MIA PVC Land Yacht RC Version. AKA as RC Land Sailer, RC Char a Voile, Carro Vela. This is one of various designs I did in PVC tubing. This one has a similar "T" shape main frame to the original aluminum  and smaller MIA Trike-a-Sail™, except in Poly or PVC Tubing.  The sail is a typical RC Land Yacht sail but made from thread reinforced clear mylar with Dacron edging and batten pockets.  What is neat on this one is the use of a double servo for the sail boom control.  One STD large servo was good in mild winds but for heavy wind sail control, I wanted double the strength and decided to use 2 servos for extra torque.  Both servos are mixed via the transmitter so that they both pull the sail at the same time.  

Not all PVC landyachts are the same. The trick is in the actual dimensions, moment arms, weight distribution and manufacturing details. 

I designed this MIA Poly RC Land Yacht on the computer and build it from that design. The Thumbnail shows the actual  CAD design from which I built this model.  All 3D printed parts were also part of the design with slight modification for the dual servo sail control. 

A second video will show the model running.
