Description
Anti-shock Landing Gear with amortization based on the cheapest wheels available on the market (linked below)
I've made it with two parts: mount and landing gear.
This is because it will be easier to replace after a crash or break.
No support and no glue are required! But You need springs. Can be standard pencil springs (1 or 2 per wheel, depending on plane weight)
The optimal outer diameter is 4mm and should be longer than 30mm.
Fit for most models around 80-140cm, just choose the angle that You like
Wingspan on my model is 100cm
Safe plane weight is lower than 750g. I tried to use those wheels also with a 900~1000g model, but only printed parts survived dynamic landing on a meadow ;)
Printing tips
The locking rod is extra small and designed for 0.2mm nozzle to keep maximum durability
But no worry if You have 0.4mm nozzle, it's ok. Just print only the rod. Should not slip out. Optionally, You can slightly increase X and Y diameter (like ~5%)
Edit history
May 2025
• fix for 10 and 15-degree v2 models
• added 0 and 5-degree v2 models
Apr 2025
New element added: locking rod
You can use 2mm screw but nut may be to big, so I added rod model in two version:
• rod_a, which requires a single cap on the one end
• rod_simple, which requires two caps on both ends
earlier
I also made a 3rd version of this model with a different mount part, and I also attached it here
My first model with no amortization is here:
