JYNX 4.0: This is JYNX glider designed by RCPLANS.nl . Now a days I am working on it and modifying it for electric motor powered. I am attaching whole plans of this glider. Totally made of depron foam and low cost plattform for APM.
The JYNX is a depron flying wing glider, designed for sloping. It's a simple build, which took me a week to finish in the evening hours. The JYNX has a 15% symmetrical airfoil, which is created by folding the wing from the leading edge around a depron spar. there are no carbon fibre reinforcements used, yet the wing is very strong and stiff. This plane is light on the budget too, as it uses just two cheap 5 gram servo's, a 4 channel receiver and a small battery.So far the prototype has flown a few hours, in which I've experimented with the center of gravity, control throws and reflex. You can find the results on the plan. Keep in mind that reaching the indicated center of gravity will mean you have to place the receiver and battery at the back of the fuselage.The JYNX has had a good number of pretty rough landings, but I haven't found a single scratch or crack. This is a very durable plane.Finishing has been done with clear packing tape used for masking, acrylic paint applied with a brush, and a dry paintroller to absorb and spread the paint. The results can be compared with airbrushed paint.The available space in the fuselage is quite limited. I'm still working on a version with a brushless motor, and might release a new plan for a slightly bigger fuselage soon.
