Classic Fundamentals...a tutorial...Deception nose gear, rudder, elevator, throttle linkages.

Deception nose gear- The Dave Brown nose gear is operated by seperate servo, in this case a Hobbico retract servo. The servo is mounted to R/C City (long gone...) plastic 90 degree servo mounts, on a 1/64 plywood "pad" with medium Zap CA (green label). The wire has been rough bent to shape with a "z" bend made with "z" bend pliers (Great Planes) and my favorite Hayes 2-56 nylon clevis with steel pins.

The steering is a plastic tube with a sullivan cable attached to a shaped wooden block with carbon fiber matt over the rod and block (black stuff). The tube was then heated with a MonoKote heat gun, with the tube installed, while holding a tighter "s" shape. When it cooled the shape mostly remained. The assembly was connected to the steering arm in the "retracted" position, the floaty deal was centered and the block was glued with ZAP medium CA...keeping it straight here is very, very, very important for trouble free operation.

The steering tube will be supported by a shaped balsa block during the final adjustment. Note that the plastic tube runs just above the throttle servo arm and the throttle wire/arm is inverted for clearance.

The elevator/rudder/throttle/RX tray- is made of 1/8" lite-ply with 1/8" x 1/4" spruce cross braces. The location of the servos and tray were determined on the full size plan. The rudder servo is mounted on the 3/8" stand-offs and will attach to the rudder ABOVE the stabilizer. Okay, your asking what about the elevator pushrod? The cables will "cross" above the pushrod and not interfere.

Various pushrods for Calypso, Komet (small 3/16" rods), Dirty Birdy MK elevator bellcrank and Deception.

Steering mechanism thoughts? Good luck!
