I managed a 40 deg flap takoff as an inexperienced PPL with the yolk still wet behind my ears. I'd forgotten to retract the flaps after checking their travel. The 150 was a good one and levitated into the air as I was heading straight into a 10 knot wind. It didn't want to go forward very quickly and I soon realised what I had done. I just eased the flaps up gently and she accelerated away with no hight loss.
I had an A150L which was an imported Aerobat with the Continental O-200. Lovely little thing. Shame that she was wrecked in a gale. The FRA 150 had the R-R Continental O-240 which is basically an O-200 with O-360 cylinders to take the capacity out to 240 cu ins. Huge improvement on the climb and makes it a more usable aerobatic machine. Rumour has it that the R-R built O-200s put out 105hp compared to the 100hp (on a good day) that was expected from Continental's offering.
