Clearly you don't know about the Gpro flybarless system he has on this machine then
First you say 3GX then you say GPro?
Those are two different systems.
Video is from february 2014.
No GPro back then.
You quote:
Not to mention;
● Additional peripherals
planned for the 3GX includes 3-axis accelerometer, etc...
The additional functions can be added by the APS gyro. This system was not mounted, as there is no GPS sensor on the horizontal tail fin.
And there is no such thing as a crash avoidance system (CAS/CAT, whatever you wish to call it). Not yet at least.
Sorry to say this, but clearly you don't know what you are talking about...
