I find it strange that you did not say Citabria, you specificaly said 7kCAB and no one has picked up on it.
The 7KCAB is effectively a mk1 Decathalon, being the link between that and the Citabria.
It has the shorter wing for improved roll rate and no flaps, it also has inverted fuel and oil as standard.Its a much better and totally different animal to the earlier lower powered Citabria models.
As an ex owner of a Cessna 150 aerobat and a 7KCAB I can tell you there is no comparison.
The 7KCAB rates amongst my alltime favourite aircraft.Compared to a CA150 it is a far more capable aerobatic machine, it is a better tourer, it is better short strip, better rough field and will even tow gliders. I have owned 90 aircraft, as an all rounder it is the best a/c I have ever owned.
As they are rare in this country I imagine if you have one in mind it is probably my old one.
PM me if you want more details. If it was on a permit I would probably still own it after all these years!
