Matt, concerning your gear retract problem, try cracking open one of the
high pressure (up circuit) hydraulic lines to relieve any built up pressure.  I've done this at the sequence valve.  Retighten the fitting, then fly and try it.  You'll see in the archives that I had a similar problem.  The root cause was an internal leak somewhere allowing pressure from the down side to leak to the up side.  This combined with heating from a warm day caused the pressure to climb in the up circuit (while on the ground) to the switch trip point causing the system to think the gear was already retracted.  Another possible cause is the gear minder system if you installed this from Lancair.  Mine seems to have a problem where occasionally it refuses to allow the gear to come up.  It also sends spurious gear warnings.  I bypassed it.  I've not had any gear retraction problems since. Regards,
Ed de Chazal
