Subject: LNC2 Gear Up & Down Problems

I have determined that the problem is caused when the hydraulic  
pressure at both switches is high enough that not only does the pump  
not run but also high enough that when the dump valve is opened the  
pressures are still not relieved to be below the pump run setting. eg.  
If I fly high and the temperature on the ground, after landing, is 60  
degrees farenheight more than the temperature in flight, the gear  
won't go up on the next flight.

An EE friend of mine, after seeing our hydraulic system schematics,  
talking to Lancair and talking to Oildyne, has come up with 3  
solutions to the gear not going up and/or coming down. I am out of  
town and haven't had the chance to see the solutions. Would anyone be  
interested in a kit that solved the problem for $200 to $400.
