Lidl Glider - Inverse V-Tail conversion
Description
This is my first Lidl glider conversion. I wanted to create a unique look and could not find any inverted V-Tail configurations online. Here you can find all you need to copy this conversion. There are a number of 3D printable parts and a drawing for the tail parts in 3mm medium to hard balsa. The spar holder tail part should also be printed mirrored so you have a left and right version. There are breakaway supports to help it stay upright during printing. Print 6 pushrod guides Print 2 spar holders for the wing Print 1 V-Tail top joiner Print 1 set of motor mount parts You will need: 2x 350mm carbon tube 5x4mm 3mm Balsa for the tail 6mm Balsa for the wing extension and ailerons 4x rudder horns self tapping screws to attach the rudder horns some 1.2mm steel pushrods 4x 9 gram servo's 25 gram glass cloth for the wing G4 polyurethane to apply the glass (or similar 1K polyurethane lacquer) Alternatively you can glue carbon tubes into the wing to stiffen it. Racing drone motor with 16-19mm bolt hole spacing, I used a 2206 1900KV motor Propeller 4s 1300 mAh LiPo 5 channel or more receiver 25A ESC with BEC Some lead on other metal to balance it Magnets for the canopy My build order: -I cut the tail 35mm behand the wing opening and cut the fuselage in 2 halves to make work on it much easier. I made opening for all the components -Prepared the wing by lightly sanding. -Attached 20mm wide 6mm thick balsa extensions to the middle section of the wing and sanded it to shape leaving a nice thin trailing edge. -Marked the position where the tail booms should be placed. The spacing between the tail tubes is 270mm from centre to centre. -Mark the positions for the 4 servo's, see pictures -Cut slits for the servo wires. -Extend the servo wires so the will stick out ~60mm in front of the middel of the wing. -Cut and mill pockets for the servo's and glue them in place. Make room for the servo arm to be pushed flush with the wing so they don't stick out when glassing the wing. -Glass the bottom of the wing with one layer of 25 gramms glass cloth. Use a brush to apply the G4. Cut the glass cloth ~20mm larger then the wing and fold it over the leading edge, the wingtips and the trailing edge (only where the ailerons will be placed) using G4. -After drying, cut away all loose glass and lightly sand the top of the wing where there is glass cloth. Now apply glass cloth to the top of the wing in the same way as you did the bottom. Allow to dry and cut away all loose cloth. Inspect the work and if there are any air bubbles, just apply some CA glue and rub it in with a piece of plastic until its hard. -Cut holes is the glass for the servo arms. -Make aillerons from 6mm balsa tand sand into shape. Cover with covering film. Attach using CA hinges. -Slide the wing into the fuselage. The tricky part if feeding the servo wires between the wing and the fuse so you can pull them into the fuselage. This will take some patience! - Centre the fuselage on the wing and glue in place using CA. -Make the Blasa tail parts and cover them. I used the covering to make the hinges. See picture. -Glue all the tail parts together with CA. Glue the tail to the wing. The printed part sits flush with the trailing edge. -Attach rudder horns -Attach pushrods. There are some guide pieces for the tail pushrods. -Install the rest of the RC gear. Adjust the controls to you liking. -Balance the plane. My CG is at 53mm behing the leding edge Have fun flying!
