*** I will be editing this post based on new information/comments*** DJI Phantom 2 Vision Plus is a fantastic, cutting edge product, but has had some serious concerns. It is advertised as an RTF (ready to fly) unit for "everybody". It is not. It requires reading the manual, watching videos, researching various topics online, and practice, but most of all, it requires switching the shipped software settings to another mode before flight (NAZA mode) in order to counter the loss of GPS signal during flight. In a nutshell, if your Phantom drops below 5-6 satellites during flight, GPS mode is cancelled. It will not hover in one position, but drift with the wind. Worse, the RTH (return to home) function DJI touts as a "failsafe" will not work. Many Phantoms seem to operate perfectly fine without the following steps, but more than a few "fly away". The following list isn't a requirement, but if you want to limit your long term risk of a "fly away", please invest the time and effort: When you get your Phantom, do the following: 1. Read the manual. 2. Watch the videos 3. Read this board 4. Charge your batteries 5. Open your phantom (plenty of YouTube video on this) and seal the exposed electrical connections with GE Silicone II (non-acetic acid formula). This eliminates poor quality control during assembly or just plain shaking a connection loose during flight. Not definitively needed, but a worthwhile thing to do if your comfortable with it. 6. Install the drivers and DJI Assistant software into your computer. Connect your Phantom. Test transmitter function, switch to NAZA mode, enable IOC, set height and distance limits, perform an IMU calibration, check compass variables are within normal limits. 7. Check winds aloft (if the winds exceed 30 mph at the altitude you are flying, your Phantom may not be able to fight them and will "fly away". 8. Calibrate the compass (and repeat prior to flight any time you change geographic area significantly). Place the phantom on the ground or a box, being careful to keep it away from metal (manhole cover,etc) or reinforced concrete, which can screw up the compass. 9. Inspect the prop tips and hubs carefully for cracks/damage. If you hit a big bug (cicada), or have bumped the props, they could fail during flight. Your Phantom will not be controllable and the NAZA flight controller will respond by trying to correct the imbalance in unpredictable ways. 10. Do not take off until your DJI FPV smartphone app is connected, the camera is functioning, and the app indicates at least 6 satellites and you are sure your home point is "locked". The RF (radio frequency) shielding of the Phantom has been observed (in a lab/small sample size) to be poor and can interfere with weak GPS signals. If the Phantom falls below 5-6 satellites during flight, it will drift with the wind, and the RTH (return to home) function will not work. Switch to ATTI mode using the S1 switch immediately. 11. Following take off, hover at 10 feet or so until the Phantom is stable and you confirm basic flight commands are functioning. Then ascend above the highest local obstacle (trees, houses, buildings, etc). 12. Avoid rapid descents, as this is known to cause VRS (vortex ring state). This results in the Phantom fluttering to the ground at high speed, despite full throttle. It is easily avoided by moving in any lateral direction during descent (right stick input). Be aware this may occur in hover as well, and that DJI prop guards are known to increase the likelihood of VRS. 13. Learn how to use the various IOC modes and flight modes in a big, open field with soft grass. In the event of any erratic behavior of the Phantom, switch to ATTI mode and land immediately. If you take the time to learn these 13 steps, you will eliminate a vast majority of fly away concerns. You still need to be concerned with motor failure, ESC (electronic speed controller) failure, and RF interference. They have not yet invented a flying machine that is simple and idiot proof. Chinese labor and manufacturing is cheap for a reason, as Quality control and worker skill is questionable. The P2V+ is fragile. A bump or hard landing could effect the NAZA flight controller, its sensors, or especially the gimbal/camera. If you are new to this, buy a $400 Phantom FC40, which takes a beating before you bang up a $1369 P2V+ that does not (at this time) have a good replacement part or repair availability. You could always sell that FC40 and recoup at least half of your investment. Other safety measures: Repeat Advanced IMU calibration after any "hard" landings or bumps. Perform a compass calibration after IMU calibration. Purchase a "Getterback" water retrieval device and mount to landing skid. Purchase a GPS tracking device to mount on your Phantom (many topics on this board about different ones). Purchase the third party FPV Boost app. Upgrade your antennas with FPVLR.com stage 2 kit to have a lower chance of connection loss. (requires some modification and skill). S1 and S2 switches are easy to inadvertently bump, be careful. Periodically check their function in DJI Assistant software as some have reported bad switches after some use. Write your name and number on the Phantom in case its lost and found by a kind heart. Emergency Check List: VRS: apply right stick input immediately If anything seems out of the ordinary: switch to ATTI mode immediately. Land immediately. Figure it out before you fly again.
