But I believe its Hewland 2-stroke was its Achilles' heel .
Their sales effort wasn't much help either!
It was a long time ago but Lancs Aero Club had set about looking to replace its fleet of C150's. I was on the Committee at the time though in a junior role. A/c in contention included the ARV plus the V tailed Robin ATL. For some reason TV News became interested and interviewed the Club Chairman who stated his interest in the ARV and mentioned a fleet order for 5 planes.
The following morning the phone in the tower rang a few times but not from ARV, Richard Noble or anyone else involved with the a/c.
