Tail

The tail drive gearbox if factory assembled, however, it was dismantled so that the aluminium could be anodised black.

With the exception of the anodising this is how the tail drive gearbox left the factory.

The tail structure is largely pre fabricated. Both the tail boom and the shaft were well packed and arrived intact.

The tail drive gearbox has the ability for the gear mesh to be adjusted. The tail structure fitted without modification.

The drive shaft needed patience to be fitted so that it ran straight – each of the bearing holders have elongated holes to allow for slight adjustment to ensure that the three bearings are inline.

The universal joints at each end of the shaft were preinstalled.

Construction of the tail boom continued without modification.

The tail gearbox was factory assembled and the control mechanism was suitably smooth.

The tail blades and blade holders wer balanced prior to being attached onto the tail output shaft.

Installing the tail gearbox completed the tail assembly.
