Within the first submit on this series, i went via all of the elements i ordered to assemble my best quadcopter. The whole thing has arrived and now it’s time to get busy building! The first step is to bring together most of the frame so you have someplace to attach the rest of the components. The primary standards of a quadcopter frame are the identical even though yours is a distinct model. You need four palms to hold cars, propellers and pace controllers; middle plate(s) to preserve the battery, flight controller, and receiver; and touchdown tools or skids to guide the quadcopter and take the brunt of the effect on any difficult landings.
Update: the wooden hobbyking body i initially purchased turned out to be genuinely shoddy and susceptible. One of the arms broke irreparably on certainly one of my first flights. After numerous iterations of diy quadcopter frames, i were given a dji flame wheel f450 frame that’s long lasting and low priced. The build outlined on this put up is glaringly based at the hobbyking body, however the general steps are nevertheless the same as a ways because the non-body additives go.
Step one for my frame is to connect the 4 palms to the large center plate and cozy them with nylon nuts & bolts. I used a little bit of superglue on every joint as properly for delivered balance.
Subsequent i set up 4 long nylon screws pointing up at the top of the massive center plate. That is wherein the flight control board will go.
Then, i positioned the 4 huge nylon spacers on the smaller middle plate. This may create the inner area wherein the battery will rest.
Here’s my frame once I positioned the kk2.Zero flight manipulate board at the 4 mounting bolts and popped the small center plate into role under the large center plate. Ensure all the notches in the timber line up so that you have a tight fit and all 4 of the nylon bolts connected to the lower (small) middle plate are sticking up via the bigger plate so that you can attach bolts to hold the whole lot together. I tried the usage of the touchdown gear that came with this frame, however it’s miles extremely flimsy and mine become lacking components needed to bring together it, so i ended up constructing my own landing tools and getting rid of the protected one.
Next step is to attach the cars to the ends of the palms. My frame’s hands got here pre-drilled for several exceptional motor sizes so it was easy to connect the vehicles. It’s actually starting to look like a quadcopter now!
The following few steps contain soldering connectors on the escs to attach them to the motors and making a wiring harness to attach the entirety to the battery. It’s far feasible to store time by means of shopping for escs that come pre-stressed out with connectors but the ones i wanted have been backordered and i’ve a variety of experience soldering so i didn’t mind having to wire the whole thing up myself. You may sincerely need to apply a heatsink on every occasion you’re soldering whatever to an esc because they may be damaged through an excessive amount of warmth. I purchased a number of those three cord bullet connectors for connecting my escs to my vehicles to maintain the whole lot tidy. A small clamp to hold the connectors even as you solder the wires to them comes in very available.
The next step is to wire up the escs in order to hook up with the battery. To try this i connected two escs to an xt60 connector, then connected the other end of these xt60 connectors to a third xt60 connector which i soldered on to my battery leads. It isn’t quite but it’ll get the job achieved.
Admittedly, i need to have gotten a energy distribution board which is basically a tiny board with a wiring harness constructed into it. My diy wiring harness changed into unpleasant and heavy so no longer perfect for a quadcopter, where weight is a essential factor. I’ll be ordering a electricity distribution board soon and a good way to be one in every of my first enhancements. Udate: i recently got a dji flame wheel f450 quadcopter body, which has a constructed in power distribution board and enabled me to remove this unpleasant homemade wiring harness. See my flame wheel f450 overview.
I connected the escs to the hands of the quadcopter with zipties and ran my unsightly diy wiring harness along the sides of the kk2.0 flight manipulate board. The motor wires may be attached to the esc connectors along the underside of the arms.
Next i attached my receiver to the middle plate in front of the flight control board and connected all the wires. If you’re the use of a kk2.0 flight manipulate board the escs ought to be plugged into the slots along the right facet of the board (if you examine it with the buttons on the lowest). The black or brown cord from your escs is the floor and they should be plugged in with the floor toward the edge of the flight manage board. If you’re the use of the quad x configuration, then the pinnacle-left motor is #1, the top-right motor is #2, the lowest-right motor is #three, and the bottom-left motor is #four. The slots at the left side of the board are for radio channels and must be connected in your receiver, again with black or brown wires facing out. For this manipulate board, handiest one of the slots desires the power wires connected (pink and black/brown) so i eliminated them from my male-to-male servo leads for the alternative three channels. I later secured the receiver to the board with a touch double sided tape.
The last element to attend to from a hardware standpoint is the landing gear. Those protected with my frame were in reality susceptible so i stopped up casting off them and building my personal out of a 1″ huge aluminum strip i got at lowe’s. I used a dremel to cut equal lengths, 16″ every.
To shape the touchdown equipment legs i measured six inches from each end and bent the aluminum over the the front edge of a chair. Extremely excessive tech fabrication process right here.
