Evening Woodsy,I like training with the buddy box because if the plane is headed toward people ,pit area,houses or the sun I can take control before a major problem arises and someone or something is hurt,also the take over time is so fast that I can let the trainee work out the problems if any should happen,I'll let the plane alone until the last minute before I take control. I find the least amount of times I take control the sooner a student becomes a pilot,each instructor is different,if the student isn't happy with the instructor then get another instructor. Club size doesn't matter with the buddy box,here some of the students bring there own buddy boxes to train on.
