IN MY OPINON (Which should be in giant cursive like the DOI), with
extremely limited experience with
goggles and a
M2P I think a lot depends on a lot. It should be noted that I've just been playing around with VR
goggles, but other than resolution and other available data via Litchi, the experience shouldn't be that much different. When I fly indoors, It is usually in smaller spaces in a home with a
Mini 2 for practice for slow speed and precision. The
Mini 2 isn't the best drone for that because the stick inputs can be a little unruly combined with latency. The
M2P is better suited for precision with its tripod mode.
Asking if
goggles will help smoothness I think is dependent on a few things but I would have to guess in terms of pure smoothness, not directly, but perhaps indirectly. With the limited time I've spend with my M2 and VR
goggles where they really change my perspective is with spacial awarness. In other words, a better indication that I'll be flying through spaces rather than crashing into objects. I haven't yet got up the nerve to turn the sensors off, which can be a problem in a tight space- but they obviously should be turned off. But will that cause the M2 to go into the "Atti mode" which can be like driving on sheet ice with 40mph gusts pushing you around? I don't know, but I had my M2 go into Atti outdoors a few weeks ago and it was a little scary keeping control and getting it back home safely. On my
Mini 2 I have prop guards which I would definitely get, and will get for my M2 should I need to fly indoors.
When I said "it depends", what I've found when flying my
Mini 2 in hallways (I hope I use the right term) it's "prop wash" gets deflected off the walls or floors or objects and makes it veer off line a bit. I think with the tripod mode the
Mavic 2 would be much easier to control in such circumstances. I was flying indoors today and was filming a good sized bathroom with a fairly large tub/jaccuzi and the prop wash from the tub pushed my
Mini 2 in a manner that required some agile sticksmanship. But entirely smooth it wasn't. Perhaps the M2 would fare better? Without prop guards I haven't dared to fly my M2 indoors yet.
Getting back to the
goggle thing, the question might be, instead of making things smoother, will they help or hinder your operation. If the drone is just moving forward and doesn't need any lateral adjustment I think they can be helpful. If you have to move the drone sideways you might need to visually inspect how it's lining up which would require popping the
goggles up. Not so difficult but inconvenient because you lose the screen view. So while they could be a help on one hand, they could be a hinderance OTOH.
Again I'm only using $20 VR
goggles in Litchi's FPV mode so I'm sure $400-$600
DJI goggles will be better in many ways, So nothing I've said here is definitive and only the perspective of someone just starting to use
goggles myself (when appropriate).
