+ | This is how electricity from the battery gets to all of the components that need it. Solder the ESC's, camera power connector, and battery connector to the correct places. If you want anything else that needs power on the quad this is where you would connect it as well. Here are some pointers before you begin: | ||
*Make sure that you are soldering the right wire to the spot. Each point is labeled with a + or - sign that indicates whether its a power or ground point. If it is not printed on the board look up the schematics of the board. Please do not mix them up as if can cause component failure (i.e. explosions and fires) if the polarity is backwards. | *Make sure that you are soldering the right wire to the spot.

*Be careful of what you connect to it. The power distribution board will distribute the voltage equally among all of the components. Thus if your esc, camera, or any other items are not rated for the amount of voltage coming from the battery they could get damaged. If you need to connect an item that takes a lower or higher voltage than the battery you can use a voltage regulator like this [[https:// | *Be careful of what you connect to it.

This meant that there was no power going to the FCB. After reading this [[http:// | + | While soldering the ESC's we noticed that the flight controller board (FCB) connector only had two lines.

+ | Usually I would want to mount the FCB above the PDB using mores spacers. However Because we failed to take off the cover that came with it (the pale yellow box) we decided to use double sided tape and stick it to the underside | ||
+ | \\ | ||
+ | |||
+ | {{: | ||
+ | |||
+ | ==ESCs== | ||
+ | \\ | ||
+ | Since these are soldered to the PDB there isn't a lot of play on where you can place the ESCs. Especially on the small frame of the 250. Depending on your frame the best place for the esc can differ but in our case we stuck them down, using double sided tape, on top of the arm they were closest to so that there was one ESC per arm. You can also use zip-ties or electric tape to do this. Then take the 3 pin connector and connect it back to the FCB. Please check the manual for your FCB because where you plug the ESCs in is different for each. For the cc3d it was from the top pins Front Left, Front Right, Back Right, Back Left, with ground on the right and signal on the left pin. Then the power pins we created went into one of the open pin slot with power in the middle and ground on the right. For now don't worry about the loose motor connectors, we will secure those down later. | ||
+ | \\ | ||
+ | |||
+ | ==Motors== | ||
+ | \\ | ||
+ | The box that the motors came in should have also came with some screws, and maybe an allen-key. Don't lose these screws since you will be using them to screw the motor onto the frame. If they didn't come with an allen-key first find the correct allen-key to screw them in. Then check the mounting on the bottom of the motor, | ||
+ | A tip I would give is to check which direction the propeller nut goes onto the motor. It will either go on cw or ccw. Reference an image of what direction the motors need to go (this is different depending on the frame type or number of motors) and mount the motors so that the direction the nuts goes on is the same direction the motor spins. This is to prevent | ||

+ | \\ | ||
+ | Now if you want to you can put the top of the frame back on. But make sure the the usb mini port on the FCB is still accessible. You will be using that port in the next step. | ||
+ | \\ | ||
- | ===FPV Setup=== | ||
- | Setting up the FPV is simple; however it is important to double check what voltage each component is rated at in your system\\ | ||
- | The main components are the camera and transmitter, | ||
- | \\ **1.** Solder the transmitter power cable to the power distribution board.\\ | ||
- | \\ **2.** Mount the camera to the frame.\\ | ||
- | \\ **3.** Connect the camera to the transmitter.\\ | ||
- | \\ **4.** Mount the Transmitter to the frame.\\ | ||
- | \\ That is all that is needed to set up the FPV on the drone. The Next step is to get the headset you will use to fly the multirotor.\\ | ||
====GCS Setup==== | ====GCS Setup==== | ||
- | \\ Once all of the components are on the frame of the quad you will need to find the usb port on the flight controller board and find the appropriate cable to connect it to a computuer with a ground-control-station (GCS) program on it. **Make sure that your flight controller board is supported by the GCS program before connecting it.** \\ | + | \\ |
- | \\ Once you have the appropriate cable and GCS program connect your quad (with the battery unplugged) to the computer and start their vehicle setup wizard. Follow their instructions closely and read each instruction carefully. \\ | + | Congratulations, |
- | \\ After your done with that go onto the controller setup wizard. If you have any problems with the controller not registering on the computer, re-bind the controller to the receiver (if you don't know what that is google it), double check the connection between the receiver and the flight controller board. The connecting pins might be bent. Also try closing the program and opening it up again (i.e. turn it off then on again). | + | |
- | \\ One thing you should be careful about during the controller setup wizard is the arming sequence. This is the sequence you have to follow to allow the motors to run. So after turning on the controller, then the quad on you have to follow this sequence before being able to fly. \\ | + | |
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | | ||
+ | At this point you will need to either find a computer with a Ground Control Station (GCS) software on it or download one. The one we used is Open Pilot GCS. Unfourtunately this GCS is no longer supported and is not available for download online. I would suggest that you use [[http:// | ||
+ | Before downloading any GCS software please check which boards the software supports. Sometimes an earlier version supported a board, but the newest version dropped supports. I had this issue with my cc3d and Open Pilot where I had to download an older version that supported the board. | ||
+ | Follow the vehicle setup wizard to configure your quadcopter. Then after your done go onto the controller setup wizard. | ||
- | ===DONE!!=== | + | Now it is time to tie/tape down all of the loose wires on the quadcopter down. Use what ever method |
- | \\ Once you have gone through | + | |
- | \\ **Now go out and crash it!!!** \\ | + | |
- | ===Test Flight | + | Before putting propellers onto the motors and flying it is important to know that propellers have cw and ccw directions as well. You will want the high end of the prop to move around scooping up air and pushing it down. This lets you know whether it is cw or ccw. Put the cw propellers on the cw motors and ccw propellers on the ccw motors. |
- | Drone 1 | + | Secure the battery to the frame using double sided tape or velcro zip-ties, and done! |
+ | |||
+ | Now it is time to take the quadcopter for a test flight! | ||
+ | Tip: Be vary, vary, vary easy on the throttle. The last thing you want is to explain why there is a hole in the ceiling. | ||
{{youtube> | {{youtube> | ||
- | Drone 2 | + | ====FPV Setup==== |
+ | \\ | ||
+ | Now that you have finished the quadcopter aspect you have to create the FPV setup to create an FPV quadcopter! | ||
- | {{youtube> | + | These are the items you will need for this part: |
- | | + | |
+ | *The quadcopter you just finished | ||
+ | *A video camera | ||
+ | *A video transmitter | ||
+ | *The corresponding wires to connect the camera to the transmitter to a battery | ||
+ | *A video reciever (inside the FPV goggles) | ||
+ | *A video monitor (the FPV goggles) | ||
+ | |||
+ | If you bought the bundle set I put as the link you will not have any issues with compatibly however if you buy the items separately this won't be as easy. | ||
+ | |||
+ | *1) Figure out how you will power the transmitter and the camera. The set that I linked earlier comes with a battery. However there are pros and cons to this. It is great if you want to keep the FPV setup independent of the quadcopter setup. This might be usefeul if your quadcopter runs out of battery and you lost physical sight of it. You can use the FPV camera to locate it by seeing what is close to the quadcopter. However this adds extra weight and is another point of failure. Extra weight can cut flight time and if the FPV battery dies out midf-light and your don't have a physical visual of the quadcopter you are flying blind. For a first time setup I would recomend using the battery since it is much easier and quicker to do. But after maybe 1 or 2 flights to switch over to using the PDB (remember the JST connector we soldered?) to power it. | ||
+ | *2) What you do next will depend on what you decided. | ||
+ | *If you decided to use the battery connect everything on a table and test the equipment. Toggle the channel finder to get the video feed and check that everything is working. <fc red> Do not turn on the goggle or video transmitter without connecting the antennas to them first. They will explode if you don't </ | ||
+ | *If you decided to power them from the PDB find out how you will power them. | ||
+ | *Some video transmitters have a v-out out to the camera while others don't. If it does check to see that the voltage coming out of the transmitter is what the camera can handle. If it isn't either buy a voltage regulator or another camera/ | ||
+ | *If the transmitter doesn' | ||
+ | *3) Now all that is left is to put it on the quadcopter. Find a spot on the front end of the frame to mount or secure the camera to. Use zipties, electric tape or double sided tape to do this. Then find other places to put the rest of your setup so that it isn't interfering with the rest of the setup. | ||
+ | *4) Time to fly using FPV! Be vary cautious and double check your surroundings first. | ||
