HPD Evo 4 Competition

This is the car I will use for the 2024 outdoor season. It might also be used as a parking lot basher but that is up to you.

An assembly guide is supplied as PDF.

Building instructions can also be found here: https://github.com/Hoglet/HPD_F1/wiki/Building-EVO-4-Competition.

The model is supplied with a rigid rear axle (spool) that is not intended for racing. For competition I recommend to either make https://www.printables.com/model/245261-hpd-evo-2-3-ball-differential or to buy a commercial axle. 

Change log

2024-05-27: Updated

• Front chassis: Bearing seat was too tight.
• Main chassis: More space for servo arm movement.

2024-06-20: Updated

• Rear suspension mount to get easier access to the motor lock grub screw
• Tighter tolerances on the 8mm ride height adjusters to reduce play.

2024-06-22 Added the assembly guide (still work in progress).
