Pitot and Trim

The new pitot tube stalk was completed.  The base that Ed had welded on needed to be cut down to the correct size.  Four edge nutplates were installed on the base.  Then the length of the part needed to be cut down.  All surfaces were then deburred and the four holes needed to mount the Garmin Pitot tube were drilled.

The biggest benefit was that we cut the weight of the part by 1/2.  The original mount weighed in at 5.7 oz and the new part weighed in  at 2.1 oz.  

2.1oz (new) vs. 5.7 oz (old)

Pitot Tube complete
Started working on the trim servo mount and found that the mounting plate needed to be raised up about 0.09" to be flush with the fabric surface.  Two spacers were made from 0.09" aluminum stock.   Everything is cleco'd in place awaiting riveting.  CCC-44 rivets will need to be ordered.  Hours: 2.5
