Rob Wolf, In regards to your question about flap motor current for the LNC2,
I measured the current draw on my 320 kit purchased in 1989.  The initial
surge at start-up is about 4 amperes.  The normal running current on the
ground is less than 1 ampere.  In flight, lowering the flaps with wind
resistance, the current will be more than this.  I have not measured the
current in-flight.  In any case, the current will never be more than about 4
amperes because the internal resistance of the motor is about 3 ohms.
(12/3=4).  I used a 5 amp circuit breaker as shown in the construction
manual and have never had it trip.
