2020 Bronco?
Tried to make as much printable as I could.
You could put the body on something else or put a different body on the chassis.
Probability a few parts missing. If a part is missing or wrong ask, I'll have it somewhere.
Wheel base 260mm
Width 190mm
Diffs
Axle with ball diff
Uses the Ursa Bear hubs
Locked hubs to use it as a back axle, will make straight axle end to go with it soon.
Ball diff the same as my other one, just different https://www.thingiverse.com/thing:2826921
Started making a hub, but found the hub from the Ursa Bear fits. Maybe I'll finish mine one day. Some of the other parts have evolved from from it.
4x12x18 Bearings x4
Thrust bearing https://www.banggood.com/XLPOWER-520-RC-Helicopter-Parts-Tail-Thrust-Bearing-Set-p-1229065.html?rmmds=mywishlist&cur_warehouse=CN
3mmx20mm cap head bolt
2mmx? need to measure x6
.177 cal BB's 4.5mm for the balls in the diff
2x washers 21.68mm x 1.14mm (don't need to be exactly the same)
Transfer box
Parts needed
3x3x7 bearing x1
4x12x18 bearing x3
RC Gearbox V3
Bits needed
3x12 shaft x1
3x26 shaft x1
3x3x7 bearing x3
4x12x18 bearing x1
540 motor
3x20 cap screw x2
28/6/18
Test of the chassis https://youtu.be/8dj2QouBvAQ
Added non steering rear hubs, axles and stub axles.
Front axle needs 3mm cut off on the thrust bearing side.
New diff housings with more clearance in case of thick washers in the ball diff.
2/07/18
Added floor pan, door hinges, 118mm steering link to fix toe out, longer suspension links for the front 104mm (could use them in back as well) and the dash.
Floor needs 4 holes drilled, uses same bolts as the transfer box. It also hits the gearbox but I just trimmed mine to fit.
Its a bit slow with a 55 turn motor, might try it with a straight drive from motor to gearbox soon.
Update tried 80 turn and it barely moved.
7/11/18
New dash with direct servo to the wheel, simpler and more compact.
18/9/18
V5 diff housing with stronger top link mount.
V5.1 diff housing slightly more ground clearance and holes reversed with heads at the bottom so it can be disassembled with out removing from chassis
My new planetary gear box fits this and is simpler and smaller.https://www.thingiverse.com/thing:3081347

New steering link 118mm v2. Fixes all the weird steering stuff that was going on.
18/12/18
Added missing cab back like in the pics and the original covered rear parts. (Probably missing due to the poor internet here)
01/01/19
Proper length axles added.
back_axles_40-45mm.stl
front_axles_31-38mm.stl
02/01/19
Back stub axle 2mm shorter for clearance.
09/06/20
Added missing tail and head lights
and mirrors
