Fagan EF5
 
Fagan-5-01
 
A 1977 hang glider, the EF5 is an Australian rigid designed by Ewen Fagan. Very similar to Manta Fledging, it was sold as a plan and kit by its designer. It was later (early 80's) sold by Skyland Kites, Qld, Australia.It was sold as a kind of kit, you could buy the machined parts, the cables and the sewn sails. The aluminum tubes had to be purchased on site.
Graham John had the company Skyland Kites and manufactured and sold a range of hang gliders from about 1975 to 1980 on the Gold Coast of Australia. He had an EF5 in his shop and may have manufactured a few.
 
Piloting similar to Fledge.The EF5 was mostly a Manta Fledge copy with a few modifications. Like all the older tip rudder controlled rigid wings it was a bit difficult to ground handle in wind as rudder application dragged the tips back - not down. Also roll lagged yaw a bit - ie the wing would yaw first then roll. But in the air it was much more responsive than the flex wings of the day (pre billow shift).It is reactive in pitching and quickly accelerates in dive. Put it in dynamic stall with a rudder engaged and one will spin: engage the other rudder and it comes out. If you gradually put it in stall with both rudders engaged, it will stop and descend vertically - a good way to lose altitude fast enough without gaining speed. When flying along the terrain with a wing close to the ground, using the opposite control automatically raises the wing close to the ground, with a control wing tips that does not have a conventional delta.
 
The EF5 12 metre could be chopped down to a 10 metre around. It liked the fast descent you could do by pulling both rudders on at once. It could do a breathtakingly fast dive and interesting spins.
