FOLDING PROPELLERS
8 x 4.5 Plastic Folder Reasonably priced folding propeller (200mm x 110mm) suitable for 3.2mm motor shafts by taper pinch aluminium shaft, washer, nut and centre fixing steel screw. All inside the white 39mm diameter spinner, 34mm long. Separate folding blades hinge on machined steel pins. 34mm spinner length. Total 28g
8 x 4.5 Carbon Blade Folder Same as above but with stiffer carbon blades so 29g weight.
7 x 4 Plastic Folder The JP sourced folder with white 39mm spinner. Usual taper pinch fixing and for 3.2mm shafts. A tad big for a 400 motor but the 480 is a better match. Too small for a Mugi Evo but ideal for small tractor propulsion designs. 33mm long and 24g
7 x 4 Carbon Folder Again a JR type but with carbon blades fixed with long crosspoint screws. 31mm long and 24g
6 x 3 Carbon Folder The popular JR supplied smaller prop but for a 2.3mm motor shaft diameter. Carbon blades secured with steel screws. Balances well for high rpm needed at this size; shaft fixing by grub screw and 30mm white spinner . Works with an Evo but CG shifts rearward when stopped; blades self-fold on steel pins. 26mm long and only 9g
