My inroduction to drone flying was back in 2010 when, Fran my model flying buddy, decided to have a go at making a tricopter. This machine was made of balsa and lightply, had three brushles motors and was controled via three servos, a reciever and three gyros. No controllers for drones in those days.
We spent many hours ,sharing the flying, while trying to iron out many problems.
Eventually we suceeded and went on to build a Quadcopter and Hexacopter.
two videos exist on Youtube via these links.
Fran still flies the quad version but now fitted with Naza V2 controller while I fly a flame wheel quad fitted with Tarot controller and a flame wheel hex fitted with Naza V2 controller.
We both fly model helicopters and Fran has built a large Chinnook twin rotor machine.
I have bought a Mavic air 2 but lockdown has prevented me from flying t other than a couple of test hovers.
