About 10 years ago, a friend had the Ducted Fan set-up with the Toki .18 engine...(it looks virtually identical to the K&B and HPI )...it had a pull start like a car engine. The DF unit and tuned pipe came as part of a package deal, with an airplane kit...can't recall the name of the plane though? The kit manuf. might have been OK Models, but I'm not too sure of that? It was a Japanese kit, is about all I can be sure of...(I think
)
It was a cool looking little jet-like plane, but it built heavy, and after testing the fan unit, we found it wasn't all that powerful either...and eventuall my friend lost interest...never did fly it...
