hits the ground. The toe of the wheel is used to compensate for this so that the wheel doesn’t try
and pull in or out on the leg as the plane taxis.
A camber angle of 1.5° (with the top of the wheel leaning slightly outboard relative to the bottom of
the wheel) is recommended for all models when unloaded.
Depending on the type of operation the aircraft is normally used for the operator may alter the
camber angle slightly
– i.e. if the aircraft is normally loaded heavily a slightly higher camber angle
may be used.
Toe-in for the main wheels is set at between 10mm and 0 mm. This is for an empty aircraft.
If adjustments are required, washers are used as spacers between the stub axle and the
undercarriage leg.
If a combined toe / camber adjustment is required a higher stack of washers is fitted to the bolt
requiring most adjustment.
After packing the wheel alignment must be checked again
– this can be done by dry-assembling the
wheel with packing washers but no flock and then re-measuring the aircraft
– taking care to pull the
aircraft forwards to allow the undercarriage legs to “set” to the new angles. Alternatively the wheel
may be re-assembled with flock etc, left to cure and then re-checked once the resin has dried.
If the wheel remains outside the given limits the alignment procedure above must be repeated.
