I have 600 hours or so in the ' Plastic Rat '. It's good points are, the visibility is pretty good from the bubble canopy, and it glides ok.
The bad points are, it is very uncomfortable, the seats are non adjustable, it seems to suffer from an unusually high number of maintanence problems and the electric trim is crap. I didn't realise how bad they were to fly until I got my hands on a PA28 again. If you can find somewhere with a decent PA28 for training, I would definately go for that. I think Leading Edge at Cumbernauld may have one.
