Humberella,
I have recently trained at Humberside with Soloflight. I started last Nov. and got my PPL after 47hrs. I am very happy with the training I recieved. The aircraft are all PA-28s (four of them), and I could pretty much book lessons as I had spare time.
The instruction is very good, and they have an experienced ground school instructor, who gets students from all over the north of England (upto ATPL).
I am not sure how you heard that they were in difficulties, but this is not true. In fact, the school buildings have just been extended to add a further 2 breifing rooms in the last month or so.
If you want to know anything further, please feel free to PM me.
Justin
