Eagle Tree Vector installed in a QAV400, Advanced Gain Settings

After thousands of flights with the trusty KK2 i am now trying the Vector in my QAV400. I only fly in full manual (3D vector speak).

As the KK2 the Vector is totally configurable in the field but is done through the OSD on the monitor. There are so many options that it is very overwhelming at first coming from the simple world of KK2.

The Vector is mounted a bit forward of it s recommended CoG so that I can get the battery far enough forward to maintain the QAV400 CoG, it seems to have no effect on the flight characteristics.

After 20 flights I am finally getting it dialed in through the Advanced Gain settings as to where it feels as crisp and responsive as the KK2.1.5

It seems very smooth and responds quick to stick commands. It does not have the jitters / oscillations when dropping down in a hover that is found on the KK2, very smooth dropping down flat

These are the current settings as of 7/26/14

Both controllers are in full manual, that is all I fly in.

First clips shows my trusty KK2.1.5 which has hundreds and hundreds of flights. It flies very smooth with little oscillations for the type of flying i do. it is a balance of control or oscillations.

2nd and 3rd clips show the Eagle Tree Vector FC i just installed. I tried just adjusting basic gains and i did get rid of oscillations but i did not have the locked in control feeling that i had with the KK2. So i enabled the advanced gains to tune through PID. You leave the "Controller Gains and Responsiveness" Pitch/Roll/Yaw at 100% and then tune through the PIDs.

This is just the first tuning with the PIDs on the Vector and it seems more locked in already.

Myself and several others were having problems setting up the Vector with the EZUHF to get RSSI and LINK readouts.

I upgraded the EZUHF rx and tx to 1.50. I updated the Vector to Fw 1.38 although it has a big WARNING about how it might be unstable.

In ezuhf tools i selected ppm muxed on the servo output and rssi on ppm slot 11 and link on ppm slot 12.

In vector config select rssi as channel 11 and link to channel 12, hit apply.

Now run vector rx wizard and if you have success you should see the rssi on receiver status as 100%. under serial ppm rssi should be channel 11, link quality ch 12. under serial ppm servo positions ch 11 will read 0% and ch 12 reads 80%. This is with rx and tx on.

here are screen shots of the vector config and osd with tx on and then off

ET support has been stellar and this is what they responded with and posted on forums:
-----------------------------------------------
Hey, wanted to post some troubleshooting steps for configuring and displaying RSSI/LQ via the PPM stream.

STEP 1
The first thing is to make sure you've installed our beta software 11.26 or later, found here.

STEP 2
The next step is to confirm you have correctly configured your Rx to output these readouts correctly, per your Rx instruction manual. You can test that this is correctly configured by looking at the channels corresponding to LQ and RSSI on the "RC Configuration" tab in the Vector software, in the "Serial PPM/S-BUS Channel Mapping" Section

Vector, Futaba T8fg and ezuhf throttle failsafe setup

I was able to assign a sub-mode switch to enable RTH but could not figure out how to make Throttle Failsafe work with ezuhf and Futaba T8fg

Turns out it was very easy
Trim your throttle all the way down which on a Futaba T8fg reads +50 when you trim down T3. Now with TX and RX on hold the failsafe button on the ezuhf tx until you hear a series of beeps. This programs the rx what to go to when it looses bind. Next dont forget to put your throttle trim back to 0.

Now run the vector rx wizard and select throttle failsafe and you should have success.

Here are Us reading from the Vector Rc Config tab/receiver input monitor
throttle trim all the way down
throttle down 1002 us
throttle up 1950 us

o throttle trim
throttle down 1101 us
throttle up 1950 us

Found this over at fpvlab

The ezuhf will usually bind after the escs power up so you won't be able to enter ESC throttle calibration. This way of the throttle is at full when the ezuhf binds so you can calibrate.

1. Set throttle to max. saved settings to EzUHF, hitting 2secs on the EzUHF failsafe button, confirmation beeps.
2. Connected ESC to CH3 on the receiver
3. Listened for the ESC tunes/beeps.
4. Throttled to minimum and listened for the ESC confirmation tunes/beeps.
5. Same procedure on the other 3 ESC.
6. Afterwards set throttle stick and switches back accordingly and saved settings to EzUHF, hitting 2secs on the EzUHF failsafe button, confirmation beeps
7. Powered up, connect Naza to PC. Checked that failsafe acted accordingly when radio turned off (no props on ofcourse).

Using KK2.1 V1.16S1 Updated Firmware
The firmware now supports the following receivers: -
Standard PPM
Combined PPM (CPPM)
DSM2 satellite (bind on power up holding down buttons 2&3)
DSMX satellite (bind on power up holding down buttons 3)
SBus

This reduces the wiring between the KK2.1 and the EZUHF down to 1 servo cable. Attach cable to CH 1 on the EZUHF and Channel 1, Aileron, on the Kk2.1

Hook up EZUHF RX to usb and go into Immersion tools and select Servo Mapping and change CH1 to "PPM Muxed". Upload settings to RX

In KK2.1 Menu select Mode Settings> Receiver> CPPM
Now power cycle the KK2.1

Go to Receiver Test in the Kk2.1 and the channels should be working.

Qav400 went down today and would have never found it without these:
PT-1B TRANSMITTER
PR-100A RECEIVER

it was out 3/4ths of a mile and nowhere near where it thought it would be.
the pr-100a led me right to it. 5th time ive used the system and has easily paid for its self!

wanted to mount a gimbal on my spare qav400 since getfpv has not released theirs yet. then i saw that FFBLG offered a adapter and mounting plates for the qav400

i used the alexmos board from my qav500 and the main part from a beholder lite gimbal i had made into a handheld gimbal.

i cut off 1/4" from the front of the qav400 so that the roll arm would clear the frame. i didnt use the vibration system that mike offers as the qav quads have amazing a vibration dampening system with the bobbins. to get a little bit more clearance on the roll arm i added a nut onto the bolts between the frame mount and motor mount. bolted the beholder gimbal to the ffblg motor mount

powered up the alexmos and it seems to work excellent with the stock settings from the qav500 gimbal!

here is the first test flights and it seems to be working well

I had totally forgotten to this is in awhile. I was putting new bearings and shaft in one of my MT2212-13 motors that has probably over 1,500 flights on it. I found the grub screws that holds in the shaft to be loose by one turn. I was rebuilding the motor as it had been in the river and had a lot of up and down play. New bearings and shaft and I have zero play

I checked the grub screws on the other motors and sure enough they were all loose. If you have up and down play, loosen the screws, tap the bottom of the shaft to bring it up into the motor housing, add locktight and tighten the screws, no more play!

KK2.1 Quick Start Guide

This is for 4 motor quads as that is all i have set up and assumes you have the quad pretty much built up and ready for the KK2.1 install. This guide also assumes that you have your Transmitter and Receiver all set up and bound.

Use Google to search as there are TONS of videos and tutorials on all of the following steps and much more.

Before installing flash the KK2.1 with the latest firmware and instructions found HERE and HERE. The USBasp will provide power so you can flash and program.

After flashing select type of quad you will be flying in Load Motor Layout, For QAV400 and similar use Quadcopter X.

Now go to Show Motor Layout and take note of the motor and esc numbers, configuration and which way the props spin that has been assigned to the motors. 1 through 4. I label the ESC connectors that will plug into the KK2.1 so as not to plug in the wrong ones. I also label which way the props spin on the arm right next to the motor, really helps when you are taking props on and off. For example Quad X has motor 1 as front left motor and it spins clockwise.

Go into Sensor Test and make sure everything is OK

Go to Mode Settings and select whether you want Self Level to be done by Stick> Turn on Self-leveling by holding the aileron to the right when arming. Turn it of with left aileron or AUX> is where you assign a switch on your Transmitter to turn Slef Level on and off, Channel 5 on most Tx's and Rx's

KK2.1 and QAV400, initial tuning

Previous kk2 settings for flat out fpv runs, dives and hillside proximity
Roll/Pitch 50/100/50/20
Yaw 67/20/67/10
Stick Scaling 40/40/50/90
TX Expo 40

KK2.1 settings, FW stevis 1.10
Roll/Pitch 300/100/225/20
Yaw 225/20/175/10
Stick Scaling 9/9/9/90
Self Level P Gain 50 - P Limit 20. Acc Trim Roll Corrects left/right while drift while in sl, i set to -8 as it was drifting right. Acc Trim Pitch is forward/backward drift
MPU6050-SETTINGS Gyro 2000, ACC 4, Filter 256
TX Expo 45

I would think that the stock settings for the FW HK 1.6 in PI Editor (Roll 50/100/25/20, Yaw 50/20/50/10) would be so tame as to make it zombie like but if you were in SL just starting it might be ok for first flights. The Stick Scaling (30/30/50/90) on the other hand would make it so sensitive you might have a hard time controlling it unless you had tons of expo in the TX. The stock P Gain and P Limit (100/20) in Self Level make it really snap back to level. 50/20 is more tame and not as abrupt.
