In this article I will show you how I built my new FPV quad and a video with the first results.
We start right of with the first video.100% pure and honest quadcopter footage: no auto level,no gimbal and no post stabilization.
And here is how I built it:
Warthox designed a new FPV quad frame. Perfect chance for me to send my two year old FPV quad into retirement and build a new one based on warthox' new FQuad frame.
The frame is meant to be a light, simple but durable platform. So I will also only use a simple FPV setup: only one camera (GoPro), no GPS and no OSD. Only the following equipment will be used:
Flyduino 30A ESCs
Tiger Motor MT2208 1100kV
GoPro Hero 1
Foxtech 5.8 VTx
CL antenna by chipsundgrips
FRSky FASST compatible 2.4GHz diversity Rx
First step was to solder the needed pins to the NanoWii board, upload the software, establish the RC link and programm the radio. As the ESCs I chose do not have a BEC I use the one integrated in the NanoWii (two pins on the right).
I planned to have the motor wires on the inner sides of the frame. So I needed to mount the motors with wires on the left on two arms and on the right on the other two arms.
The ESCs have a special multirotor firmware (similar to simonK) and come just as the boards without wires or capacitors soldered to them. So I had to solder them first.
To save weight I didn't want to use connectors between the ESCs and the motors. Instead I soldered the motor wires directly to the ESC boards. Because you can't change rotation direction after heat shrinking the ESCs I needed to check the rotation direction on each ESC.
Now the ESCs and battery connectors were soldered to the bottom plate of the frame. As you can see I like to use 4mm bullets on most of my RC stuff.
The two black and white cables on the right will feed the 3S lipo voltage directly to the Vtx and the NanoWii.
Allright, time to put everything together and do a test hover.
Without the FPV gear and battery the quad weighs 535g, ready for maiden.
Maiden went just fine, so I put the FPV gear on it.
I'm really pleased with the frame and my new quad. Looks good and flies great.
