NOT trying to get into a flame war here, but just trying to understand why a 6 axis gyro and a receiver with the sufficient number of channels would not work as a VTOL. I DO have a flight controller on the bench and have installed INAV but after watching a number of very detailed INAV videos, the gyro seems MUCH easier. Granted, no return to home, no routing, but with enough power, vertical takeoff should be feasible and landing also, albeit, a little more difficult due to reverse transition. I fully admit such a gyro-based VTOL would be primitive but would it work?
No disrespect to those who've done flight controllers and as I said, I have one on the shelf in the event I can't make the gyro work but I guess I'm stubborn and willing to crash a few to see if I can make it work.
Off my soap box.
