This version of the Traggi is designed for those who want a more complex and reliable design. I recommend assembling it after assembling the original version https://www.thingiverse.com/thing:42198

OpenRC Truggy by NiKO includes many improvements to increase reliability and durability. Among them:

Increased space for >3S 5000mAh and more batteries
Battery fasteners with Velcro
The central differential uses a combination of metal and plastic parts mod 1.
The front and rear differential housings are made of HSP metal.
The C-HUB has a more convenient snap-on design
The fists are made for cheap steel CVD HSP drives with large and small bearings
The original shape of the levers
The steering unit has been updated
Increased suspension travel
Ackerman angles are calculated
and a lot of little things.
