I really don’t want to get into a flame war over this but facts are facts.
First off, several other manufactures have “dumbed down” there equipment and it has done nothing but create a gaggle of empty headed thrill seekers who get their jollies from buzzing airports and wild fires.
Second, from a business perspective and excluding toys, designing something that anyone with a pulse can fly is just plain stupid.
Third, commercial aircraft are complex machines and the learning curve to get one airborne is steep for a reason.
Fourth, designers and engineers never listen to end users until the support calls and item recalls begin to happen.
From what I have gathered from this particular thread, there is a flaw in the design of your radio transmitter in that stick movement vs control signal direction cannot be changed by the end user. This design flaw has a direct and possibly catastrophic impact on aircraft and pilot safety. This flaw also has an impact on the safety of public property, private property, as well as the safety of the general population at large. The fact that you are unwilling or maybe even unable to correct this obvious flaw is telling indeed.
As for a providing a link to a solution that I have brought to market, I don’t need to provide one because there are literally millions of RC transmitters on the planet that do not suffer from this same design flaw that was the result of real world disconnect and short sightedness that you have eloquently displayed today.
There fore my initial recommendation still stands. Using a Taranis or any other RC transmitter that is on the market today will allow the original poster to resolve this control issue.
