Captain Capstan, I've been in touch with someone from the group in the past but they told me I'd be unable to join under any kind of a no equity arrangement.
Stevelup, the reason is down to the increased level of responsibility for the airplane itself. I figured it may be useful to get some experience as a PPL before joining a group. I've also been told it may be useful to fly from somewhere that can offer a more structured service during the hour building for my CPL.
Having said that, I wouldn't rule it out completely. As you said, it is sometimes far more efficient financially. Are there any other groups like this at Liverpool?
