=======Simchair MKIV collective twin throttle lever body with tactile mark detents======= This manual describes the process of building a twin throttle lever body, with interchangeable heads, and a physical idle-stop detent latch. This manual was ported from the MKIII version, so you will see the MKIII collective base in the pictures. (Please ignore this). {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181202_215744-e1544001291605.jpg?300}} ====Components==== * 1 x 200x10x10mm aluminum square pipe * 1 x 105x10x10mm aluminum square pipe * 8 x M3x30mm screws and nuts * 1 x M3 x 35mm screw and a nut * 2 x M4x80 bolts * 2 x 16K1 linear 10K pots ==== Repository path ==== simchair4_models\printable components\peripherals\helicopter\collective lever\b_lever bodies\single throttle ==== Assembly highlights ==== None. ==== Assembly Guide ==== 1. Assemble the collective base MKIV using a 200mm piece of 10x10mm aluminum piping. {{http://hc625ma.org/wp-content/uploads/2019/07/IMG_20190705_112425.jpg?300}} 2. Install the decorative cover onto the 10mm tubing. {{http://hc625ma.org/wp-content/uploads/2019/04/15541397255194625171969524346276.jpg?300}} 3. Press-fit an M4 nut into the socket in the throttle 1 frame part 1. {{http://hc625ma.org/wp-content/uploads/2019/04/15541398787665677670460669330765.jpg?300}} 4. Insert a potentiometer into throttle 1 frame p1. 5. Put the throttle frame part 1 onto the 10mm tubing. Drill holes in the 10mm tubing, through the holes of the frame part 1. 6. Press-fit nuts into their sockets, insert 2 M3x30mm screws. {{http://hc625ma.org/wp-content/uploads/2019/04/15541427865304986091988611256535.jpg?300}} 7. Route 4-wire I2C cable and a 3-wire pot cable through the lever. This step may require some patience depending on the wires being used. {{http://hc625ma.org/wp-content/uploads/2019/04/15541431486518527466353623168875.jpg?300}} {{http://hc625ma.org/wp-content/uploads/2019/04/15541431906525001069622652028848.jpg?300}} 8. Solder the pot wires, and route the I2C cables through the cable channel, in the throttle 1 frame part 1. {{http://hc625ma.org/wp-content/uploads/2019/04/15541453256243437207042185727892.jpg?300}} 9. Turn the pot fully to the left, then just a notch to the right. Put the throttle grip on (if required, make the hole a bit wider, or squeeze the pot knob a bit, with pliers) in a way, that it will be in “Fully Open” position (See the picture below). Please make sure that the pot is able to rotate freely. {{http://hc625ma.org/wp-content/uploads/2019/04/15541463688991825727795946775650.jpg?300}} 10. Insert a piece of aluminum pipe into throttle 1 p2; drill holes and insert screws. 11.Route wires through cable channel and press-fit throttle1 p2 onto throttle 1 p1 {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_014427-e1543675212169.jpg?300}} 12. Tighten throttle 1 frame parts together with m4x80mm screw, choose a straight one {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_014732-e1543675283954.jpg?300}} 13. Press-fit m4 nyloc nut to throttle 2 p1 {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_021649.jpg?300}} 14. Route cables through and attach throttle 2 p1 {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_023020-e1543675435815.jpg?300}} 15. Drill holes, insert screws into throttle 2 p1 16. Pull throttle 2 pot wire out of the cable channel and solder it to the throttle 2 pot 17. Attach throttle 2 grip {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_025841.jpg?300}} 18. Insert the aluminum pipe into throttle 2 p2; drill holes and insert screws 19. Pull I2C ribbon cable through throttle 2 p2 and attach throttle 2 p2 20. Fix throttle 2 halves together with an M4x80mm screw {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181201_033337-e1543675668986.jpg?300}} 21. Pull a piece of ethernet cable through the I2C connector part, cut and solder I2C ribbon cable wires to it {{http://hc625ma.org/wp-content/uploads/2018/12/IMG_20181202_183639.jpg?300}} 22. Solder the 4-wire I2C cable to an Ethernet cable. ETHERNET WHITE-ORANGE -> I2C HEAD CABLE WIRE 1 (+5V) ETHERNET ORANGE -> I2C HEAD CABLE WIRE 2 (GND) ETHERNET WHITE-GREEN -> I2C HEAD CABLE WIRE 3 (SCL) ETHERNET BLUE -> I2C HEAD CABLE WIRE 4 (SDA) {{http://hc625ma.org/wp-content/uploads/2019/04/15541543801959180984975633657129.jpg?300}} 23. Route an Ethernet cable through the hole in I2C connector cover part. 24. To secure the Ethernet cable in its place, use some hot glue. {{http://hc625ma.org/wp-content/uploads/2019/04/15541547885343836952077109516302.jpg?300}} 25. Put the I2C cable housing onto the lever. 26. Solder the cables to your Arduino Pro Mini board, as follows: THROTTLE POTS AND I2C HEAD CABLE +5V -> Pro Mini VCC THROTTLE POTS and I2C HEAD CABLE GND) -> Pro Mini GND THROTTLE 1 POT SIGNAL -> A1 THROTTLE 2 POT SIGNAL -> A2 I2C HEAD CABLE SCL -> PRO MINI PIN A5 I2C HEAD CABLE SDA -> PRO MINI PIN A4 27. Put the lid onto the housing, and secure it with 4 M8x70mm screws. {{http://hc625ma.org/wp-content/uploads/2019/04/15542139378672177653029232012817.jpg?300}} 28. Please check that all of the cables fit snugly inside the enclosure, and nothing touches the magnet. Then you can close the hatch. {{http://hc625ma.org/wp-content/uploads/2019/04/15542140210722343886838281603012.jpg?300}} {{http://hc625ma.org/wp-content/uploads/2019/04/15542140803231523564079974054966.jpg?300}}
