Pod and boom general purpose helicopter for 40-50 size engines.  Reverted back to the layout of the original Falcon head as the 'collective de-coupler' had proved to be unsuccessful.  Came with red anodised frame and 'gunmetal' coloured head components.  Engine mounting was better than the earlier models but the lower frame section could still crack as it was not very substantial.  The 'plastic' clutch could also give trouble if not treated with respect on running up the rotor head.

Upgrade version of the 505 with the newer see-saw type head.

Falcon 505s build manual  -  Construction manual but without exploded view (combined with 505 and 707).

Upgrades for 1983 included a belt holder to stop it from getting caught in the clutch flywheel and metal servo mounts to replace the original wooden mount.
