24.1 Airframe

24.1.1 Dihedral and washout
The following specifications are intended as a rough indication of the correctness of
the alignment of the wings. Unless there is a noticeable deviation from these, such as
the presence of anhedral or wash-in, any concerns will be addressed at the test flying
stage where the use of different-length lift-strut end-fittings can be used to adjust the
wing alignement.
a) The dihedral should be around 1.2 per wing: a straight line between centre of
the leading edge tubes at the wing tips should be around 10cm above the
same position at the centre of the cabin.
b) The washout should be around 1 at the wing tips compared to the wing roots:
this corresponds to a twist upwards of around 2cm of the height of the trailing
edge over the chord of the wing, from root to tip.
If this is grossly wrong it is likely that the internal bracing cables are not
taught. If either cable is loose the turnbuckle should be tightened. If one
of the cables remains slack whilst the other is tight it may be that the
covering is not properly seated on the leading edge, requiring removal
of the wing covering and refitting as per the instructions.
24.1.2 Jury struts
a) With the wing properly mounted and aligned, the jury struts can be made to fit.
Do not fit the jury struts before the aircraft is completed, as this will
change the required lengths significantly and cause the lift struts to be
pulled out of alignment.
