OpenRC Truggy HSP Remix

Last crawled date: 4 years, 2 months ago

This is a remix of the OpenRC Truggy by Daniel Noree. It uses driveline parts (differentials, motor plate, center gear, dogbones, etc) from HSP RC cars. These parts are inexpensive and available on Amazon and AliExpress. Some of the printed parts are the same as the original Truggy, but most are tweaked to accommodate the HSP components.
In addition to the standard components required by the Truggy, You will need to order these HSP parts:

Edits:
2019.11.17:
Wishbone_v2
Steering_Block_v2
C-Hub_Rear_v2
Changed the bearing pocket sizes in the steering block and rear C-hub based on feedback from jritt187 (thanks!). They were oversized at 10.6mm and 15.6mm. Now they are 10.2mm and 15.2mm. Also added print helper to the wishbone and reoriented it to print like the original Truggy wishbone.

Wishbone_v3
Changed the wishbone print helpers again to use less plastic and detach easier
