Small test bench for adjusting servo travel directions and simple motor setup.
This small bench was inspired by "RC video review": https://www.youtube.com/watch?v=1S74TF4YutQ&t=1086s

I started from scratch to make it more general-purpose, practical, and just as easy to print.

All moving parts clip together.
Cable management is facilitated by reusable clips.
Everything prints without supports.
A 'standard' layer thickness of 0.2 mm is sufficient.
The printing parameters are standard.
Optionally ensure that the infill is at least 25 or 30%.
It is advised to print the parts that clip together in PETG to take advantage of flexibility.
The cradles are designed for micro servos. The tolerances are generous.
The motor cradle is intended for motors of about 30 mm.
The engine cradle is reversible for engines with front or rear mountings.
The rear stabilizer can be T or V-shaped.
A very good flight controller is required to make it fly (joke).

If there's too much friction for the moving parts, a very small drop of lubricant immediately solves the problem.

There are markers (circle, triangle, line) on the control surfaces and on the control horns. These markers allow for the correct selection of control horns for the different control surfaces.
