Aerosani, Snowplane, snow mobile, propellerschlitten, motorschlitten

A word of warning: I made this thing mostly out of parts and spares i already had, you will absolutely have to adjust the design to fit your stuff.

It has ran in snow, with the new skis that are a bit longer and have a taller tip, it runs fine in soft snow. On hard snow it runs very, only problem is that it wants to oversteer a lot. The new ski is also a lot stronger near the hinge which was a weak point.

Use your judgement when printing, the main body parts need supports. Organic supports worked well for me.
I'll upload the fusion360 archive as soon as it finishes exporting

Fits under the body of the Carson beetle warrior and probably other 1:10 bodies. Probably fits most shocks from 1:10 cars, i just had a pack of Tamya TT-02 shocks lying floating about in the workshop.

Print the A-arm and B-arm (yes i know that's not what it's called) 4 times each, the steering components turnylower and turnyupper twice. Careful, you need a normal and a mirrored version of the upper part!

Before you embark on this project, check of you have enough random plastic screws around.

The suspension is held together by 3mm iron rods, but you can also just drill the holes to 4mm if you run out provided you put in enough wall thickness. To attach the upper arm of the suspension, you'll need to buy or improvise some sort of screw with a 12mm long smooth section before the threads start, mine is M4 but other solutions may work. (LONG in the picture) Same thing for the other side of the upper arm, but there the smooth section is only 5mm long (SHORT in the picture).
My short screws are improvised, i took a small wood screw and a section of 4mm o.d. brass tube, it works.
Since all holes are deliberately undersized, you will need to drill out to match whatever screws you could scrounge up.

For the screws that attach the two body halves, use whatever you have on hand. Same for the motor mount and the servo mounting.

You most likely will have to modify the motor mount anyway since it's currently made with a 3-hole pattern for a shitty old pancake motor.

Steering servo: Any standard sized servo should do. Use your judgement.

Motor and prop: Whatever you have. Mine is some no-name 850kv motor that swings a 14x4.5 prop on 4s. Not great (the prop is on the large side in terms of ground-clearance) but it's what i had.

Steering hardware: 4 small heim joints and 2mm threaded rod.
Also required: 4 bearings with 10mm i.d. 15mm o.d, 4mm width. Change the design to fit what you have, they're way oversized and not that critical.

Printing tips:
Print the a-arm with the shock attachment points pointing up. The thin whisker extension on the bottom is to help it stay upright while printing, remove afterwards.
Print all suspension components with plenty of wall thickness so you have enough leeway to drill out any holes. The same holds for the points where the suspension attaches to the body.
Print the main body parts with organic supports.
