Building a 280mm Quadcopter out of spare parts (Motors and ESCs)

Part I – The Frame

While waiting for more spare parts to arrive (batteries, some adhesives, a PPM/PWM converter and some connector cables), it was the perfect time to install the motors and ESCs to the frame. If you have not read the first part of the build log, I used the EMAX Nighthawk 2204/2300kV motors and EMAX BLHeli 12A ESCs.

The Eachine H8c is an affordable toy-grade quadcopter featuring a gyroscope stabilization system on 3-axis (6-axis as manufacturers like to advertise), that comes in a complete Ready-To-Fly (RTF) package. Inside the quadcopter canopy, there is an HD camera (with microphone) that is capable of video and picture recording (the camera can take pictures while recording video). The H8c is available on two colours, white and black, with the black version having a “mean” look while the white one is more suited for night flying. The review model was the black version.

Building a 280mm Quadcopter out of spare parts (Frame)

This is a project that aims to build a 280mm quadcopter with racing/cruising characteristics completely from spare parts. The idea came to mind after Banggood sent me by accident a broken/used Flying3D instead of my paid order (they sent me later my brand new unit); the broken unit had burnt ESCs, the power distribution board was severely damaged, even the flight controller board was not responding. I can only assume that the previous owner (there was printed e-mail exchange between Banggood and the U.S customer inside the box) tried to mod the quadcopter unsuccessfully and then returned it to Banggood as defective. My God, what people are out there!

Mounting a RunCam2 HD on a Flying3D X6

Recently a RunCam2 HD arrived at my door. You can read a detailed review here, together with a comparison test against Mobius C2 and Xiaomi Yi. The most obvious thing to do was to mount it on my 230mm quadcopter, the Flying3D X6.

• Built-in WiFi 802.11n circuit for trouble-free and fast connection.
  
• Removable 850mAh, 37V battery.
  
• Improved 120-degree FOV lens with extra protection cap.
  
• Brand-new and user friendly Android and iOS apps.
  
• Improved (even more) RF-shielding using internal metal casing.
  
• Enhanced image stabilization capabilities utilizing a built-in G-sensor.
  
• Full FPV capabilities (powering the camera from any 5V-17V source, OSD menu).
  
• … and many more.

YiZhan/JJRC Tarantula X6 TX diversity mod

The YiZhan/JJRC Tarantula X6 quadcopter RX/TX uses the WLtoys v2x2 protocol which is known to have good range. This was the case with the original YiZhan Tarantula X6 (no longer commercially available) where the range was excellent (up to 300 meters in many cases). Unfortunately, the later/current builds do not have the great range of the original, in most cases is no more than 150 meters. To make things even worse, there are reported signal drop-outs and laggy behaviour when the quadcopter is over 60-70 meters from the transmitter.

YiZhan/JJRC Tarantula X6 v686g FPV camera mod

The YiZhan/JJRC Tarantula X6 is an affordable brushed quadcopter suitable for fun flying. The quadcopter has a camera port but the stock camera (comes in two versions, 2MP and 5MP both non-FPV capable) leaves a lot to be desired. As I already had the JJRC v686g quadcopter, the possibility to use it’s 2MP FPV camera with the Tarantula came in mind.
