RE: emergency Parachute safety system
If there are guest of wind strong enough to be making you loose control you should not be flying. The cub should not be flown in winds over 8mph by a beginner. You just need to get better at flying under normal operating conditions. Trust me, once you learn to fly better, it's almost impossible to crash the cub, I have one. All the time and money that it will take you to make a recovery system ( although cool) could be spend practicing flying your cub or a sim. (such as Esky(a cheap but effective sim found on ebay)).
