I would also like to add, as someone who has recently qualified as a PPL(H) and who did it full time that I would find some social cohesion between other students useful.
Whilst training, I found hovering v. difficult and navigation relatively straight forward. I was chatting to another student who was exactly in the reverse position and it was helpful to get their point of view as well as that from an instructor who learned to fly many years ago and probably in a military environment.
I also think it would be helpful to continue this post-qualification since the opportunities for helicopter pilots to meet are not that common.
I also benefited from the opportunity to see all aspects of the operation including police, air ambulance, film work and engineering.
Cheers
