Even with the carbon fiber in the wing, the CAP 10 B or C would struggle to be competitive at intermediate today
I beg to differ! In the right hands, (i.e flown with skill and not relying on the aircraft to do it for you......) the CAP10 is still very competitive at Int level.
In the dim and distant past when I competed, the UK sequences were designed so that a Stampe could do Intermediate. Brian Lecomber even competed at Std level in a Sopwith Camel replica. together with guys in an RF4, an Airtourer, and Tipsy Nipper! All flown with skill and wringing the most out of underpowered and aerodynamically deficient aircraft.
But then it got easier and everyone bought an Extra/Sukhoi and got the pyizes
