Pod and boom fixed pitch trainer based on the British micro-Mold Lark for 25 size engines.  Initial heads were for single blade mounting to give an element of lead/lag however, this had to be set up correctly and was especially critical for correct blade CG otherwise vibration and unstable control occurred.  To simplify matters the design was changed to a twin bolt configuration which locked the head and gave better handling.

GMP Cricket Developments

Cricket with Bell-Hiller head and collective pitch???

 The development of the Cricket included a prototype head incorporating Bell-Hiller mixing though J Gorman has indicated that a collective pitch head was not developed even as a prototype.  The above photo may indicate that perhaps this was not so though there are no proven details about the model.
