I'm not normally one to go on about safety but you seriously need to reconsider your flying methods and procedures.
Twice now you've lost control of your models with resultant fly aways.
The first one possible landed on a main road. No need to say anything about possible multiple injured people from traffic accidents.
The second landed in a football ground which was very luckily closed. But could have hit a person, on top of that rather stupidly you've put your name and number on it. Had it struck a person you'd probably have got a friendly nock on the door off the local coppers.
Regardless of circumstance, improper setup, or third party involvement both times you were the operator of the machine and as such would have been liable for injury or damage to persons or property.
Can I suggest you take the time to read the BMFA and civil aviation guidelines on operation of model aircraft for fpv use.
Take extra care or your gonna get bent over good and proper.
