Incidence adjusters.
I have put incidence adjusters on both wing and tailplanes as this provides more trimming options later on. The rear wing adjuster is the 8mm Gator product. It is also marketed as an adjuster for boats. The adjuster bolt is M3X0.5 pitch giving 3 turns per degree incidence. The front adjuster is from 1.5mm glass fiber board.
This completes the wing and tail construction. The wings average 250gms and the tailplanes 67.
