After looking at both videos this is just the kind of flying I love to do, nice gracefull aerobatic moves, then go on high rates and turn her loose and tear up the skies. I really am not that fussy if a head sticks out the cowel, or you need a differnt gear for a longer prop, as I fly for my own enjoyment 1st. havent decided on the type of servos or sizes needed yet as will have to measure the sq inches of each surface to deturmin that. I am up grading to 6v Ni-Mh this year with a MPI switch with led batt checker and recepital for field charging.
