I built this upscale o' an Estes Advanced Target Drone after buildin' a clone o' t' original and findin' that Excelsior made upscale decals in this size.  It was a little more challengin' than other upscales that Ive done, insomuch as I made t' body shrouds out o' 1/16th ply, and designed t' build it as a 3x24mm cluster while I be at it.  T' added motor mounts are parallel t' t' t' main mount in t' shrouds.  It came out a little heavier than I'd hoped, ya bilge rat, at 13.5 oz, but it should fly fine on 3 D12's or a single E30 composite.
