Hi,
I was trying to get better range on my Phantom 3 Standard, as I was getting fed up with RTH issues just as I was in the middle of filming. I have fitted the external antennae on the receiver and have put external Aomway "rubber duckies" on the bird. I also had the Magic mod to increase db on the 2.4 from the bird. I read that better range could be achieved with downgrading the firmware to version 1.5.70, so decided to try it. Using the SD card method, I successfully installed it, and DJI Go reported that update required and the version number as 1.5.70+.
I force closed DJI Go, and opened Litchi, which is my app i use to fly. I started the bird without props, and tested that the sticks did the right moves, and closed the bird down after powering off the motors by pulling down the left stick. Went to try a flight, and chose a deserted area, to be safe. Did a compass calibration (The IMU reported calibration not required) and started the motors. Lifted off, and immediately, the bird climbed a bit and crabbed, shooting off at full throttle and then full pitch! moving the sticks did nothing, although I had all green on the controller, and the sticks had worked fine when I checked without props. Tried to change to ATTI mode and back to try to regain control, but it was out of sight, and the video feed looked scary. Not wishing to panic, i waggled the S2 switch to try to bring it home, and the beeping confirmed, together with the message that it was RETURNING TO HOME. I could see spinning on the video, and after what appeared to be enough time to worry about battery, it showed up, but shot right past, at about 80 feet altitude ( I set 200 feet as RTH!) Still had no control of sticks. Tried another waggle of S2, and with pulling down on left stick and timing it right, managed to land it. The props however, would not shut down. I tried switching off and on the receiver and this made no difference, the props were spinning at a high speed, and it was higher than idle. I managed to gingerly reach right under the craft and pick it up by the legs, and continued to hold the left stick at the bottom indent, which should shut down the motors. Eventually, it did! The area was a field, no concrete, metal or other issues, and the compass cal was successful. I brought it home, and have now upgraded to the latest firmware via the DJI Go app, and it was successful. Later today, I hope to fly to confirm all is okay. Again IMU reported it does not require calibration. Will post to let you know how it goes. I guess in 2019, downgrading does not work favourably. Sorry this is so long, but had to warn in case others have same issues.
