EDIT: This is now fixed... ignore this and use the latest BASEFLIGHT configurator and associated software load


******************
I had many challenges getting baseflight fixedwing running and operating in the correct directions. So here are the steps....

#0 - if your having trouble, it might not be you why? ....
#1 - The servo directions are broken in configurator....
#2 - The servo mixer works, but unfortunately the numbering convention doesn't match the Naze so use of common sense and lack of manual = failure
#4 - Your probably here because of #1 and #2 !



Connecting up Naze32 and updating Baseflight software

Plug in Naze32

Install Google Chrome

Install Baseflight configurator from google chrome web store

Launch Baseflight

Click Firmware Flasher

Select latest stable (2015.2.12 - 12:04 is latest at time of writing)

Click Load Firmware (online)

Click Flash firmware



Setting up Baseflight

Click connect on Baseflight configurator
Click CLI
Amend, Copy and paste the following into CLI data entry line (where it says "Write your command here") and press enter

Note: change + to - to change direction in smix below
Note: change +100 to +50 to reduce rates by 50% in smix below
Note: check which ones you really want - especially retarded arm, failsafe etc.

Note: get servo directions for gyro / levelling going in correct directions by changing mixer - and then change the directions on tx

Tips:

I removed the 2* foam inserts from behind the pilot seat and cut a base from liteply.
Makes for a massive area to fix servos, flight controllers etc to.

Lovely, just one question - what GPS are you using? Didn't even think to add a GPS, but seems like a good idea .

Got a spare Minim on the way, and already have a spare Naze .

Sorry din't see these posts! Didnt know anyone my ramblings!

airbagit - dunno why did. must have been a bad one! I'll add a couple..

add1ct3dd:
GPS was a $4 ublox one - and crap - have since replaced it. I have a really nice skylab mtk one. Small and light - but unfortunately baseflight doesnt support it. I might have a go to add in...

I recommend these - they are brilliant. HAve done a lot of gps testing and theses are the best I have used so far. Sat counts in high teens - incredible. Also cheper ebay version if dont mind the wait.

SO loaded up new software oand it works great.

I use headtracker on the Drfiter so found out I had to revert back to the old custom airplane mixer to get it working.

Final setup - with headtracker on mixer ch5 and 6

Original ublox GPS was crap and unreliable. So bought a skyl;ab one. MTK based. small and light. Perfect - or so I thought...

Just couldn't get it to work.
Digged into the baseflight code and unfortunately although its an option on GUI - it doesn't support MTK init.

So set baseflight to 9600 and 1 hz and bingo it works - although screen updates are horribly slow.
