Good job good idea but not a good design. not to throw rocks but by having bottom pick ups and no clunk system, aerobatic maneuvers are out of the question except for loops. little by little the UAT would be filled with air .even if you put a pick up line on each side the air would be the first to exit the tank as it's the path of least resistance also the tank being so far forward could lead to a very nose heavy airplane on take off and with a flame out things could be ugly. other than that something i agree,needs to be done about increasing the fuel capacity just my two cents. i hope it works out as i have one waiting to be built
