It will end up being the DA40's only. At my club despite the fact there is a difference of £18/hr between the new machines and the old cessnas, most people learning are on the new machines. The Cessnas are really only used for ppl hire, usually by PPL's who've held licences for years.
New machines 7-800 Hrs per year (Virtually all training).
Cessna's 3-400 Hrs per year (Virtually all Self fly hire).
One of the reasons more people don't fly the newer machines for SFH is that they cannot book them unless they try at least a month ahead. Every slot is filled in these, whereas in the Cessnas you could get a slot any day of the week you fancy.
