CHOOSING A SPINNER
(1) Check your model to see what DIAMETER spinner you need.
Examples: 30mm, 38mm, 40mm, 45mm spinner diameter
——————————————
(2) Spinners have 2 dimensions you must choose to fit your propeller:
S : The width of the propeller where it fits the spinner hub
R : The diameter of the mounting hole in the propeller
Our folding blade sets have “S” and “R” listed in the description, like:
Graupner CAM Folding Prop 8×4.5 (S-6, R-2) 2 BLADES ONLY
Decide what Prop you want to use, and write down the figures for S and R
——————————————
(3) Now, choose the correct Collet Size to fit your Motor/Gearbox
C : The diameter of your motor/gearbox output shaft
Consult the makers specifications for your motor/gearbox to see the shaft diameter
——————————————
Example: Your glider nose fits a 40mm Spinner. You have a Hyperion Z3007-26 motor, with 4mm output shaft (C=4). You want to use 9×6 Graupner CAM folding blades (S=8, R=3)
Use: MPJ-4741W Spinner Set
