BA 73 driver I know recently went the same road. Solo in seven hours, rattled through the course in no time.
Major differences - your hands are full all the time.
If you push the nose down when the engine fails, you're a dead man. (Or woman.)
You're going to love it.
I know a BA 74 FO who teaches on the R22 at Redhill. Send me a PM and I'll give you his phone number.
