I’m currently working on a VTOL aircraft project, and I ran into something I’m not fully sure about.
I got a drone from someone to salvage parts from it, and the motors it came with are designed for self-tightening (screw-on) propellers. So the props just thread directly onto the motor shaft and tighten as they spin.
From what I understand, those props are meant to spin in a specific direction so they stay tight, and spinning them the opposite way could loosen them.
Now here’s where I’m confused:
For my VTOL setup, I’ll likely need a pusher configuration (motor at the back) for forward flight. That might mean reversing motor direction depending on how things are mounted.
So my questions are:
- Can self-tightening props be safely used in a pusher configuration?
- If I reverse the motor direction to get proper thrust, won’t the prop just unscrew itself?
- Is there a correct way to orient/setup these so they still tighten properly?
- Or is it just better to switch to standard props with a shaft + nut for this kind of build?
Would really appreciate any advice, especially from people who’ve tried something similar.
