The assembly of all components was pretty straight forward (only one spring was bent so one of the landing legs vibrated very hard while the motors were running, solution was to just cut a couple windings off).
There is no manual to the X666 Frame, but it's building is similar to the X525 so just look at Hobbyking's files page to the X525 or use this link! It's really simple to build!
Mounting Motors:
Here are the three things you need to do:
- As I was trying to put the screws and locknuts at the right position and fasten it while the landing gear is mounted I gave up very quickly... It's just not possible, you have to remove the holding screws and these stupid easy bending springs 4 times...
- Of course the motor cannot just be mounted as is, you first need to remove the base from the brushless motor. This is done by a small setscrew that has some strange sort of head. The inbus (or Allen) bits where either to big to fit or to small so it spin the screw. The great solution was to hold the bit angular to the screw axis. This way I was able to remove these damn screws.
- These screws tend to vibrate themselves out so the motor will just fall out of its base. Here's the thing I learned that is essential to safely build a quad:
Threadlocker such as Loctite 243 or else
I didn't bought the ultra strong Loctite because to remove the screws you need to apply heat.
Applying this is very simple, better take too much than to little. Too much won't hurt your quad, too little may result in a bad crash.
All the other stuff:
For my first Setup I needed to upload the latest OpenSource Firmware to the Control Board. This is actually a pretty easy Task. You only need an USB-ISP Interpreter (cheap ones from EBay work just fine) or an Arduino which can programmed to act like one! I already had an Atmel AVrisp mkII from former microcontroller projects so I just used this one.
You then just need to insert the ISP Header on to the Board! Now here the fun begins...
I did search for nearly an hour to find out where Pin1 is situated so I wouldn't connect the interpreter wrong and maybe even cause damage to it... At the end I just looked very closely to the board Layout, then looked on the ATmegaP328 Datasheet which pin is Miso and Mosi so I finally could figure out that pin one is up right if you look at the board full front (so you can read the infos on it)!
For the actual programming I just followed the great tutorial given by Flitetest, which is one of the nicest RC Channels on youtube!!! link
Next thing was to solder all the 3.5 gold connectors to the motor cable and fix it with the Controller Board with Velcro. I saw someone on youtube suggesting to left the Controller Board within its foambox to prevent vibrations causing problems to the Gyros so I taped Velcro directly onto the foambox.
Last thing was to mount the colet type Spinners including props onto the Brushless motor shafts.
That was it! Actually pretty easy if you have all the necessary parts ^^
I only had to wire all the inputs of my receiver to the inputs of the Controller Board and voilà :)
Here's a pic of the version 1.0 of my quadcopter :
Now its time to wait for better weather (at least no rain) and then try it out :D
