My Ridge Runner comes in at 16.5 lbs. with a Saito 180.
Just finished the full cockpit with a "Doc Miller" pilot from Blue Box Toys. Made a plywood seat with armored back and head rest, raido detail on the rear shelf, cockpit sides from a Top Flite kit and home made instrument panel.
The rest of the weight comes from the drop tanks, retract tail wheel and a extra elevator servo for a total of 14 servos.
Will do the first (of many) flight next weekend.

Sorry, I stoped reading the thread title after "World Models 80"" and thought the topic was the Mustang... never mind.
