If we're going to quote facts...
The last of the C150s the 'M' model had the same 'pre select' flap switch as the C152. Very early C150s had mechanical flaps as per a PA28.
The early electric flap C150s had the position indicator in the left A pillar. The switch is sprung for flaps down so only move when you hold the switch down. It would stay in the 'up' position which was handy on go arounds - if you want all the flap off.
C150s have 40 degrees of flap and C152s 30 degrees.
The FRA150L/M were Aerobats fitted with the Rolls-Royce O-240 130hp engine. There are a few around still - most were operated originally by AST at Perth.
There was a version of the C152 Aerobat called the Sparrowhawk which had a high compression Lyc O-235 rated at 125hp. They found this wasn't a successful motor though and there aren't many about - most likely none in the UK.
And I never did like lies, damn lies or statistics....
