1d' - They are hanging on to 2 of the Robins: one HR200 and the aerobatic H2160(?). This is presumably to try and keep some ex WA pilots happy and to give them an aerobatic aircraft.
The plan appears to be to standardise on PA28 Warriors with an Archer and a Saratoga also being available. Pilot Flight Training (PFT) had ordered two Cessna Skycatchers to replace their old C152s and that plan will still to go ahead.
As for name changes, the plan appears to be that eventually all the various companies will trade under the Aeros banner, but whether they will remain financially separate remains to be seen. Company practice seems to be to transfer the ownership of the aircraft to their own leasing company, which then leases them back to the flying schools/clubs. Apart from protecting major assets if a school folds, this will also give flexibility in terms of how the fleet (currently of 20 aircraft) is deployed.
Hopefully, the staff of both schools will be OK - this is not a good time to be looking for work.
