Hi there! The stories about landings on the nose are true, it has happened quite few times in past. And true you can expect to fly a lot, and sometimes a lot more than necessary. Remember, the more you fly the more you pay, specially when it comes to multi engine training.
Sling2 is a lovely plane, but some of the aviation authorities around the globe don't seem to recognise that plane as suitable for training, which means the hours you build on that plane might be partially or totally discarded by those countries.
Same story with the Twin Comanche, used by the school for multi engine training.
If I were to choose a school, I would look at other options...
