Ok gents, started to sort out the FEJ wing servo trays (Flap Aileron) The parts are laser cut and when finished becomes a sandwich box between the upper and lower skin. This keeps the box from flexing and adds strength to the wing in the cut out areas. Very nice design, will try and get some pics up this weekend. Tip make sure you scuff( not sand) all the laser cut edges for a better glue joint, take your time to fit all the pieces in the proper position and you may want to add some glass cloth to the upper skin before dropping the box in. Well done FEJ very pleased. Almost forgot,some trimming to the wing openings may be needed to drop the completed box when finished.
