My experience with the prop guards was not good and I immediately returned them. I will be flying in areas that if an incident happened people and property would not be damaged or in danger. I have been in the R/C industry for 20 years so I can fly.
Hovering creates a down wash reducing lift as the air above the blades is removed. It also becomes less dense and further hampers air density reducing lift. The hotter it is the thinner the air density gets, less lift, why places like Arizona (118 degrees) have to stop landing and taking off planes as the air is so thin they just drive off the end of the runway.
In a real Helicopter they do NOT like to hover in the same spot for very long and move around or in any direction other than staying stationary. Helicopters with large blades and lift create a huge down ward air flow. This reduces the air pressure and lift, basically they create a whole and fall from the sky due low air density and no air to create lift.
Air disruption of the blades as well as wings on planes must be smooth, if they have even the smallest nick or dimple the size of a marble on an airliner will be grounded. It creates turbulence, reduces lift for the next blade as it passes the disrupted air. The prop guards disrupts the downward airflow (consistent lift) and creates back wash up into the blades disrupting the clean air flow of the blades. The flight stabilization system and GPS is trying to compensate for this instability along with YOU trying to control it as well. Thus you have a very twitchy and difficult to control drone and will likely end up in a very rough landing if not crashing it.
I put the prop guards on and they lasted two flights, one was at 20 feet in a field on an obstacle course setup to hone flying skills in low level flights. The drone was very unstable, flight was on the ragged edge at best, smooth flight changes in altitude and controlled maneuvers were jerky, erratic and in three cases near crashes and one crash when it rolled over falling 7 feet on its lid. It survived!!!
High altitude flight, first lets just say having the prop guards visible in 30% of the video was not going to work. The flight was erratic, flight time was reduced due to drag from the guards and flight control was jerky. Landing was nothing short of a lead brick, also, every take off was off balance dragging one side of the skids and not a straight up take off. Every landing ended in the drone tipping over on to one side resting on the prop guards.
I removed the prop guards, everything went back to normal, straight up take off and landings, smooth flight control, increased battery time. The obstacle course was clean and smooth as my proficiency on the course and time gets better.
These were OEM factory #28 prop guards from DJI, not some off brand. I will encourage anyone to NOT use them as it will hamper there ability to fly and become better pilots and worst case, crashed drones.
