Kramers tricopter step by step
Kramer's Documentation at end of day one 1/31/15 Tricopter Build
- 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 - [[File:Kramer's Tricopter Photo11.jpg][200px]] - 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 - photo 2 - drill and file 3D printed gimble mount - use a screw and glue the end to make gimble pivot - photo 3 - use super glue - screw motor on 3D printed mount - may need to drill to fit - align wires away from base end - photo4 - 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 - photo5 - 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 - photo6 - 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 - photo7
- 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 - photo8 - 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 - photo11 - photo10
