| LASTWOODSMAN | SIG Cabinaire | Parked | 11-Jul-17 13:07 |  | | Views : 374 | | LONGER MOTOR & TRIM TABS - Yesterday it rained pretty good all day long, and the sun came out in late afternoon, and was evaporating all of the water into the air = HIGH HUMIDITY. I took the 22" Sig "Cabinaire" out at twilight gloaming dusk, for some flights with a new, longer motor, of two, 20" long each, strands of 3/16" rubber (prop hook to rear motor peg is 13"). The plane had on the previous evening at dusk, been flying during "transition", after initial power burst, flying into quick descending, tight, steep-turn spiral dives, on the Right Hand circle flight. I tried to counteract this, by putting a small DOWN "tab", of file folder cardboard, scotch taped (it does not rip the tissue off when you pull off the tape), taped this tab, with a little downwards bend, onto the bottom trailing edge of the outward right wing, to raise the wing during flight, and another small LEFT "tab", with a little left bend in it, taped this tab to the left side of the rudder, to counteract the right turn a bit. It flew GREAT !!! |

| LASTWOODSMAN | SIG Cabinaire | Parked | 10-Jul-17 06:40 |  | | Views : 310 | | I then used a couple of notch sanders to make notches to hold the three 1/16" sq forward fuse bottom stringers that were busted up and removed. One of the three stringers is in place. |
| LASTWOODSMAN | SIG Cabinaire | Parked | 10-Jul-17 06:38 |  | | Views : 347 | | The pic shows the clamping plates in position, and holding tight, the glued up support plate. I was able to get the jaws of two strong clamps inside the fuse opening to hold everything together. All glued up and clamped in place. |
| LASTWOODSMAN | SIG Cabinaire | Parked | 10-Jul-17 06:36 |  | | Views : 367 | | I was able to double white glue that chunk of balsa, that was ripped out from the bottom of the forward fuse former, right back into its spot ( it slid right back in - press fit! ). I then made a 1/16" thick, slightly smaller, 3/4 size support plate (with the rectangular cutout for the nose block), to glue in behind that forward fuse former bulkhead for additional strengthening. The pic shows the support plate (with inked lines), sitting in position inside the front fuse former. I also made two clamping plates (either side of the fuse) - one for the front of the fuse, and one for inside the fuse, to hold the support plate in place while the glue dries. |

| LASTWOODSMAN | SIG Cabinaire | Parked | 08-Jul-17 18:58 |  | | Views : 353 | | I just tried using bigger rubber and I reduced the number of rubber strands, on my 22" Cabinaire, with great results. Instead of 4 strands of 1/8" rubber, each strand 13" long (the prop hook to rear motor peg length on the plan was 13"), which gave consistent 25 second flights, I then instead went to 2 strands of 3/16" rubber, each strand 15" long. I could really stretch the rubber very far out from the nose, using a winding stooge, and wound in 55 winds on my 15:1 winder which equals 825 turns on the rubber motor, and got my record, much slower, beautiful turning flight of 48 seconds!! Tthen I got greedy and wound 70 turns on the winder for 1050 turns, and when I put the nose plug on - the Rubber Motor BLEW UP !!! Tissue damage all over the rear end, and a big chunk (sitting on my glasses case), of the foreward fuse former, busted out, along with the bottom fuse forward nose stringers busted !! |
| LASTWOODSMAN | SIG Cabinaire | Parked | 04-Jul-17 13:38 |  | | Views : 343 | | 20 " Customaire bipe - The parts are now completely blocked up and fitted to each other. The two die crushed ribs were bigger than the laser cut ribs, and had to be sanded to the shape of the laser cut ribs - by sandwiching the two die crushed ribs between the two laser cut ribs, and sanding them equal to the laser cut ribs. Two W6 ribs are left over, and will be added after all else is glued up and dry. The twin W6 ribs in each wing have a 1/32" space between them for the wing strut attachment. I will fit a 1/32" spacer of balsa between them and then glue the rib twins. |
| LASTWOODSMAN | SIG Cabinaire | Parked | 04-Jul-17 13:34 |  | | Views : 323 | | 20" Customaire biplane build - the parts for the two lower "sesqui" wings are ready to be test fitted and held in place flush and snug (but not too tight) for slip fit, with 'parts-locating', balsa bracing planks, that are pinned to the building board. They will then be removed for "double gluing". |
| LASTWOODSMAN | SIG Cabinaire | Parked | 04-Jul-17 13:19 |  | | Views : 311 | | 20" Sig "Customaire" bipe - The completed Stab and Fin/Rudder have been finished and sanded to 320 grit. They together weigh less than one gram. |
| LASTWOODSMAN | SIG Cabinaire | Parked | 03-Jul-17 19:00 |  | | Views : 385 | | 22" Sig Customaire bipe - Stabilizer is now all glued up in with the parts in position, waiting to dry overnight. |
