Good comments so far by several responders. My personal additions:

1. A 50A circuit breaker specified in the plans will in no way protect your
hydraulic pump from burning up should the rotor lock up, neither will it
protect your #10 pump wiring from burning up in the event of a fault. This
error by the factory dates back to the very first kit in 1986(?), and AFAIK,
Lancair has never corrected it. The Oildyne pump draws maybe ~15 Amps when
the gear are in motion, which spikes up to ~30 Amps just before the pressure
switch stops the pump. A 50 Amp circuit breaker will take roughly 3 minutes
to trip with 100 Amps flowing through it. Think about that.

If you insist on using a circuit breaker, 30A would be better, but still
won't protect you from smoke in the cockpit should your pump lock up. (A 30A
or 40A Maxi-Fuse offers better protection.)

2. Yes, connect the control power circuit breaker downstream of the main
circuit breaker for the hydraulic pump. That way, the relays can't stay
energized when the main CB (or fuse) is open.

3.  I recommend high-reliability 75A Bosch Relays for the hydraulic pump,
not the crap that the factory provided. (see details and part numbers posted
here sometime during the last year).

4. Yes, use the back-to-back diodes to feed your "gear transition light".
(See the schematic I posted here a few months ago). I used a red/green LED
which shows red when the hydraulic pump is running in either direction, and
green when the nose gear door is closed.

5. Lance was a true genius when it came to aerodynamics, aesthetics, and
business, but he didn't know diddly about electricity.
