If you feel confident doing basic manoeuvre with the TG and now you feel confident landing without it. Why go back...?

I remember that the first flight I remove it, I was pretty scared. now when I help newbie setting up their heli, I can't imagine it was that much scary! hehe I seems so easy after a couple of gallons only.

The only rules that you should check is : Do it at your own pace. You could stay with your TG for a full year if you think you need to.
