B7 frame consists of five groups


flat aluminum details and cnc machined aluminum connectors


specially made wing mechanization items and a little bit of fasteners


aluminium tubes with corners and carbon fiber products


Everything except special M3 fasteners is ready, it's time to make an assembly
At first I've tried to use a stopwatch to determine right time but then I gave up on this idea


Here you can see how my +7 connectors are used


two with a half hours and wing section is assembled


Intermediate weight is 340g (17g is weight of drill bits)


Plus ninety minutes and central part is made also. Its weight 270g


overview


Angles should be +7 on the wing and +8 on the stabilizer


While assembling I've found several details to improve, for example - my logo is made head over heels
