Covaero
As I've said earlier, I'm very sad at the schools demise, being one of those who hire their PA28's - they patiently taught me to fly too. However, living South of East Mids, I have found "refuge" at the Coventry Aeroplane Club based at EGBE. Obviously, for those North of East Mids, it may be too far, but I can recommend the club to anyone who feels Coventry is not too far.
A very big attraction is the two new Warrior 111's in the fleet. Beautiful, low hours aircraft, well equipped (2 x Garmin 430's, electric standby vac pump etc etc) and based at a Club with good facilities - good bar etc!!
I have only done a couple of trips so far, one with their CFI (nice chap too) for a check ride, and one a couple of days ago to Gloucester. They do encourage Club members to fly together, and are happy for the aircraft to be taken for longer trips.
I have no commercial interest in the club except as a new member, but can recommend it for those who wish to fly new PA28's.
