Shuttle Sceadu 30/50 FZ-III Rotor Head System 6mm solid axle with internal threads for securing the blade grips. Floating axle design with wide dampners for extra support of the Feathering spindle. Thrust bearings are standard for smooth collective changes through the entire pitch range especially under the demanding loads of radical 3D flight. New heavier duty blade grips with a 4mm blade bolt are standard for the ultimate in reliability. Accepts 12mm root Main blades with 4mm bolt hole Head button for "palming" the rotor head is standard. The FZ-III Seesaw features adjustable Bell/Hiller ratios for all flight styles similar to ratios successfully used on the Freya. Stabilizer Blades feature adjustable weights and are secured to the flybar with dual set screws. Same paddles included on the GPH346 and Shuttle RG New stabilizer control arm strengthened for those unexpected "oops" Over 22 degrees usable collective pitch available Main Blades For .30 Size Sceadu, 550mm new design factory assembled wood blades are included as standard equipment. For .50 Size Sceadu, 570 FRP (fiberglass) main blades are included as standard equipment. Main Frame All new Main frame design with integrated, easy to access bearing blocks, integrated cooling shroud, .30 to.50 size engine mounting locations, easy glow plug access, provisions for routing tail servo wires from the back to the heli to the servo tray, and even a handy carburetor fuel "pinch off". New heavy duty, front electronics tray with encapsulated foam lined battery box!! No More Batteries coming loose in pirouettes!!!!!! New Integrated easily accessible switch mount capable of handling all switch sizes. Main Frame is capable of handling standard collective pitch controls or Hirobo's SWM(swash mode) 120 deg. CCPM system. New larger Bearing are used to support the clooective lever system for complete "slop" free smooth control for any flight envelope. A 10mm hollow main shaft is included to handle the stresses of rotor head loads on the main frame. Super strong, super light. Drive Train New triple bearing supported clutch/clutch bell system to handle .30 to .50 class engines. New Fan/Flywheel assembly (starter pulley) for improved centering on engine crankshaft. Fan is factory drilled to accept magnet for a throttle governor. New drive train layout puts engine in front of main shaft for better overall CG balancing and allowing the gear reduction for the tail gearbox to happen at the main gear instead of a pulley arrangement. Accepts a DTDS (Direct Tail Drive System) option conversion set for tail drive authority under all conditions! Great for aerobatic autos. A belt driven tail utilizing a lower friction belt is standard equipment. an optional Torque tube pipe drive will be available separately as well. New larger pulleys allow stronger belt contact under the severest of conditions. All rotating shafts are dual ball bearing supported for smoothness. Tail Rotor System Uses the successful Freya Double pin type tail pitch slider for precise tail control. Slider is dual ball bearing supported with "a" links to a ball joint on the tail blade holder. Each Tail Blade Holder uses a single thrust bearing and radial bearing for exact rotational movement. New aggressive super stiff tail blades are included as standard equipment for the 9 3/4 inch tail rotor disk. Super tail power for today's demanding gyros. Tail Boom Mounted Servo for tail control is standard equipment Also available will be a 5mm control rod to replace the 2 mm existing rod. Muffler New higher capacity sealed muffler also included. New Cabin design and materials New shaped cabin is sleek and fast like the Shuttle's Big Brother's, the Eagles. Made of durable impact resistant polypropylene. Blow molded for smooth round Lines and definitely shock resistant. Tali fins New larger shaped fins effective in fast forward flight when decals are applied or ideal for 3D flying with their decals removed. Fuel tank New rear mount location with 4 point suspension in the main frame. New centralized stopper allows dependable clunk line freedom. Now 370 cc, increased 120 cc from the previous Shuttle Tank of 250 cc. Very transparent for easy fuel level checks.
