Is your son a RC pilot?????? if he is not don't forget the trash bag...for the toothpicks......
flying full scale is not the same as RC...full scale the controls are never reversed...but they are in RC....everything in RC is by sight...no seat of the pants flying...
Please don't be one of those I'm a full scale pilot...I can handle this.....flyers......usually the airplane goes down the runway lifts off begins a gentle roll one way or the other, never recovers impacts inverted.....the amount of land to fly over would not have mattered...it didn't last that long....
Don't get me wrong I truely wish you the best....but an instructor is the way to go......
