Kramers tricopter step by step

Kramer's Documentation - hopefully a little easier to understand

• Legs
  • sanded Legs
  • Assemble Motors
    • attach the bottom braket
    • get counter sink side correct
  • Attach 2 non*servo motors to legs
    • opposite side of screw holes
    • align wires with opening
    • use small cutout to enclose wires within leg slot
      • could glue
    • zip tie in place

• • • Zip tie and connect speed control
    • will need to determine direction after build by running the motor and noting direction so don't make permanent

• • drill and file 3D printed gimble mount
    • use a screw and glue the end to make gimble pivot

• • • use super glue
  • screw motor on 3D printed mount
    • may need to drill to fit
    • align wires away from base end

• • Attach servo
    • use drill to reverse counter sink screw hole to get a flush connection
    • cut two edges of servo star to fit
    • ensure full range of motion and attach star to servo
    • superglue to gimble

• • Attach gimble and servo to leg
    • Found out I made a mistake in how the wires were aligned with cutout on leg
      • inscrewed and screwed
    • use zip ties
    • used super glue for spacer after zip tie

• • zip tie and connect speed controller
• Put the screws in a center piece and attach legs putting the gimbled leg in the center
  • use shorter 1 1/4 inch screw on inside for gimbled leg
  • attach so that the motors face down and the wires are accesable

• connect wires together in middle using solder and speaker wire
  • pigtail all negative and positive from the speed controllers
    • cut and strip black and red wires
    • cut and strip speaker wire
    • cut shrink wrap and solder wire red to red black to black

• • • lighter for shrink wrap
    • combine all neg and wire to neg for final wire
    • do the same for pos
    • don't forget skrink wrap(large)
  • Extend all control wires
  • only the white wire from the two legs without the gimble
  • all three from the gimble
  • leave about 4 inches past the hole through the center section to the top
  • takes a while; don't forget the shrink wrap
  • attach the top plate
  • I messed up the side I soldered the large wires and had to flip the legs to make the bottom plate the top

• • as you can see here, I ran both sets of wires out of the battery side. This is wrong. The control wires go out the top.

• Bottom plate -
  • attach velcro to battery and bottom plate
  • finish the battery velcro attachments

• use 2ish inches screws to attach plates

• apply foam to top plate where you will place flight comp
  • use super glue to attach comp
  • mini usb facing plate cutout

• • attach rough piece of velcro for transmitter
• hook up connections

• Download clean flight and get ready to test
