There are two internet forums dedicated to the N3N aircraft:
The N3N Pilot’s Lounge
The N3N Pilot’s lounge (groups.yahoo.nafn3npilotslounge) is a yahoo use group. The group is focused on owners – their requests for help – and as a way to keep everyone informed. The group requires registration, going to the link below will provide registration instructions. If you are an owner just provide Jeff (the group owner) with your aircraft information using the link below. If you’re not an owner then describe your interest in the N3N and he will likely let you join (he let me join before I had any affiliation with “N3N Owners” – ED).
