Question, did you fly with Aerofan.
I for one am extremely picky when it comes to aircraft, i also feel i am in a position to comment on both Aerofan and Aeromadrid, as i am currently training with both and have been for the last year. I am also from the UK, have flown in the USA , UK, and Spain.
Aerofan aircraft are NOT IN A BAD CONDITON!!, on the contrary, they are maintained on site and kept in a very good condition, i can only assume you have been flying brand new planes in the past with a pretty little interior and fancy cockpits!!. Did you fly with any of the schools you mention.
The school is generally very good, and untill you have honestly flown with a few schools, you have nothing to compare them to. Aerofan run a good, highly efficient flight training school, at a very cheap price.Just look at the countless threads on here from UK trainees who have completed their IR Multi there.
Aeromadid are also a good school but expensive, also limited when they can fly.
You must have been unlucky with your instructor as there are 2/3 who speak very good english.
