Yeah ... pretty much most of what you write is based on historical circumstances & that thinking regarding FPV quads have remained like that until today ... & that is what gonna sell that DJI honkerGPS positioning, RTH, low battery RTH, OA sensors, probably comes tuned already, more reliable integrated system.
...but my current reservation about using an FPV drone... is if I lose signal the thing is just gonna fly right into the ground or worse so having the peace of mind that if you lose signal it’s not going to crash is a bug plus.
Starting in the order you've stacked up your believed pros with the coming DJI FPV ...
- GPS ... nowadays you can have GPS even on a FPV quad ... I have it & it works, shows me #locked satellites, distance to recorded HP, GPS speed, GPS position & an arrow that always point to HP.
- RTH ... Yep you have it, not as refined as the camera drones, but it will failsafe either with lost control signal or by a switch on the radio (similar to the RTH button) ... it will level out horizontally & either rise to preset height, go to highest height+15m during the earlier flight or keep present height. Then turn to HP & fly home. 200m before HP it will start to descend & will continue until it crash into the ground (the meaning here is that you will regain the control & land manually). No low battery RTH though ...
You have a example of lost control signal RTH here at the set time in the clip ...
- OA sensors ..? On a FPV craft that goes over 100km/h & intended to go low & close for those immersive cinematic shots ... meaningless, I mean it defies the purpose
- Tuning ... Not necessary anymore & you don't need to solder anything either Just buy a so called"Bind & Fly" Quad, they are finalized & pre-tuned for nearly all bigger quad brands ... you don't need to tinker with anything, push a bind button on the quad & pair to the goggles ... push the same button & pair with the radio ... DONE, charge the batteries & fly IF ... you then want to alter any flight behavior you can, can't see anything bad with that.
And as I've already mentioned earlier in this thread ... you have several flight modes.
ACRO: The quad follows your sticks exactly ... move the aileron stick slightly left (right stick to the left) & the quad start to roll to the left & continues to do that until you re-center the stick, & the quad will stay upside down if you center the stick when it's up-side down. Flying in acro means that you can't let go of the sticks & catch you breath ... you need to constantly be on them telling the craft what to do ... fun but exhausting.
ANGLE: The quad only tilts to a preset angle & can't flip or roll ... releasing the sticks to center & the quad self levels horizontally (like a camera drone).
HORIZON: As Angle ... but no tilt restriction, flips & rolls is possible but they will be semi automatic in the sense that the craft continue to roll/pitch if stick is held but no precision is needed to end it horizontally again, that will the flight controller take care of.
In the 2 later flight modes you can catch your breath much more as the craft self levels when sticks is released ... only the height you need to monitor by means of the throttle.
