iNav help line
#1
I hope this is a better home for the discussion I would like to initiate. I started a thread on 02-March-2017 on tuning PID tuning a 500 mm quad and it has been a very useful exercise. I started with a quad fitted with a BeeRotor F3 and after 3 month of frustration I decide to ditch the BeeRotor using BetaFlight in favour of the same frame fitted with a Flip32-OmnibusF3 using iNav. A suggestion was to flash the BeeRotor with iNav (iNav_1.7.0_SPRacingF3.hex), easy enough after finding the instructions on the iNav Firmware page quite confusing. And the BeeRotor was transformed from a beast to a well behaved quadcopter.

The specifications for the BR quad are

Flight Controller BeeRotor F3
BetaFlight 3.0
betaflight_3.0.0_SPRACINGF3
Frame Hobby King X550
'Wheelbase' 500 mm
Emax MT2215 935 KV motors
ESC SimonK 30A
Props Gemfan 8X4.5
4S batteries

Now it is the same but flashed with iNav.

The story now gets interesting I ordered a couple of Omnibus F3 FCs, one from Banggood and soon after from Ready To Fly Quads as I had read that the Banggood one had problems with the onboard power supply. The BG example let the magic smoke out the instant I connected the Vat but found the FC still worked. This is where I now need help it flies as best described “Tazmanian Devil freak out” a term used in BetaFlight circles. As a resident in Australia I will call it for what it should be a Tassie Devil freak out. I am quite happy to help anyone that may have some questions but at the same time I need help.

The specifications for the Omnibus F3 quad are:

Flight Controller Omnibus F3
iNav 1.7.1
iNav_1.7.0_SPRacingF3.hex
Frame Hobby King X550
'Wheelbase' 500 mm
Sunny X2216-9 1100 KV motors
ESC SimonK 30A
Props Gemfan 8X4.5
4S batteries

PS I need help much sooner than expected, I wanted to reflash the firmware, that part was easy but now I cannot open the Configurator can anyone help please.

Great idea Hank, we definitely need an iNav thread. I've got a Beerotor F4 that I've just flashed with iNav and will be installing it on my TBS Disco this weekend and just waiting for the GPS module to show up. As for your configurator problem, I'd just try deleting it from your computer and downloading the latest version from the Chrome Store.

How does iNav fly compared to betaflight? is it usable on a 5-6 inch "long-range" miniquad with GPS or is it better to just stick to betaflight?

GPS/RTH etc. in BF/CF is more of an afterthought and functionality is minimal. From what I've seen in research and videos, 220-250 size mini quads fly really well with iNav while still having the benefits of position hold, RTH, etc. Remember, iNav is just a fork of Cleanflight, so the devs already had a good start. The cool thing is that configurator and all setup, adjustment is just the same as Cleanflight so it's not like we have a whole new system to learn.

Thanks RENOV8R for your first reply. I can get iNav configurator to work with my second Omnibus board but not the first, the error message is:

I may have to take a week or two off as my mind is in a real muddle

Hank, I know exactly how you feel.

I would say that you have selected the wrong com port.
If i open the configurator and click connect without a drone connect to it you will get that message.
The easiet way to get a connection is to enable select auto connect in the top right corner, if you then plug in your quad then the configurator knows automatically which com port he must use.

I may have a damaged FC, I now notice when I apply power the blue LDE turns on and the red LED flashes a couple of times the settles to three quick red flashes and two slow flashes. This pattern repeats over and over.  Huh

Did you already try to reflash the board with iNAV or try it again to flash it with Betaflight and look if everything will working fine, then you know if your board is broken or not.

HI Hank, answered your question in the other thread. Sounds like your accelerometer isn't calibrated correctly. Accelerometer calibration in iNav is much different than Betaflight.

Thanks again guys, 

Ikkuh I reflashed the board with BetaFlight. The Firmware flash is good but BetaFlight configurator won't respond so I guess the board is no good. Annoying but not the end of the world, bit like crashing a model plane.
RENOV8R I am in a bit of a catch 22 situation, I can't recalibrate the accelerometers as I can't get the configurator to open. I have done the 6 step acc. dance quite a number of time and always wait for the confirmation.
Now to a slightly more vexing situation, from memory fftunes mentioned I may have the orientation of the FC wrong and this turned out to be true. I was out by 90 degrees see images[Image: eGCIcDzl.png]
OK my bad but I also noticed that the gyro orientation needs to be defined or is the default value  OK if one changes the FCs orientation.
sorry can't load image much as the previous one
Please keep in mind I have a BeeRotor working as expected using iNav so I am almost getting there with the firmware but by no means a guru. I hope to have fitted my other omnibus FC fitted by mid week and fingers crossed it will work form what I have learned.

I found that there's quite a difference between the iNav on my Trifecta (SPF3Evo) and the same FC with the latest Cleanflight on my UAV$99 build. I'm referring to configuration elements not the vastly better GPS functionality.

I think I'll end up working out the tuning of my craft in Cleanflight (or Betaflight) and then transpose that back over to iNav.

I do find some of the iNav setup and documentation difficult compared to Missikn Planner (APM/Pix) and would probably go back to a Pix setup if the mission capabilities were critical. INav is great for RTH though!

Thanks Aaron, hard post to answer. I had zero success with BF and the BeeRotor but the first time I flashed it with iNav it was perfect as far as I am concerned. I purchased 2 Omnibus F3 FCs in the mean time after reading rave reviews about them and had nothing but trouble on iNav. I am rebuilding the quad from the ground up and installing the 2nd FC. This time I know what is the default front of the FC, this vital bit of info is not documented and hope to have success this time round.
I find a lot of documentation confusing as we used to say in IT "written by experts for use by experts" so us want to be experts are left in the dark and learn by experimentation usually wrecking an FC or two on the road to progress.

Before realising my SPF3Evo had more impact damage than expected I flashed to the latest iNav and low and behold in the few months since I updated last a lot of the configurations I was missing compared to a Cleanflight magically have shown up!

So when the replacement board arrives I'll give iNav another go.
