Construction of a hand-launched glider, Lucas Lepretre’s construction plan

Lucas, a friend on Facebook posted a video a few days ago of one of his constructions and the flight of a hand-launched “LLD” glider / DLG depron DIY “glider.

This glider is 80 cm wide and the plan is available on the Lucas’ you tube page. After some exchanges of messages to have some technical details, it is decided, I initiating the construction. I am all the more motivated that when resuming club activities, a member came to fly to the field with another launched hand and I loved it.

First step, printing and assembly of the plan and cutting of the parts on 3 and 6 mm (0.12 and 0.24 In) depron styrofoam.

The wing is made in 6 mm (0.24 In) depron and is sanded to give a profile to the wing. To do this, I have lean on the right edge of a table and I delimited the transition zone between the leading edge and the trailing edge.

The warhead is also sanded to give it a rounded shape. I added to the original plan of Lucas, an upper part to the warhead to form a cover above the electronics, which will be installed in the warhead.

A little decoration of the wings, with green paint for children, passed with a brush.

I then added 3 x 1 mm (0.12 x 0.04 In) carbon plates in the wings, the stabilizer and the fin to strengthen. The wing is glued with an 8 ° dihedral and the fin set in place on the fuselage beam. The latter is a 5 x 5 mm (0.2 x 0.2 In) hardwood rod.

I still have to cover the depron with a lamination film to protect it, to finish the assembly and to install the radio
