Thanks Ed and WEDJ.

The Aggrovator was kitted by a British company called Truline, I don't know how popular it was, I can only remember my dad's plane.
I had a Truline trainer and my dad was sponsored by a local hobbie shop that carried Truline, HP engines and Proline radios.

Next plane to "hit" the air is this unknow patternbird, it might be a british plane to.

Take care.
Joakim
