good job... keep it going 

Here is a somewhat different design & build from my usual composites

It is a profile pattern flyer made of epp. The plan was to have a large wing area without going big on span, hence a very big root cord. (structurally stiffer, less wt, aerodynamically less prone to stalling compared to a thin cord.. drag not being an issue). The elliptical taper keeps the LD right. 

The flying surfaces are 9mm flat plate epp (hotwired out of a epp block). It has some carbon strips embedded in the foam for stiffness and strength. Also there is a kevlar string rigging across the fuselage, wings and tail surfaces to prevent against twisting. It has live hinges in the aileron, elevator and rudder (no tape used).

A stunning looking plane AND flies beautifully, very steady and controlled in all aspects. .. it is also very rugged

Nice build.. and the biplane solution to the design constrain was good..

This flu is causing me a lot of problems, but we're slowly moving forward.

This kit has been designed and manufactured with the aim of ensuring ease of transport and speed of assembly in the field. The solution adopted by Nicol Iad was to create a central part of the wing that houses the landing gear and remains attached to the fuselage. At the ends of this part are the two spars, to which the two vertical rudders are glued, which support the horizontal stabiliser at the top. The fuselage, the central part of the wing and the rear part with the vertical and horizontal rudders remain permanently assembled; in the field, however, the two wing halves must be assembled, which are attached to the central section with carbon bayonets and reference pins. This allows the entire model to be transported in a car with reduced bulk and easily assembled in the field. However, in my opinion, attaching the two wing halves remains awkward, as it is done using a through bolt on each wing half, supported in the wing structure by a block of plywood locked into the spars and ribs at that point. To attach the wing halves, everything is assembled, the bayonet and bayonet holder are drilled at the same time, and the through bolt or screw is inserted. No problem, except that it is clear that once the bayonet has been removed and the wing taken off, the next time we assemble the wing halves, we will have to match the two holes by rotating the bayonet, which is not easy. Everyone here can find the solution they prefer.

I am interested in purchasing the FrSky Tandem X20S and would appreciate any information regarding its availability from Indian online retailers.

That landing was in 2014!
