Totally agree about fundamentals. However, learning the basics of a flawed system by design is another cup of tea. A few decades ago, someone sat down and wanted to make a remote control plane/copter/eventually quad. They developed several independent systems to handle individual functions and lumped them all together in a remote, then tried to pair it down to as few control actions as possible.
It is a system developed by engineers...for engineers.
Fast forward a few decades, the focus has been on making marketable products with off the shelf technology. Hence the flawed control system. This was reinforced by testers who grew up with the flawed system themselves making recommendations on improvements. Hence, focus on programming updates but no deviation from a control system they grew up with.
Do you know why they do not make cars that have a throttle attached to the steering wheel? Or an airplane with the throttle on the same foot pedal as the rudder? Sure, you can make it work with enough practice. Might even live through it too. That is not basics, it is poor design. It is also the largest obstacle new fliers have issues getting past. Why most fliers never make it past a few battery cycles in the family living room before it goes in the trash.
Developers need to stop asking the pros and start asking the newbies what they do or do not like about the product. How to make it better and more entertaining. That is where the potential market growth is. The concept of flying is a dream shared by many. FPV opened the door to the dreams of millions. However, they want to play. They are not interested in another job. Games and toys that have a large learning curve do not get a lot of attention. There is always that niche market, but it is infinitesimally small to the general potential market.
The i-phone and android beat the tar out of windows because it was intuitive. simple to understand and use. It is way past due for an I-phone revolution for quads and the time is right.
Redesign the control system to something more intuitive, simple and easy to understand and use. Get the rudder off the throttle stick. That would be a good start, in my opinion. Tying it into the pitch stick would be even better. Headless tech is fine for the kiddies but it stops the moment you strap on goggles which is where most of us want to be. We want to fly. And why is Headless so popular with the kiddies? Because you do not have to deal with the rudder while you are busy dealing with altitude and speed and you only need ONE control to turn, not two...while you are dealing with the throttle to control altitude and speed at the same time. It is a bad design. Cudos to the peeps that did the bleeding to make it work. The rest of us want to play, not bleed.
