My new Hero FC arrived to day so now I have two FCs to play with.

How will the iNav Hero stack up against the Naza M I wonder?

Only time will tell.

Hi Reno, thanks for this tip. IT is now flying very nicely indeed at 75% Atti gain.

I increased TX endpoint to 100% on all channels and dropped Atti gain in two stages, 85% and then 75%.

I am going to go one more step, probably 65% but my gut feeling is 70% will be the best setting.

Things are moving along so smoothly I can hardly believe that one week ago I was enmeshed in maximum turmoil.

Now, I feel that I am within one more flight of hovering the battery out over the spot in my tiny backyard.

How quickly things can change.

Fantastic! About the only tedious process left is to calibrate the 1st and 2nd level warning voltage calibration..........

I cannot wait!

Reno, I have reduced to Atti gain to 65% and IT is still very touchy to fly. I barely touch the sticks to correct any drift.

How far can I go down in Atti gain, do you know?

I tried reducing the TX endpoint again but found that at about 85% I could not arm the motors so I am now back to 100% TX stick travel.

Still, everything is working well and I am getting longer and longer flights although not my goal of 4.5 minutes yet.

KK.

I've got my Atti gains both at about 100% but then my Tarot 650 Sport is probably a fair bit lighter than IT. I'd say leave them where they are and play with the basic gains now. Try these basic gain settings to start:

Pitch: 130%
Roll: 100%
Both Yaw & Vertical: 100%

These are roughly the settings I use on my Tarot so I'm thinking they may tame the IT down a bit.

Maybe also use more expo in the tx?

Thanks Reno, will do.

Thanks FF. I rarely use expo and I had completely forgotten about that approach.

Will do on that one as well.

Howdy Boys,

Things are just starting to settle down and I am in the middle of fine tuning the parameters.

TX expo set at 30%, basic Atti gains 110%, Atti gain 70%.

Took my first sets of graphs out of the ESC data loggers today. (see attached photo.)

That data is from motor 1.

It is now starting to become very interesting instead of very frustrating.

I will keep you posted on progress.

KK

PS When looking at that graph remember that I am just trying to do one job and that is to hover out the battery in one single flight, over the spot and at 30cm altitude. As you can see from the graph I still have not achieved that but I am getting closer.

   
Howdy All,

The attached graph is an interesting one.

The two false starts at the beginning are due to me switching the three position mode switch to Atti (middle) for the very first time.

All previous flights have been in manual mode.

As soon as I opened the throttle IT jumped off the ground and was a meter high before I knew it. I put her down on the ground and tried again. Same result.   

Now this was far too frisky for my little backyard so I switched back to manual and as you can see and I hovered out the rest of the battery charge in one single flight (finally).

So my question is what can I expect in Attitude Mode? Is that normal behaviour?

KK

Congrats on completion of your 1st personal milestone, with hovering out the battery!
Re. behaviour of attitude mode, the only thing I can think of, might be calibration of the sensors, maybe Barometer?
Remember though I am like Manuel from Faulty Towers, "I know nothing"

Tom!!..........I was wondering where you had got to. Welcome back!

I tried re-calibrating but my computer argued against it saying it was unnecessary. And who am I to argue with a computer. I am silly, but not that silly.

Anyway I will keep looking for answers on that Atti thing in the meantime I have changed a few parameters so I will see how that goes.

So it is onwards and upwards, ever upwards.

KK

Howdy Boys,

I am now trying a new tactic and that is charging for 20 min and flying for 1 minute.

The aim is to find the best settings ASAP.

I am now down to 85% basic and 50% Atti gains.

IT is now finally starting to hold position and flying quite smoothly.

I tried the Atti mode again and I found that the throttle behaviour is quite odd.

Slowly increasing throttle results in a dead zone mid throttle and then BOOM!.

IT jumps three feet in the air.  

Weird!!

I need to find answers for this one. It sounds like there is a barometer or something hiding in there.

KK

Howdy again,

That last setting was magic.

Basic gain 75%, Atti gain 50%.

IT is now holding position well and is very docile to fly.

I am not too sure how far I can push this.

Atti gain cannot be set below 40% I just found out.

Next flight the gains are Basic 65% and Atti 40%.

We will soon see if I have pushed it too far.

KK
