Hi spanner, a chap in our club has one but he got from a third party so i can't give details of who designed it. The basic details are as follows 1. The fuselage join is approximately where the front of the "A" is on the side of the fusealage in the picture. Either side of the join is a plywood bulkhead faced with aluminium sheet, not sure on thckness but maybe 1/16". In each corner is a fixing, 4of, which comprise of keyhole slots in the front plate and mushroom headed pins in the back plate,so the pins go into the key hole and slide down to lock.Not to sure about this next bit,as I remember there was a nylon wing bolt going up from underneath to hold the two parts together.The two servo's in the tail half worked closed loop systems.These servo's were on a removeable sliding wooden tray for access and maintenance,but i cant recall how they were dismantled. The servo's are then conected with extension leads.
