[RC Model] Mini Remote Control Rotorcraft 3.0 Trial Version (Standard + Pre-rotation Component)

This project was originally the first work in this year's open-source series The first physical flight test was completed by the end of May, but various problems always prevented it from flying smoothly After much deliberation, the transparent paper airplane in June and subsequent works were created It has now been improved to version 4.0, but the problems have still not been completely solved The 4.0 design is complete but already exceeds the 250-gram safety specification Next year's new drone regulations will impose comprehensive restrictions, and time is running out for me

So I decided to change my approach and directly open-source the mini version of 3.0 Back then, I didn't add auxiliary flight control, and pure manual remote control led to crashes upon takeoff, which was a major mistake on my part As the most likely to fly and lightweight version, I hope to leverage the power of all players to further test and optimize this design, and consider the full 5.0 design based on your feedback (Of course, if you all can master version 3.0, then there will be no further need Time is short, and I need to further explore other designs)

Looking forward to your feedback! Thanks!
