I think i anderstand what you are going throug, i have a smartass that just started working with me, and this guy can somtimes go on my last nerve, my advice would be to you ignore him, and if he keeps bs'n then you just got to go up to him and tell him listen if you want me to help you, i will help you, but you got to listen, if you dont want me to help you then plz. live me alone. I know my example is not releated to RC flying but i think we have the same problem.
