Building Your Double Trouble

18. Bolt the top wing in to position on the centre struts using the M3 x 12mm cap head bolts and

washers, these can be fully tightened at this stage (if you wish you could fit m3 nylock nuts for added

security but this will add to the assembly time at the field but a good idea if you are leaving it assembled)

19. Screw the outer wing struts in to place also using M3 x 12mm cap head bolts and washers but do

not fully tighten until the bottom wing is in place. These should rake backwards towards the tail.
