Flew the T67A. Underpowered, poor roll rate for a semi-aerobatic aeroplane and most of the time during aeros you have to watch the engine RPM like a hawk. Very restricted 2 PoB aerobatic weight.
Nice to potter about in though - but a very small fuel capacity.
I gather later models have more power and a better aerobatic weight - but still the glacial rate of roll unless abused by 'flicking'. Some have a CSU, which makes aeros less hassle...
The Bulldog is a far better aeroplane all round.
