  1. I'm working on a Hurricane (based on the Tony Nijhuis plan) using a similar method, but using half formers and expanded polystyrene - it's much lighter that the blue foam I used for a previous build of the same model. What is the black foam you are using, and how does it compare weight wise, please?
  2. Using a hot wire to cut holes to mount the servos in the wing is fairly easy (if you have cut foam before and have the gear to hand). To run the wires, just cut a slot from servo to fus entry point using a sharp blade and a straight-edge and push the wires in edge on.
  3. Almost there. Getting a high power brushed ESC is nigh on impossible unless I use one designed for boats/trucks. These give a centre off and reverse function. Given that the Herc can actually taxi backwards this has its attractions, but has a few attendant problems. I went for two 30-amp Turnigy items, one for each wing. Again, this isn't ideal, but connecting two inners and two outers would involve digging holes in the wing to modify the wiring, which I am loath to do. Two ESCs running at half power or less most of the time will get warm, so they are in a box with a CPU fan screwed to the end. This is mounted on a foam block in the base of the fus, with the Rx close to it. All seems to work well. Painting is finished, and I only have details of the battery placement and hold-down to sort and we are ready to go. One of the positives from the rebuild was finding that the elevator servo was faulty, giving a slow but steady runaway of up elevator, so perhaps the crash wasn't all my fault after all! ESCs in box with fan. Installation looking a little bit tidy. Ready to go.
  4. Working on the U/C. As it's standoff scale (!!) I decided not to model open U/C doors, just dig a hole in the polystyrene and let the wheels in. I also wanted to make the U/C removeable for hand launching - one of our flying patched is a bit rough for 70mm wheels to handle. First I had to size up and create the axles with wheels, then make a frame to hold them. This assembly fits to the bottom, held in place by four screws going into blocks gorilla glued into the cut-out on the bottom of the fus. Assembly in place (no screws or axle clamps at this point) Doesn't look to bad at this stage. All I have to do now is get the glass cloth and varnish on the go to add strength and create a surface to redo the paint scheme.
  5. Replaced the 5mm dowels to be used to hold the wing to the fus. Added a ply former to the fus and marked hole positions to match the wing dowels. Trial fit of the wing..   Edited By Toni Reynaud on 02/11/2020 21:08:05 Edited By Toni Reynaud on 02/11/2020 21:10:11
