Very nice
but 100g thrust on a 320g all up is likely to be pretty, how shall I put it, marginal?.

well originally, it was powered by 2 brushed motors on a 3 cell, but the way i tested thrust was basically point the nose downwards on a scale, zeroed the scale then hit full throttle.

Was able to do a flight test today is some windy conditions, ended up stalling the aircraft and broke the vertical tail, I'll post up the crash pictures but here is a link to the video, luckily the aircraft frame cost only $50
