Whoover build (3 min 55 sec)

I made a whoover from an old black h8 frame
It has 6mm motors
720 lift motor mounted on a walkera ladybird leg mount
It runs on an unused jjrc1000 FC but NotFastEnuff has great firmware for blueboard and Bwhoop FC's

I used 3 1000uF caps on the motors to filter gyro jerk

It has the AKK BS2 AIO FPV camera mounted on the frond of the H8 mini frame with a rubber band and some metal spike pushed through the frame

The skirt design with a sandwich bag works very wel the skirt blows up and passess air to the front. When you speed up more weight gets on the nose of the craft and the RPM of the lift motor goes down making it whoover very nicely.
Not much firmware in this project but NotFastEnuff has some ready!

Do you have problems with legal limits to your fpv transmitter?

Is the police checking transmitter power in your area?

Switch power at the push of a button!

The TX526 by Eachine transmits a very clear image from 18mw to 932mw.

TX 526 review video (3 min 55 sec)

As you can see It is a real powerhouse but can also go under the radar for racing or to comply with legal limits.

It remembers your settings and all the settings can be easily accessed with simply one button.

I have flown with this transmitter over 30 times without problems.

Here is my review

Get it here at Banggood:

Custom pid settings that reduce prop wash and improve the handling of the quadcopter.
Your flight will be much smoother.

Hello guys in this article:
Iíve shown you guys how to build the X210.

my X210 is capable of Dshot.

What is Dshot?

Dshot is a new Digital protocal for communication between your flight controler and your ESCís
Where old PPM signals consisted of short and longer pulses, this code changes that in to bits and bytes.
This has a several improvements:
You donít have to calibrate the escís in BL heli or betaflight, you just set min and max to 1000 and 2000us
You donít have to set minimum throttle because this will be calculated and spin your props at the absoluut minimum speed when you arm possible.
There is less jitter and stutter caused by interference because bits and bytes (zero and ones) cannot be easily changed by changing magnetic fields caused by alternating current produced by the motors.
The update frequency can be improved in 10fold from what iíve read and so far understand.


Trying Dshot (4 min 59 sec)

I installed Dshot on my SP racing F3 from the latest commit of Boris B
I also downloaded the latest BL heli 16.42 (experimental Dshot) Hex for my Racerstar 30A escís
Download and find silabs and then Dshot testcode hex files.

DIY 90.000 MAH Lithium ION Battery! (8 min 36 sec)

step 1 get 30 dead or old stock laptop batteries
step 2 Take the batteries appart and split them into single cells.
You should have about 100 cells from dead laptops to make a 40 battery high capacity high quality field charging battery.
step 3 Charge all the cells individually
Step 4 Discharge all the cells individually and write down the amount of power they provided on the discharge cycle
Step 5 Charge all the cells and weight a month to see whether the batteries have a short and drained down to 0 volts again. Throw bad batteries that are dead or that have very low capacity away. this should be around 20%-40%
Step 5 Design your battery
Step 6 Build your battery with the proper hardware.

Parts required:
Silicone wire:
Ebay old batteries:
Soldering Iron
18650 charger chips USB:
Balance wire
Solder tabs!
Xt60 connector
ABS Battery holder:
Heat resistant tape to put on the contacts

I've been actively building brushed quads for a year now and brushless Silverxxx, Domsen quads for 0.5 year. My next thing would have to be a quad capable of carrying a camera.

Problems that needed solving:
Transmitter and receiver combo?
Frame ESC and Flight controller?

Goebish worked this summer on the AFHDS2A protocol that is used with turnigy and flysky transmitters.
It uses the A7105 module for my Devo7E. There is allot of receivers made by flysky and turnigy that are bulky. I went for the TGY-iA6C

A cheap but well put together kit is the Realacc X210 with 2300KV motors. for 100 euro you get props, motors, esc's and a nice frame that can carry a gopro.

Everything is build now its time for my first flight!
Realacc X210 First Flight (3 min 29 sec)

I had problems with range. My range was only 50M

After I rewired my A7105 module and build an awesome handcrafted 2.4ghz dipole antenna from some Coax.
I seem to have zero range issues for at least a couple 100 feet!
I used the old wiring for my A7105 chip, and I can recommend everyone to change this to the new wiring as I believe this enables the power amplifier that is build into most DIY A7105 chips.

I have two youtube video's on my youtube video that show, that with the old wiring I had 50M range at most, and with my new wiring Im not noticing any issues as you can tell from the footage.
I've also installed a 1000uF 6V capacitor on the + and - of the chip I believe this might help a tiny bit.

I've build a...Continue Reading

Silverdomsen Quad 3D "4S punches" (0 min 22 sec)

H101 Floureon
4 resistors 1000 ohm
4*Dys XM 20A esc
4* Emax 1306 4000KV motors
Diatone mini 2A BEC
Silicon wire 18Gauge
Female XT60
Lantian LT130 frame
rubycon 220uF 35V cap
2*CW & 2*CCW HQ 3*3*3 props (are very well capable of 3D)
BoltHV 850MAH 4S battery (cheap on hobbyking and worth for the money)

Step 1: gut floureon and install easy flash pins with superglue and solder.

Step 2: Install motors and ESC's keep wiring short or use wrap around technique. Solder both front ESC red wires together, Fold a piece of 18gauge wire and leave 4cm. Strip insulation from the fold and solder the red ESC wire to the bigger wire by inserting it in the wire core. Do the same for the black wires.
4CM side of the 18gauge wil go to the diatone BEC underneath H101 FC also install capacitor here. and the other end to the battery and the other ESC's. Run the BEC under the H101 PCB (wrap it in one layer of Etape)

Step 3: Install resistors on the ends of the motor contact pads. Remove the small brown capacitors in parallel with the motors on the FC Arms. Drill small 1MM holes in Lantian plastic board standoffs and mount Floureon board with Floureon Bodywork screws to standoffs.
(drilling holes in the plastic standoffs avoids having to drill holes into the H101 PCB, it also creates space for the Diatone mini 2A bec to fit underneath the H101 PCB as it is now mounted higher, use a soldering iron to make...Continue Reading
