I built my Cularis and found an immediate problem with the way the wing servo plugs are glue fitted to the joiner parts.(Good idea but not good enough in this case) Wiggling the wings on the finished model immediately caused servos to jitter or not work,this is because the plug in system is not man enough for the job,the small contact area of normal servo plugs and sockets does not offer a good enough contact area for this kind of use.. The solution was to cut out all the glued in plugs (a real pain !) and use normal flyleads accessed through a hole cut in the fuselage wing seat and the system is now 100% reliable. Just glad I didn't attempt to fly it first ! I sent my comments to Multiplex via my kit supplier (SMC) and now understand they have a revised system for later kits but I don't know how good it is. My advice..dont be tempted to use the glued in plugs and sockets,use flyleads.!! Other than that,the kit is very well presented and flies very well,the crow braking system works a treat,but as I only had one mix available (used for the crow brakes) you will find that you will have to fly it using quite a lot of rudder stick together with ailerons. Tip: the "Buttons" that retain the wing need a bit more downforce to ensure a good "click fit",the solution to this is to pack some hard foam rubber above the button end in the fuselage joiner system,this will force it downwards and ensure a good click fit in the wings everytime. Still prefer flying my Easyglider though ! (If you saw the stony landing sites we have here in sunny Spain you would understand why..no gentle grassy slopes here !)
