After searching and searching after the perfect tricopter V3 motor I ended up getting custom ones made. The results on the test bench were spot on! So I decided to build Tricopter V3.5 from scratch with the new electronics and while I’m at it, why not make a build log as well.
Sand the bottom wire holders with 180 grit paper (or something there about) This is so the glue have more surface area to grab on to and it ensures that the piece is nice and flat. Don’t forget to wipe the piece off after you’ve sanded it. Dust is glues worst enemy.
Squeeze the bottom wire holder and the battery tray together. Make sure the surfaces are completely flat against each other and that the wires is still laying in the slots. It’s a good idea to use a clamp or two to really squeeze the two pieces together to ensure a really tight fit, it becomes much stronger that way. Have a paper towel or something close by in case glue comes squirting out.
I personally use 60/40 0.8mm thich lead based solder. I highly recommend using lead/tin based solder instead of the lead-free kind. It’s a lot easier to get a good result with and it’s actually less harmful to breath in the fumes.
Snaking the wires through the booms is a lot easier if you take out the servo wires out of the servo connector. Simply lift the little tab with something thin like an exacto blade and pull the wire out.
Put on some heatshrink and then solder the motor wires in place.
I’m using a 1.3Ghz video link and I needed to build an antenna. I was lazy so I grabbed this 5.8Ghz antenna with a broken case and turned into a 1.3Ghz antenna. (Here is a guide)
Antenna done. Going to put some paint on it.
I absolutely love how this Tricopter flies. With the new TriFlight firmware it’s locked in and smooth. The new motors work flawlessly and have tons of power. My favorite FPV platform of all time. It just doesn’t get old. Just remember to balance your props before you fly!
