First is the ugly one. ZK-AMW is an Aeronautical Corp Aeronca 100 Ultralight. Its engine is a massive 36hp [wow!]. Apparantly it still holds the record for the lowest powered aircraft to cross Africa. You could probably run faster :-) Oh yeah - that ugly thing sticking up is part of the aircraft. Having said all that, it would probably be fun to fly anyway!
Anyway, the rest of them are:
EDR is a Jodel D.11
EEF is a Gardan GY-20 Minicab Ultralight
PKT is an Alpi Aviation Pioneer 200
NDI is an Airborne Outback trike
