hit a 100' tall tree the other day and the quad, broken props, everything but the gopro 4 was right at the base. even the small piece of foam i use to pad the gopro 4 was at the base.

looked for days as it was pretty thick woods with lots of downed material around but never found the gp4.

now going to try this tile that is Bluetooth and has a 100' range on a tablet or phone.

after using the tangle of wires to feed the vtx and cam from 14v through a ubec i am now trying the RROSD PRO MINI PDB which seems to working great, not buggy yet. i am just using it to power my vtx and cam, the power from the pdb, 14v, is feed into the RROSD PRO MINI PDB and then the cam and vtx are powered off the RROSD PRO MINI PDB with voltage on the osd. the osd also has mah and rssi but the mah will not display unless you run the esc's though the board. have not tried rssi yet. did try the osdoge and powerosd pro but both seem buggy and sometimes the display would not work.

as you can see there was a tangle of wires and special soldering required to install the ubec, with the RROSD PRO MINI PDB it is all plug and play

the green led is solid when powered but no vtx or cam and blinks when vtx and cam are working

Not sure what happened, looks like a esc/motor/motor wire/loose prop failure?

My quick reference for setting up Beatflight, Naze32, Futaba 8fg, EZUHF

Futba 8fg;
reverse elevator and throttle

Board Alignment USB on left side;
90 Yaw REV5
180 Yaw REV6

Receiver Mode;

ESC/Motor Features
1150 min throttle
1520 mid throttle (futaba)
2000 max throttle
1000 min command

Profile 1; Multiwii rewrite
Profile2 ; Luxfloat

roll and pitch rate; 25
yaw rate; 20

throttle expo; 0
rc rate;1
rc expo; 30

Jittery points in Receiver Tab; in cli:
set deadband=6
set yaw_deadband=6
works good on my futaba 8fg

Naze32 REV6
Checkbox in Config

Failsafe with Cleanflight, Beatflight, Naze32, Futba 8fg, EZUHF;
Hold the futaba stick in the disarm position while setting the Ezuhf failsafe.
set failsafe_delay = 10

To get 2KZ going, so far i have learned that you have to disable:
Naze32 REV 6B
set gyro_lpf = 188HZ
set acc_hardware = 0
set baro_hardware = 0
set mag_hardware = 0

to get 2kz in cli:
set gyro_lpf = OFF
set acc_hardware = 1
set baro_hardware = 1
set mag_hardware = 1
now go back to config, bottom left you will "cycle Time:" before it was around 1000 it should now read somewhere around 500

for info in cli

qav400 - naze32 - 4s 3600mah - rotorgeeks 30a escs -1200kv motors - betaflight - oneshot - dampening light - gopro4 4k video

post crash analysis:
its hard to really say what caused this failure. i do remember the screen going to snow and i may have cut the throttle out of habit. it all happened so fast as it was in a 50mph dive and the next second it was on the beach.

upon post power up all systems worked perfect except esc1 which powers the naze32 was not working. the others are opto. upon further power ups esc1 reactivated and works normal, have had this problem a couple of times but if i reboot it comes back. this qav400 pdb could also be suspect as it had reverse polarity burn out on battery 1 connector. i moved the battery connection to battery 2 and and continuity showed good on all connections.

the battery was ejected so now way to tell if that became disconnected but highly unlikely, xt60 connectors. the rx wire was disconnected, probably caused by crash as it is zip tied in several spots to prevent disconnect. the vtx was loose but not out and still had signal. antenna came apart at the 90 degree to the vtx, could have come off in flight? but is secured by rubber bands.

it could have lost power from esc1 to the naze32 and gone into failsafe, 0 throttle, but the vtx system is powered by a good quality bec off the pdb. why did the video signal go out?

so who knows? really no damage except one broken landing gear, really amazing considering the impact.

i am going to tear it all down and move the esc's to a good pdb. but i first i must go fly!
QAV400 - NAZE32 bad crash, total power loss? (3 min 33 sec)

so i messed up my solder job on my Seriously Dodo Flight Controller on the motor connectors as to where motor 1 and motor 4 do not work as they are getting no signal.

in cleanflight you can reassign motors to different channels in cli.

cleanflight 1.10 and betaflight 10/15 release fw, note cf 1.10 uses mmix instead of cmix

# mmix ////will show you current motor setup, probably quadx, take note of settings to reassign them.

# mmix reset ///clears the current settings

# mixer custom ///enters you into the programming

now to enter motors, you have to start at 0 and go in order.

since the pad on motor one was messed up i entered this which disables that channel, note that 0 is really motor 1
#mmix 0 1 0 0 0 0

this reassigns motor 1 to channel 2 on the dodo
mmix 1 1 -1 1 -1

this reassigns motor 2 to channel 3 on the dodo
mmix 2 1 -1 -1 1

enter mmix and it should now look like this
# mmix
Motor Thr Roll Pitch Yaw
#0: 1.000 0.000 0.000 0.000
#1: 1.000 -1.000 1.000 -1.000
#2: 1.000 -1.000 -1.000 1.000

my 4 and 5 pads were messed up so i entered this
mmix 3 1 0 0 0 0
mmix 4 1 0 0 0 0

and now have this
Motor Thr Roll Pitch Yaw
#0: 1.000 0.000 0.000 0.000
#1: 1.000 -1.000 1.000 -1.000
#2: 1.000 -1.000 -1.000 1.000
#3: 1.000 0.000 0.000 0.000
#4: 1.000 0.000 0.000 0.000

now to add motor 3 to channel 6
mmix 5 1 1 1 1

now to add motor 4 to channel 7
mmix 6 1 1 -1 -1

now looks like this
# mmix
Motor Thr Roll Pitch Yaw
#0: 1.000 0.000 0.000 0.000
#1: 1.000 -1.000 -1.000 -1.000
#2: 1.000 -1.000 -1.000 1.000
#3: 1.000 0.000 0.000 0.000
#4: 1.000 0.000 0.000 0.000
#5: 1.000 1.000 1.000 1.000
#6: 1.000 1.000 -1.000 -1.000

image shows motor tab with motors powered up and motors 2,3,6,7 are spinning up! #2 spins up motor 1, #3 spins up motor 2, etc. so it seems to have worked.

just need to set motor direction and then test

UPDATE 3/4/16
i stripped off the exterior board and power supply down to the bare tx and it has been working fine. the only gripe i have is the connector is smaller than most vtx and i have not been able to find any.
Lawmate R1200-Plus and TM-121 VTX, new purchase from hobbywireless 8/25/15

i ordered the lawmate rx1200-plus but received the rx-1260, the invoice says rx1200-plus. hw support has told me the only difference is that the rx-1260 has channel 1258 added, which i have confirmed.

Group A
CH1. 1200.CH2. 1240
CH3. 1258
Ch4. 1280

TXV1012-Plus Dual Power 500/1000mW 1.2/1.3 GHz "Plug & Play" Transmitter
says TM-121 on the vtx
- High quality microphone
- Audio volume control
- High quality 12v voltage regulator for camera and transmitter (no heat and noise free)
- Reverse-Polarity Protection (avoids damage if you plug the battery pack inverted)
- Power output for 12 volt cameras.
- Molex connector with safety latch (prevents connection to come loose while in use)
- Power LED (helps to identify bad power connection, reminds you to disconnect power when it’s not in use)

Decided to set the Osdoge and Naze32 up like i saw at http://fpv-flightclub.com/ they have some great photos and tutorials and sell the 2 ready to go.

first off test both boards while hooking up to USB and loading the latest firmware. There are many how to's on how to flash the Naze32 as it is in the Baseflight chrome app. It was hard to find how to flash the Osdoge but it was in the http://www.mwosd.com/ website under install guide
how to flash the osdoge with the latest fw:
1. Download and install Arduino software for your system
a. http://www.arduino.cc/en/Main/Software
2. Download and unzip latest MWOSD
b. There’s 2 folders it creates. One for the source package (MW_OSD) and one for the configurator (MW_OSD_GUI)
3. Connect the OSDoge to your computer via its USB port.
4. Launch Arduino software
a. Go to File > Open and browse to open the file named “MW_OSD.ino” from the source package folder.
b. Go to Tools > Board > Select “Arduino Pro or Pro Mini”
c. Go to Tools > Processor > Select “ATmega328(5V,16Mhz)”
d. Go to Tools > Ports > Select the COM port for your OSDoge
e. From the menu, click on the Upload icon to flash the OSDoge

After flashing the OSDoge grab the latest MWOSD gui, found at http://www.mwosd.com/. i am running win7 64 bit and could only get the 32bit version to...Continue Reading

I have 2 identical QAV400's except for the FC, one has vector and the other Naze32. I have really been liking the Naze32 as it is so responsive and smooth. When flying manual and you set it on a course with no more stick inputs it is like a arrow, flies straight and true until the next command.

The vector flies great and was very crisp but it would never fly true, it always had a slight wavering when there were no stick commands.

So i really played around with the PID's and ended up with this. seems to fly very crisp and when there is no input it follows the line very true.

Vector GPS RFI Interference Shielding

Was having problems with the vector loiter so tried shielding the gps with copper foil and it really helped. went one step further and cut open the top son the gps had a cleaner view of the sky.

Apparently gps signals are so weak that any rfi from your vtx or gopro will have some effect on the gps
here is the vector after the fix
