You can fly with as little as 10, however there are others that will fight tooth and nail against this!
My 82+ hours of flying (4,920 minutes) and no issues. I've flow with as little as 9, but you need to be on your toes!
Don't over engineering your ability to fly at minimums!
Real pilots practice minimums, a "just in case" something develops out of the ordinary.
You can actually fly with only 7 when launching in Angle mode but before doing so you must recognize and accept that position stability will be severely impacted or non existent. Until the white light is flashing with the purple light the aircraft has no chance of being positionally stable, you have to maintain lateral position manually.
There’s a caveat to seeing the white flashing light in either Angle or Smart mode. The light indicates the system has the correct satellite count to make full use of the mode selected but it is not representative of having good position resolution. That only occurs over time with the satellite count depicted.
Any system that has sat for an extended period of time and/or transported a considerable distance to a new location requires an undefined amount of time necessary for the system to obtain position data adequate for low value circular error probability. Sat count alone does not assure a good position fix.
Launching and discovering your aircraft won’t hold a relatively stable position is indicative of several things. If you had just done a firmware update, check the aircraft telemetry broadcast at the left side of the screen. If it’s not continually updating, part or all of the update didn’t take or the system is not fully bound. Land immediately.
If you had performed a compass calibration incorrectly drift is possible. Land and perform another one. Do it faster than the last one.
If you had activated cruise control, accidentally or intentionally, you may have a continuous lateral notion command directing the aircraft you are unaware of. Typically the drift will be in only one direction. “Stir” the right stick to deactivate Cruise Control.
If you suspect drift is due to GPS because of a long period of non use, a new, distant location, or a firmware update you have two remedies to choose from; land and allow the system time to obtain better resolution, remain in flight in Angle mode at a height that permits obstacle clearance while you hover manually to allow time for better resolution. If you are competent with manual flight control this method can be good practice.
During any flight where positional instability is present, do not ever switch into or fly in Smart mode. Avoid use of RTH as it is dependent on a good position fix for both the aircraft and “home” locations to function correctly.
Never, ever, perform the first flight after a firmware update or compass cal in Smart mode. Smart mode absolutely requires a solid position fix at all times while also requiring a consistent RC signal. If you had a defective update or compass cal prior to launch, Smart mode is always the mode the bad stuff happens in.
For those just obtaining their first H, there is no need to update firmware before your first flight. Every firmware version for the H functioned well. One contained an altitude restriction but in no way did it impede good flight control. Yuneec does not require their aircraft be hooked up to the “mother ship” before the first flight. Yuneec products are “stand alone” and can be used out of the box without ever being linked to the manufacturer’s server. The H Plus and 520 had firmware issues out of the box but the H never has. If your purchase was a used unit and it was flying well before you bought it, it will fly well after you bought it. If it had issues you were not informed of it is far better to fly it as received to discover an issue than it is to immediately update the firmware, which provides the seller an “out” as a great many new owners have bungled the firmware update process, introducing issues that had not been present with the previous firmware. Determine what you have and how it functions before changing everything.
