I have not flown Pattern for quite a while but I am sure the Tony F. you guys are disagreing with is a much more accomplished pilot than most on this site. Also has flown everything from drones to Heli's. Tony is also a very accomplished builder as well.If my memory serves me right there is a guy from Argentina that Tony had in his home in Miamisburg,Ohio years ago and both were building planes together. Tony I just found a Challenge 11 in the box and am going to buy it just to have it. Also just moved back to southern Ca. Where are you flying? Believe me if Tony says it....it is because he has done it. I would take lessons from him all day long.Just my opinon. I think Tony even won a championship in Australia once!!!
