended periods, place lengths of 2x4's in the jacks to pr= event them from collapsing.

Reverse the process to g= et the plane back down on the floor.
