Falling down accidents, just like car crashes, are inevitable. Just a question of time.
To avoid falling down into water, try not to fly over rivers, lakes, resouvoirs or seas. Some people just fly them on land for sufficient long time before risking them to water surfaces.
The present quad drones may be as heavy as 1.2kg or heavier. Light to mild wind is ok. Do not fly when winds are very strong.
Choose flight path where you can rescue the down-drones after accident.
I have similar mentality after 1 flyaway and 2 falling down (all suffering from complete loss of control). Still practising and trying to find workable solutions to reduce some of the risks.
CE mode is up to 100M, while FCC mode could be up to 300M before video signal is lost.
I have just modified the camera signal antenna. Not sure how far it could reach. May be around 400-600M. At best may be 800M. But difficult to find horizontal testing ground with 800M flight path.
There are no absoption balls between Phantom 1 and the gimbal. Thus all the props' vibrations will be passed to the camera. This is a well-known drawback of Phantom 1.
The stock white props may also be not balanced. Most people do not test the props' balancing at all.
8 out of 10 stock or CF props are not balanced. The factories do not test them either.
Post-processing (eg. stablization) is required to minimize the jello/vibration/wind effect. Yes Vision does not have obvious jello effect, but vibration/wind effects are there, since the stock gimbal does not help to reduce these side-effects.
Luckily, stablizaton cures most of these defects.
