Ok and thanks, plane is a powered glider, flying weight is looking like it will come in a 1.7kg with 3S battery, wings are XPS foam core with balsa skin, wing joiners are 10mm woven carbon fibre tube set 10cm into each panel with solid 0.312” aluminium bar 20cm long inside. It’s a no slop fit of the bar into the cf tube. incidence peg is to the trailing edge side and is a short 4mm steel tube.
