After a couple foolish indoor mishaps on my part, my best indoor setting is "OFF"
OK... Inside Job Done - Success.
My main concern was the dreaded "Fly Away" which I have had a couple of times flying outside.
Because we legally have to have a spotter within our licensing laws I have never lost a craft.
When a fly away occurs you simply must be able to see the craft as its functionality goes crazy, and if this happens inside you're stuffed.
With this in mind, not having an ATTI mode was a little concerning with the mavic
P2. I have flown a lot inside with a P3 in ATTI mode with no issues so I took HoozierDroneDaddys suggestion and went with the ATTI hack. I would really love this option added as standard on any future drones.
There was metal everywhere and in the standard P mode I was getting GPS going on and off along with compass errors. Went to ATTI mode, still got a couple of compass errors but all was fine for flying, as soon as I was a couple of meters off the ground there were no further compass errors. Obviously had my craft set to hover if there was an RC disconnection. The thing to watch out for is if you hit RTH in ATTI mode (which you shouldn't ever do inside) the craft will switch to use GPS and attempt to RTH as normal... setting it to RTH at current elevation is a good idea if there are no obstacles.
Inside there was a slight airflow that you could not feel that certainly moves the craft around so you need to be fairly experienced as your instant response of correction needs to be in the right direction. Inside there is NO ROOM for error. The day before my flight I went out to a very open area on a strong windy day and went to ATTI mode with the
MP2 to check out the craft responsiveness and my flying reactions. I tried to keep the craft 2 meters off the ground just in front of me while rotating the craft 90 degrees one way and then another the 180 etc etc. If you can keep your craft relatively in the same position each time then you are ready for ATTI inside flying.
As the craft moves around you must keep your eyes on the craft to control it correctly. I had my spotter recording when needed and adjusting camera settings etc... I did not look at the screen at all, I was directed by the spotter. One last thing, I was always reminding myself of " a safe move to the most open area" in case anything like a sudden strong airflow eventuated..eg hard left and down is safe... I had someone come in the door and just the extra airflow pushed my drone towards a wall... so, hard left and down in this case was an incident avoided.
Always better to be prepared for anything.
So there you have it a success, all went really well, thanks to all for your input.
Fly Safe
Cheers
