Charley, 

If you are just changing parts to see if it fixes the problem, then try the
$85 version.  It is an experimental plane.  :<)

Subject: [LML] Airspeed switch

Gang,

On my Legacy I have an airspeed safety switch, the standard Lancair part no.
710 from Value Engineered Products.  Mine has a strange problem:  It tests
perfectly on the ground (bench or on the airplane in a gear swing), but in
flight it remains open and prevents retraction -- most of the time.
Immediately after takeoff, gear retraction's not a problem but on a
go-around, or (dare I say this) after practicing stalls up and away, it
generally prevents gear retraction.  

I know this is not a hydraulic problem because when I rig an electrical
jumper around the switch, the problem goes away completely.

So I'm thinking of trying a new replacement switch ($385 through Lancair),
but thought I'd ask:
-- Anyone had a similar issue?
-- Anyone using the much cheaper ($85) Universal switch from Aircraft
Spruce?
