John Ridyard's scratch built ****** ******

Webmaster's Notes John has suggested :- "Perhaps, if you don't tell them at the outset, our members could try and work out just what aircraft it is."  Answers to  john@johnridyard.fsnet.co.uk

I made my own drawings from photographs and a side elevation downloaded from the internet, indicating the visible construction of the original - the fin is a real gem, and no other way of building it could be any stronger for the weight, which is as a feather.

The fuselage sides were built over the plan, with the position of the gear tray pencil marked on. The gear tray was built and the sides fixed to it. placing the structure over the plan, the cross and diagonal braces were glued in, then the rear deck formers and longruns

The forward part of the fus. was bent in to shape and doubled (twice) with sheet to hold the shape. The top of the nose is made up of sheets of 1/4", the 'fuel' tank from thin sheet over formers, as is the centre top section with the cockpits. The undercart is built using wire and light hardwood 3/32" x 1/2" stitched and araldited into a sub-frame which slots in.

With this in position the boxes for the end of the lower wing main-spars were built of thin ply and hard balsa and fixed in place, taking care to have equal angles. The wings have straight-grain pine mainspars and are conventional apart from the edges and tips being laminated with fine cane to give a smart (hard) edge and stiffness to the soft lightweight balsa.

The radio installation plan is to put all three micro servos in the area behind the undercart sub-frame where the couplings can be easily accessed via a hatch Ailerons on the lower wing will be operated via stub axels and levers engaging in holes at the inboard end of the control surface. These will give a wing warp effect!!!! Rudder and elevator will have closes loops.

P.S. I doubt there is a Prize for the correct answer.
