YI 4k Plus vs Thieye 5TE comparison

First a comparison of the jpegs showing cropped and then no post processing, just reduced in size. 2nd set is just reduced to 2100 x 1575 (3.3 MP), no processing.

The Thieye looks like it does processing in camera, iso 400 sharpness soft, AWB.
The Yi 4k+ , iso 400, color flat, low sharpening, shutter auto. For color it has YI or flat, with flat AWB is disabled. You can also shoot JPG with DNG (raw).

Next set is the YI dng file converted to jpg and resized

EzUHF NanoRX Receiver

ImmersionRC tools setup, firmware upgrade and binding

There is no NanoRX ImmersionRC tools so select the 4 channel rx. the FW is on the NanoRX

It comes with a MMCX to SMA cable. The MMCX is a push in/out connector

To bind the NanoRX, put TX in bind mode, power NanoRX and push bind button within 5 secs. can also be done through ImmersionRC tools. Took several tries to bind. Make suer both are using same FW and Frequency.

There is no manual. I have been bugging Immersion about this as i had to do a lot of searching trying to figure out how select the NanoRx in IRCT's and how to attach the connector

UPDATE 2/18/17
this gimbal seems to change its mind all the time, had it working for several flights and then the next day it did not work and after wasting hours trying to get it to work again, even with several different receivers (ezuhf, r6208 sb, r617fs) i gave up and just left it in default mode where it seems to work quite well, although it would be nice to ahve the modes -pan - tilt

got the Feiyu Tech 3-axis mini 3d gimbal and was trying to get the pitch to work through the rx. using futaba 8fg with ezuhf 8 channel lite and cleanflight

the Feiyu Tech 3-axis mini 3d gimbal pitch control will not work by itself, you have to have; mode - pan - tilt attached to some sort of receiver. the futaba 8fg only has 8 channels available when going through the trainer port. so with the ppm muxed controlling, rudder/throttle/pitch/roll and then a channel for arming, a channel for modes such as horizon etc, a channel for gimbal mode, a channel for gimbal pan and another channel for gimbal pitch, that adds up to 9 channels so i have to sacrifice some channel control.

what i did was just eliminate the gimbal pan control by pulling that signal wire off, freeing up a channel, and then i had all the rest

the gimbal seems to work with just mode and pitch control

if any one else know how to get 9 channels with this setup please let me know

got the QAV500 V2 3-Axis Gimbal Attachment Plate which by chance fits right onto the qav400. cut off the gopro mounting area on the front of the fc plate and the feiyu mini 3d fits perfect. i have the old getfpv 2axis gimbal paired with some 900kv motors and it never had enough power, could barely fly. i got some hobbyking ntm 1200 and with only 3 flight this had tons of power and seemed like it would fly fast and smooth.

the naze is powered off the esc's, the rrosd powers the cam and vtx by separate power straight off the pdb and the gimbal is powered off the pdb. the gimbal goes slack at the exact same instant that the dvr goes blank so it seems like ti would have to be disconnect of the xt60?

is it possible a short or something would also cause a total power failure?

this video had some jello at the start, low speed, the rest was ok with higher rpm. i ran it through ProDad Mercalli V4 SAL+ and it really smoothed it out and made the video almost look like it was a gimbal.

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
