Kyosho Blizzard Dual-540 2-gear Gearbox

New and very compact design

1 set of all the parts works for left or right side. Genious right.

Im not making instructions for this one, but maybe the old instructions can help. You can find them in this project: https://www.thingiverse.com/thing:5848374

All the long spacers are the same. I just made 4 files to make it easy to move them into the slicer.

AxleSpacer1 goes behind the 30t pinion to make sure it is a bit of space behind the gear and the gearbox housing, and ye. Its very tight. This might set your patience on a small test. You can disassemble the frames when assembling this to make it easier.

The gears I'm using are hardened steel MOD1 5mm 30t and 11t, so don't think they will ever strip.

Gears needed for one side:

1pcs 11t

1pcs 30t

Screws needed for one side:

• For the housing

8pcs CS M3x10-12mm (very important these are countersunk)

• For the AxleOutput

2pcs CS M3x16mm (important these are countersunk)

• For the motor

2pcs SH/FH M3x12mm

Bearings needed for one side

1pcs 5x10x4

2pcs 5x11x4

If you’re using 3.175mm motor axle you need a 3.175mm to 5mm adapter https://www.aliexpress.com/item/1005003745412191.html?spm=a2g0o.order_list.order_list_main.34.7e4b1802uMONL1

Theres one spot that need supports, the countersunk screw positions dont need support.
