Buddy Box = Someone else to blame and pay for repairs. (They are supposed to save the Helicopter. Right??)
Normal Flying = Crashing right side up
3D Flying = Crashing upside down. The art of flying inverted, many times combined with rolls, loops, flips, etc.. Without using a switch on the transmitter to correct the inverted controls when flying inverted
Out of balance battery-pack is when some of the cells in the pack still had some charge left in them while others have no charge remaining.
Trickle Charge = A trickle charge is less than C/10 and is meant for continuous charging for standby devices such as cordless phones
Autorotation bearing = AKA "Autohub", "Auto gear","Autorotation Wheel" when referring to the whole main gear assembly with AR bearing installed.IKARUS #s 67703, 67705 (Aluminum Hub)
Main gear = Ikarus # 67536.Also called "Spur Gear" being as it's the gear meshing with the motor output gear (pinion gear)
Main shaft = "Main Rotor Shaft" Ikarus #67535; 67940 (Hardened)
Main shaft bearing blocks = "Upper bearing case" Ik# 67521; Ali upgrade available. (Sly's, FX, PMP)
Swash plate = "Upper plate/moving swash plate/"Star" "Bottom swash plate/ stationary plate/"cross"
eCCPM = Also called here just "CCPM","Radio Mixing","Microcomputer Mixing"
Anti rotation slider = "Antirotating pin holder"(Seizbonics)"Swash plate handle" Ik#67629
Washout unit = "Collective Pitch Compensator", "CPC" composed of Center Hub #67590; 2 "arms"#67591; and 2 Y-arms #67635.CPC adjusts overall main blade pitch during collective pitch input, and adjusts flybar pitch with cyclic input
Main rotor = "Rotor head" composed of Rotor Center Unit(Rotor Head Block,"T Tube")#67639; Feathering Shaft/Feathering Spindle/Blade Shaft/Blade Bearing Shaft #67509 (67942 Hardened); O ring Dampeners #67588; and Main Blade Holders #67511. Rotor head connects main blades to main shaft in a way that allows the blades' pitch to be adjusted. The loads of lift and flight inputs are hard fixed to the main shaft with the "Jesus Bolt" (Rotor Head Screw #67599)
Feathering spindle = "Feathering Shaft","Blade Bearing Shaft"
Bell-Hiller mixer = "Mixerlever" #67578. Ajusts pitch to main blades depending on collective/ cyclic pitch inputs and flybar pitch. As flybar pitch changes translated from the upper swash through the pitch compensator, the mixerlever arms translate those movements to the main blades as the entire rotor head rotates, so that the main blades' pitch is gradually increased/ decreased on the corresponding "side" of the copter to produce the proper roll or pitch ( pitch being tilting the nose up and down)
Flybar seesaw = #67610. It attaches at a pivot point to the Rotor Center Unit so that the flybar can pivot up and down; which allows the flybar to act as a gyroscope to stabilize the helicopter in flight. The flybar swivels in response to cyclic input and tilts to an "equilibrium" of cyclic input and its own rotation. This makes the rotor head more stable.
Flybar control arm = "Seesaw Lever" #67608. These are fixed to the flybar and connected via links to the pitch compensator arm ends.They rotate the flybar and adjust flybar paddle pitch, which tilts the flybar down in the direction the helicopter will move.
Dampers = "Rotor head Rubber Dampeners","O rings"# 67588. Without these, the forces acting on the main blades would literally disintegrate the helicopter. The thrust of the blade rotation, along with the up and down loads of the air resistance would shake the helicopter to pieces and cause the "head tube" across the tob to split apart. Real helicopters have a MUCH more complicated dampening system for the same purpose.
Jesus bolt = "Rotor Head Screw" # 67599. This screw fixes the rotor head to the main shaft and carries ALL of the load placed on the flight surfaces. It has been known to bend into an "S" shape during an impact while the blades are spinning at high RPMs. It LOOKS way too scrawny for the job it does.
