Like many drone fans, my first diy best quadcopter build used the kk2.X flight manage board. I went through several iterations of my kk2 quadcopter and i nevertheless noticeably endorse the kk2 for beginners and everybody looking for an low cost, capable flight manipulate board. It’s were given assist for just about any multirotor configuration you can consider and the automobile-stage characteristic is stable, particularly with up to date firmware. However, i wanted to attempt out a extra superior flight manage board due to the fact i have a sturdy interest in self sufficient flight and wanted as a way to program waypoints and missions. After doing a ton of studies about the various autopilot flight manage forums obtainable, i determined at the apm and extra mainly, the apm clone arduflyer from rctimer. Equal to the 3drobotics apm and available at a decrease fee factor, the arduflyer boasts talents similar to a few different flight controllers that price actually lots of greenbacks extra. Along side the arduflyer, i could be using the rctimer 915mhz telemetry package and the u-blox cn-06 gps receiver v2.0.

Preparing the ArduFlyer Board

The cables that come with the gps and the telemetry air module can be set apart; they don’t suit the arduflyer, which comes trendy with cables for connecting the gps and telemetry. Additionally included with the arduflyer is a packet of headers. One downside of the arduflyer in comparison to the 3drobotics apm is which you ought to solder the headers at the board your self. That’s step one i took to get this project going. I chose to use the straight headers instead of the ninety degree ‘aspect-access’ set. One of the units of eight headers goes at the “inputs” phase at one stop of the board and one goes on the “outputs” section at the other quit. The long set goes on the facet in which the usb plug is. You can optionally take away the closing rows of 3 pins on the long set of headers as shown within the photo underneath. Use a pointy application or exacto knife to cautiously cut the plastic. If you plan on powering the arduflyer the use of the built in bec for your pace controllers, be sure to solder the two pin header into the holes categorised jp1. That’s what i’ll be doing first of all. Afterward i’ll upload a ubec or 3dr power module.

Mounting the ArduFlyer to the Frame

As soon as all the headers have been soldered onto my arduflyer, the subsequent step become to clean off some area on my flamewheel f450 body. I removed the kk2.Zero board, the receiver, and the velcro preserving them both down. I wiped clean the surface well so i would be able to connect the brand new board securely. I also eliminated the propellers, due to the fact i’ll need to calibrate my radio and escs later on and don’t want to danger losing a finger.

Using more than one strips of froth double-sided tape, i set up the arduflyer inside the exact middle of the frame, being cautious to orient it so that the “the front” arrow at the board pointed closer to the front of my quad. In this case the white fingers on the frame are within the the front.

Connecting the ESCs to the ArduFlyer

Once the board is secured at the body, the following step is to attach the escs. Coming from quadcopter a kk2.0, you’ll be aware that the motor numbering is extraordinary with the arduflyer. The esc cables plug into the “outputs” phase at the back of the board. For an x configuration quadcopter, the top right motor is #1, the bottom left motor is #2, the pinnacle left motor is #three, and the lowest right motor is #4. Right here’s a handy diagram showing the motor number layout as well as the course of rotation and the sort of propeller every motor need to use.

Installing the GPS and Telemetry Radio

Subsequent, i connected the gps and telemetry air module to the body and plugged the cables into the best locations on the arduflyer board. I secured both with double sided foam tape, and delivered a couple of small zipties to the gps unit as nicely. Be aware the placement of the telemetry air module. Make sure now not to dam any connectors at the arduflyer board.

Turnigy 9x Receiver Installation

Next i brought the turnigy 9x receiver, held to the body with a strip of industrial power velcro, and connected the wires to the arduflyer. The receiver wires connect to the header at the front of the arduflyer board categorised “inputs” and start with #1, which is the furthest far from the threshold of the board with the usb port. For the turnigy 9x, the receiver need to be connected as follows. You may get flying with just channels 1-4, but you’ll want the potential to set up a few different flight modes to take full benefit of the arduflyer.

Channel 1 – Input 1
Channel 2 – Input 2
Channel 3 – Input 3
Channel 4 – Input 4
Channel 6 – Input 5
Channel 7 – Input 6
Channel 8 – Input 7

The channel 1 – input 1 connection should be made using a 3 twine servo lead. On the receiver, the black or brown twine is going in the direction of the lowest of the receiver and on the outer edge of the arduflyer board. The rest of the channels can be connected the use of single jumper wires, because handiest one of the pins for every channel desires to be connected. Some other option is to use wellknown three twine servo leads and remove of the wires. For all channels except channel 1, join the top pin on the receiver with the innermost pin on the arduflyer.
