Life in the AAC
Life in the AAC is much the same as the rest of the British Army although some might say the AAC are a bit less rigid and more relaxed than some other corps. That's not to say that they are in any way unprofessional as the complete opposite is true. Pilots do get separated from some of the more mundane tasks but they are usually busy doing aircrew specific tasks. They may get to crash out in a tent as they need their sleep but in terms of being treated 'better' just because they are aircrew....not really.
What you need to ask yourself is why do you want to go to the AAC? If you just want to fly helicopters then just apply for Pilot selection whilst still in the RE as anyone can apply. You don't need to be in the AAC to apply for pilot selection it's Armywide. It was for full screws and above when I was there but it may now be Sgt as a minimum? Flying is fun no doubt about it but after a few years it's just a job. Fun but still a job.
Why not consider retraining as a REME helicopter technician and then at least you'll have a good trade when you get out if the pilot course does not work out and you can have a good close look at being a pilot in the process?
My advice, go for it. However, have a fall back position if you don't make it through selection or the Pilot course itself. Don't hang about either because there is an upper age limit on Pilot selection which used to be around 28 years old.
If you don't like the RE any more then bug out fast and do something you like because lifes just too short .
Good luck
