Here another set of 14 tooth bevel gears drives the 4 blade tail rotor. Because of the shape of the gear, the rotor can pivot on two axes while still rotating. The nose gear retracts forward via a set of 14 tooth bevel gears. The flex cable runs up to a link lwgo lifts the swashplate using a suspension control arm! Click for an animation of the landing gear in motion. The next axle pivots a lift arm which deploys the winch boom.

Click for an animation of the cyclic in motion. If a real helicopter did this it would risk striking the rotor against the frame. Click for an animation of the rotors in motion.

In both the extended and retracted positions the gear rests against a hard stop. Click the image to download the LDraw file of this model. Ldraw file courtesy of Benjamin Wendl. This crank drives a set of 14 tooth bevel gears giving the main rotor a ratio of 1: There is one flex cable and sleeve for each axis. The final gear ratio is This model pivots the entire rotor head instead. Rotors The rotors’ rotation is driven by an input crank on the left side.

The crank turns a worm gear which mates with a 24 tooth spur gear. Each gear pivots a little over 90 degrees.

Fore-aft motion of the stick pushes and pulls the cable using a ball joint. Click for an animation of the winch boom deploying. Inside the swashplate is a four blade rotor part.

The ball joints also keep the swashplate from rotating. Landing Gear The 3 point landing gear retracts using another crank on the port side. The main gear pivots forward via a 24 tooth crown and spur gear.

The spur gear drives an axle which runs both forward and aft. The control of the cyclic is from a stick at the pilot’s position.

Model by Eric Albrecht. Real helicopter cyclic works by changing the pitch of individual blades as they rotate using a swashplate. A set of 14 tooth bevel gears drive the second axle which works as a cable drum. The cable runs out to legk winch and attaches to a metal hook.

The first crank turns a worm gear which drives a 16 tooth spur gear. A pair of simulated turbine engines are nestled beneath the main rotor head. The second crank attaches to a 16 tooth spur gear used as a ratchet plate.

886 example, the leading and trailing blades may be at 10 degrees of pitch, while the port and starboard blades are at 5 and 15 degrees respectively.

Click for an animation of the cable in motion. At the end of the axle is a ball joint which connects to another flex cable. Cyclic Pitch A number of new parts made a simulated cyclic system possible.

Rotating main and tail rotor, ratcheting winch on deployable boom, retractable landing gear, working two axis cyclic. Rescue Winch A pair of cranks on the starboard side operate the rescue winch on the port legp. Lateral motion of the stick rotates an axle which runs aft. The rotor axle drives a spherical ball gear.

This flex cable attaches to a ball joint on 886 side of the swashplate. The crank axle also drives a set or gears made up of a 24 tooth crown mating with two stacked 14 tooth bevel gears one of the rare places this pairing is made which passes torque along the length of the boom to the tail through 3 universal joints.
