  1. Hi Phil, saw that - now it's in September (hopefully) even I won't have an excuse if I'm still trying to finish the model the night before. The only thing that maybe a show stopper on the build is not been able to get hold of paint if everthing is closed down. I've also remembered that I haven't yet ordered the canopy so will have to contact Steve at Vortex to see if he is still working in the present situation. Dirk, I don't think drawing up and 3D printing parts is as impressive as the artistry involved in producing your fiberglass speed brakes. I've just started planking the fuselage so that has sorted out the social isolation requirement for the next week. Hope everyone is well and "enjoying" the home schooling.

  2. Before gluing on the top wing skin I needed to make sure I could find the correct position to create holes for the wing munitions release cable controls to exit. By laying a sheet of clear plastic over the unskinned top of the wing I could draw the position of the holes related to the root rib and leading edge. Once the top wing skin was attached I used the plastic sheet template to cut the initial holes and then used small files to carefully open up the holes to the required sizes. The ball connectors are not yet glue to the control cables which made glueing the top wing skin on a lot easier.
  3. The servo mounts can then be glued in position - hopefully flush with the top of the ribs. How it looks from below with one servo in position. The string is for pulling servo wires through the wing. and servo hatches in position
  4. The servo hatch supports slot between the relevant ribs. Pins are pushed through the mount holes and bottom wing skin. The hatch template is then slotted onto the pins protruding out of the bottom wing skin I then cut round the outside of the hatch templates and the hatches can be removed. and the hatch frames can be glued in.
  5. The Sabre build was on hold over Xmas and new year period due to a few other projects needing to be completed. Over the last few weeks I've got back to work on the Sabre. I lined the inside of the servo bays with fiberglass so that when the hatches are cut out they have some strength and retain their shape. I am mounting the HS65 wing servos so that the control rod will be at right angles to the trailing edge. I have created 3D printed mounts for them. On the right is the servo mount (that will be up against the top wing skin, centre is the hatch cover support frame work and left is a template to cut the hatch out of the lower wing skin. Below shows the same but with HS65 servo inserted.
