Looking to build the smallest GoPro host possible
RD22 and RD23 Added to the fleet
Introducing RD22 & RD23 a pair of twins. This little babys are based on the Quadrixette Nano Airframe and the CopterControl by OpenPilot.
The idea being that we wish to build the smallest possible AP/AV/FPV platform for portability. Technically, I should be abe to fit a radio, a spares kit , lipos and the model iteslf along with a gopro into a single case.
The Nano is made from aluminum and fiberglass. For the initial attempt I will use Hobbyking Plush 6A ESCs to control A1510 2200KV Outrunner Brushless Motors, spinning some form of 3 blade glass fiber prop.
RD23 - Buzz - The Build Begins
We start this session laying out all the components. We have used the Quadrixette Nano frame from eyefly.info and the landing gear from an align trex 250. The motors are A1510 2200KV and the ESCs are from hobbyking - Turnigy Plush 6a.
Then we mark the aluminum arms for driling
Then we drill them,
I used 1/8 for the bolt holes, 5/32 for the motor shaft, and 3/16 for under motor mount holes.
Then we attach the arms
and the landing gear struts
Frame is built here
rear motors go on
All motors are mounted
ready to solder
solder mini 3pin plugs on the ESCs
Ready to heatshrink
Complete
Warning, do not, repeat: DO NOT cut down the wires on these motors, they are made of a strange wire with odd insulation, if you do, it is almost impossible to retin the wires and make the solder stick, I learned my lesson after it took me 1hour to solder the plug onto the motor, I left the other 3 at full length. In this shot I have cut them very short thinking ti would be easy to tin them.it was 99% impossible.
Soldering the full length ones was easy in comparison
All motors soldered
Calibrating throttle on the ESCs and testing each for full operation.
one DSM2 4ch rx and 4 ESCs ready for mounting
This is the curent state of the model as we wait for jan 3 for the post office to open soI can collect the flight controller for this model.
RD23 - Buzz takes flight.
The final build session begins with the arrival of the flight controller. An OpenPilot CopterControl board purchased from flitelab.com the Canadian distributor for the OpenPilot project.
We start by unpacking the CopterControl board aka the CC Board.
we mount it on the Nano on the nylon standoffs.
side view - installed
Next we add standoffs, these will act as supports for the head protector later.
Now we add a 6ch RX (CC likes 6+channels) and recalibrate the ESCs then we modify 3 of the 4 ESC cables to disable the +v to the CC, we only want one ESC powering the CC. you can see the white shrinktube where the mod has been made on each of the 3 ESCs.
Now to shrink the ESC->FC plugs
Here I have zip tied the ESCs to the arms, and fed all power wires to the main body and routed all ESC plugs to the flight controller
Here I have routed the RX cables and mounted the RX with velcro.
Ready for props
Props go on.

AUW 289 grams with 1200 mAh lipo
Just for an intial proof of flight test, I attached a hyperion 2100 mAh lipo (weighs in at 130 grams) and literally flew around the house in 3 different modes for 16 minutes and 16 seconds. The real inteded batery is a turnigy nano 1300 (76 grams) wich I hope gives similar flight times.
Video coming soon.
RD23 aka "Buzz" gets a new home and Owner
This model was built for my bro Bam, and last night I delivered it and he got a chance to fly it around the jam room. I managed to get a picture of him holding his new Nano :)
