Edgley EA-9 Optimist

Noted at Tibenham oh Thursday 18th September was the unique and interesting Edgley EA-9 Optimist Glider BGA4093 / HPJ.
It is constructed using a material called FIBRELAM which is a board material with fibre skins with honeycombe infil. Although other kits were constructed this is the only example to have been completed..

Apparently it is at Tibenham for an experiment this weekend by some University to attach 16 Electric motors and propellors to the wing leading edges

A couple of images were taken of it on the runway prior to an aerotow in normal configuration. It stands out from the crowd as it is bright green overall with yellow trim

Cheers! Hasn’t modelling progressed in the last forty years! Presumably the batteries are carried in the glider or possibly in the pylons?

Has the motor got an alternative primary function or was it designed specifically for this project as I can’t read the full name of the manufacturer?

With sixteen motors, this would be a push me/pull you effort? What kind of motors are they as perhaps they could be used on any glider?
