Title: UAVs - post your UAV here
Post by: daveapplemotors on January 06, 2016, 05:05:27 pm

SAMPLE: attachment named "sample.uav"

I think we need a repository for UAVs like was on the OP site.

I will start with three 250 CP helicopters:
Blackie and Amarillo are HK250GT (originally) - Chinese weights and dbl bearings in tail, Tarot FBL heads,

 DJ250 is a Trex 250 with DFC, Chinese weights, dbl brgs****warning** this heli has some pitch wobbles. Yaw and Roll are great but pitch oscillates.

Edit: I corrected some of Blackie's data. New 1307Blackie.uav
Edit newer flies for Blackie and DJs250

Do you know you can share templates that can be included in next release ?

Tools > Import/Export vehicle template

Laurent,

I do now. Thanks for pointing it out. Is it something for the future that doesn't work yet?

I filled out the entire form and included a photo of Blackie but it won't let me save or Export.

I see that Import can include current tuning as well as the vehicle profile. Will it include the entire UAV?

Template already works and used at wizard end (but not for helis)

If you created a template, it should be displayed later in "Import" list and saved in your config dir.
Template store main parameters for stabilization but not include Rcinput numbers for example.

Templates can also be used without using the wizard. To apply a template to a board, or exporting/importing a template just go to the 'Tools/Export/Import Vehicle Template...' menu and a dialog will open allowing you to handle templates in an easy way.

Template:
Under Export I created a new template twice and never got to the save or export part. What did I do wrong?

Title: Re: UAVs - post your UAV here
Post by: f5soh on January 08, 2016, 06:04:06 pm

"Save as" and "Export" are only active when a board is connected ?
That allow retrieve settings.

Title: Re: UAVs - post your UAV here
Post by: m_thread on January 08, 2016, 06:11:24 pm

Yes, you have to have a board connected to be able to ''save as'/'export' any template. The dialog might be improved. The wording on the buttons should probably be changed to something more descriptive.

I tried with board connected before. It is connect right now. and I don't see it . I don't see Export or Save highlighted

Some inputs are not mandatory:
Name, owner, forum name, size, weight and need at least 3 or 4 characters in some cases

Title: Re: UAVs - post your UAV here
Post by: daveapplemotors on January 08, 2016, 06:42:13 pm

Yup. Thanks. When I had forum nickname "LP" it didn't work. As soon as I typed "Libr", just 4 letters, it highlighted Save and Export

Silly question and might need a one word answer.  Do the .uav setting files work on the who range of CC3D gyros?  Will a Revo set of settings work just as well in the Atom? 

Title: Re: UAVs - post your UAV here
Post by: daveapplemotors on February 14, 2016, 01:53:00 am

I am finding smaller PID numbers  to work my Revo than what were used on my CC3D Atoms. The numbers were a good starting point.

If you are using different flight modes for PID comparisons Practice and Plan ahead. Today I was flying along minding my own business and testing different PID settings in flight mode 2 when it started crazy oscillations.  I couldn't  switch back into flight mode 1 easily so I had to land with it bucking and wiggling. I didn't plan on an EASY, CONVENIENT switch that I could get to in an emergency.   

I thought they wold be the same but they are not.

Post by: daveapplemotors on February 14, 2016, 02:05:16 pm

All three of these 250s flew well with Open Pilot. They were all stable and quick handling.
Their OP files are posted (OP in the title)

And the LP files are here, too.  2- 14-2016. The PIDs are different in LP.

Title: Re: UAVs - post your UAV here
Post by: daveapplemotors on February 16, 2016, 01:26:55 pm

Two files that both fly one of my HK250s:
Open Pilot  (1108Amarillo) -- and --Libre Pilot (1414Amarillo)

The OP file flies a little better right now. I need more time with good weather and then some wind to tune better.
I will post updates of the Trex250 and my other HK which has a Revo in it soon. Weather permitting...

Title: Re: UAVs - post your UAV here
Post by: daveapplemotors on March 06, 2016, 09:52:04 pm

I flew DJ250 and Amarillo in some wind today. The outer loops are better now. I don't know how many packs I used because I kept 2 chargers busy for 5 hours.

Both fly well but are finished yet. They are up to Microbeast standards but not the previous OP kind of flying yet. They are close.

Post by: daveapplemotors on March 12, 2016, 03:10:40 pm

I have not finished with tuning PIDs on any of the 3 250s. DJ's 250 is getting much better with the UAV posted here. It flew in some wind a couple of days ago. The tail is not right yet but Pitch and Roll are pretty good. I use "Rate" for Pitch and Roll and "Axis Lock" for "Yaw".

I hope to find a relationship between the Open Pilot PIDs and Libre Pilot's PIDs. When I am happy with the way all three fly then perhaps I will see a simple linear correspondence between LP PIDs and OP PIDs.

Title: Re: UAVs - post your UAV here

This HK250GT helicopter with an Atom flies really well. It has a tail that is mechanically very ,very sloppy but it holds perfectly. I add Tail Mix on my TX (-24%) at full thrust and it holds really well on extreme pitch pumps. I fly in Rate, Rate, AxisLock and will experiment with other flight modes soon. There is a large mechanical change since it was tuned in OP. Putting the linkage balls into the inner most of the three positions on a Tarot head required new PIDs. Tail servo is still a Turnigy S308G-HV--Cyclics-HS65MG. 

When the weather improves I will get another video. 

Title: Re: UAVs - post your UAV here
Post by: daveapplemotors on July 10, 2016, 02:56:04 pm

The tail on Blackie, an HK250GT originally, is solid now. I ran 3 or 4 battery packs working on it yesterday. It held well in 10-15 mph wind gusts. I will test in stronger wind when I get the chance.
The tail mechanism is extremely loose. An Inolabs D202HB servo moves a regular metal pushrod for a stock HK tail-- with Chinese weights and double bearings-- and 37mm Trex tail blades. 

Further note re Yaw:
"P" change from .00266 to .0265 or .00267 made a difference. Likewise an "I" change from  0.00139 to 0.00140 or 0.00138 flew sloppier. I didn't get happy about this one until I had 3-place accuracy!

I noticed once I started adjusting outer loop that anything higher than 3.5 got wiggly. I am still working on the outer loops.

Tarot 450 Pro FBL, 6 flight modes to use all the three banks with Attitude and AxisLock settings. Thought for Dx6i.
The heli holds quite well in the wind, managed to do some flips with no issues, tail holds well, but could oscillate a bit with highest RPM. It's still WIP, but it flies really good. Pitch range is limited, to get +/- 12° of collective on my setup.
Attitude holds the heli still in the air, with a slight angle, to compensate tail's lateral force. It's quite aggressive at stabilization, so better to not be used for too fast flights.

Video of the heli with these settings can be found here (https://forum.librepilot.org/index.php?topic=1362.msg15243#msg15243).

Hey ,

Is the swash really level? 
 Top? , middle? and , bottom? with these numbers from your UAV? :

values="2000,2000,1000,1242,2000,1000,1000,1000,1000,1000,1000,1000" name="ChannelMax"/>
            <field values="1500,1500,1500,1379,1136,1000,1000,1000,1000,1000,1000,1000" name="ChannelNeutral"/>
            <field values="1000,1000,2000,1662,1000,1000,1000,1000,1000,1000,1000,1000" name="ChannelMin"/>

And I found that accuracy to 3 significant figures was noticeable. I couldn't use .0022 as well as perhaps: 0.00222 or 0.00223. A change to that last decimal place makes a difference.

Yes it is, as accurately as I can misure without a swashplate leveler. The setup on the heli is pretty much perfect, now I'm just tuning PIDs, as I think that's the only thing which can be improved, well, apart from getting better hardware.

I am trying to setup a LOGO400 with the CC3D Atom.
I can need some help.
Who has a .uav-file for a 500-size helicopter. This would give me a startingpoint.
Thanks

I am tying to setup a Trex 500 with cc3d atom, with futaba sbus

Has anyone a .uav-file ??

Hello Everyone,

I am trying to setup mini helicopter.
It weights like 50 or 60 grams.
If you have any UAV files I will be delighted.

Thanks

Hello,
The smallest size Heli I have seen here is 250 size.
If you look for some of the previous posts you will find several of daveapplemotors UAV files from his HK250GT
https://hobbyking.com/en_us/hk-250gt-electric-helicopter-kit-alloy-cf-w-blades.html
Here are two of mine UAV files from two trex 250's
Could be a good start, but for sure you need to review and adjust settings.
Good luck!

EDIT
1.Here is thread to get a 200 size Heli working

2. Here is another thread by jcg1541 for small Heli for cliff diving:
