installed another TBS Crossfire Micro in another build and took it for a test flight and i was getting these weird vibes sometimes, like maybe the the rx and tx were not updating fast enough, happened 1/2 mile out. here is the log from the 2 flights showing, rssi, rqly and rfmd

X220 - TBS Crossfire Micro - 2K Flight

Finally pushed out past 1K and made it to 2K, only limiting factor was battery. It was 3.90 when i landed. Still had perfect video and the logs from the Taranis received from the TBS Crossfire Micro looked good from what i know.

The TrueRC - 5.8 GHz X-Air has really made a big difference as if you stay in the beam the reception is stellar.

logs with antenna in 90 degree orientation

these are some logs from todays flight with the tbs crossfire micro. i have the taranis setup to log the telemetry from the tbs crossfire. from what i have read the rqly and rfmd are the 2 most important values to monitor for signal strength. these logs show the 2 and this was not a long flight at all, it was just playing around doing some rolls and flips going out about 1/2 mile

i am not sure how to read these that well yet, the image shows a brief explanation of them. rfmd 0 is a very slow update rate while 2 is super fast, super low latency. rqly below 70% is pushing it but some folks go below 60%

TBS Crossfire Link Quality (LQ) Taranis Call Out Warnings
A how to on youtube

First up why LQ and not RSSI, well LQ is Link Quality and it gives you a better representation of the RC link than the RSSI (received signal strength indicator) RSSI values don't take noise floor into consideration so you've never really got an accurate measure of your link by just looking at RSSI

RQly is the Link Quality value
RFMD is the crossfire link mode
0 = 4Hz
1 = 50Hz
2 = 150Hz
When RFMD in in 150Hz mode (2) LQ does not matter and does not need to be monitored.

Logical Switches:
L01: Monitors the Crossfire frequency mode, it then activates when RFMD is NOT in 150Hz mode
L02: Active when LQ is less than 80% and not in RFMD 2 mode, (a pre warning)
L03: Same as L02 but with the critical warning level at 70%
70% is considered the critical level for LQ
The 0.5 is a delay so that you not getting warnings when you get a quick drop in RF

Special Functions:
This does the actual call out to the speaker
SF01 will play sound "RF Low"
SF02 will play sound "RF critical"
The !1x means it wont play at startup
Check your LQ indicator ("Link Quality") to assess your link's health in regards to closeby external interference. The LQ goes from 0% (no signal) to 100% (full signal). Any value above 80% can be considered safe to fly, large drops below that indicates you are reaching the limits of your radio link. Also check your SNR indicator ("Signal to Noise Ratio") for your margin above the noise floor (far away external interference). The CROSSFIRE's LQ will deteriorate once the SNR reaches 0. Anything above 3 is good. The theoretical limit is -6dB. The RSSI indicates the signal strength of the antenna on the frequency that it is listening on. A high RSSI and low LQ indicates high interference, a high RSSI with high LQ indicates very good noise conditions. The RSSI goes from +10 to -130, in a logarithmic scale, with every further 6dB reduction indicating a doubling of your existing range.

X220, Omnibus f4, Crossfire Micro

getting ready to try some long distance flying

this is equipped with this transmitter which i have now used for years and has saved my quads countless times, even a mile out i was able to quickly find it. it is used in conjunction with the PR-100A RECEIVER $249.95 and even though it costs a lot it is well worth it and could be shared among friends. you will never loose your quad again as with other systems if you crash and the battery is ejected you will never find it.

update 11.27.17
flies great, not sure if i notice a difference with the crsf protocol but it did fly very smooth and responsive. had the taranis set to rssi alarm at 80% and it only invoked once going out 1/2 mile behind some trees.

works as wired, i tried tx/rx3 and tx/rx6 and no luck

Pin 1 (receiver TX) goes to one of the flight controller UART RX
Pin 2 (receiver RX) goes to one of the flight controller UART TX
Power up the Flight controller, the CF Receiver will have a RED light (not bonded)
Push the button on the Crossfire , can also be done though lua
Power on the receiver and push the bind button (no need to power up with button pressed like FrSky)
The button will turn blue, the receiver LED will turn green.
This means the bind is done but the TX needs to update the firmware on the RX module over the air (magic!).
Push the Crossfire TX button to confirm the update, wait a couple of minutes until it turns green again.
download tbsagent, lug into back of CF TX, update both TX and RX

taranis x9d+
open tx 2.2 latest
internal rf off
external set to crsf , ch1 -8
rx and tx are bound (both green), see both in tx under crsf lua
configured rx to output 1 and 2= crsf tx/rx , 100mw
Channel Map Dat.Ch. 8 RSSI

betaflight 3.2.2
serial set to uart 6
receiver mode set to> serial based rx
serial receiver set to> crsf
In Receiver tab set the RSSI channel to 8, now you can see the RSSI

eachine wizard x220 - rc-l1 com-spec.com

been using a tile on my eachine wizard x220 but it has a very limited range. will now install this rc-l1, 1 mile range!, transmitter from com-spec.com. i used to have its big brother on my qav400 and it led my right to it when lost over a mile out, several times.

this shows the size compared to the tile mate.

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 setup

ImmersionRC tools setup, firmware upgrade and binding

There is no NanoRX ImmersionRC tools so select the 4 channel rx. use same fw

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 sure 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

to hook up ezuhf tx to taranis 9 use the oinout shown in photo and power with a external 11 volt battery.

Taranis - EZUHF external - BF - Quad setup
Using external EZUHF box
Posted by yosemitez | Jan 18, 2017 @ 06:38 PM | 5,418 Views
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?
