I learnt at Cabair 19 years ago and have not flown with them since as they are just too expensive. A friend has been trying to learn to fly a helicopter with them buit about 50% of his lessons were canecelled to to unavailability of machines or instructors!
I have two friends who are learning with Firecrest and are very happy, and Flyteam no longer exists after Disley became involved.
Declaring an interest, I have an aircraft at Elstree and in spite of the fact that it's (Elstree - not the a/c!) a bit tatty in places it's friendly and compared to other places quite cheap.
It's all about chemistry. Give Firecrest a try and if you like them go for it, and pay for say ten hours at a time.
