I just finished my first biplane build. A BUSA 1/6th pup. The build itself was very enjoyable [aren't they all]. My auw including batteries [it's electric] is just under 6lbs and gives me just under a 100 watts per pound [more than enough I'm guessing]. Anyway I've flown numerous small electrics and a telemaster 40 and have gotten pretty confident with my 4*40 but have never flown a biplane. Any thing bipe specific that I should set up /watch for? Thanks for the help. Gary
