Building RealFlight8 Models

great!

to fix that just follow the instructions here:
http://ardupilot.org/dev/docs/sitl-with-realflight.html
KnifeEdge have opened up their LINK registration page, so you should be able to do it now.

MP already has support for talking to RealFlight
Do you want me to do a demo video showing you how to load and fly the C7 model from scratch?

try using a 2D photofield instead of the 3D airports. I always use a 2D photofield of my local flying site at CMAC, not only because it matches where I fly, but also because it is less graphics intensive for my slow windows laptop
Also turn all the graphics options in the setting down to minimum

Had a short look (Repair graphic has priority) at this Page https://www.knifeedge.com/cart/index.php?main_page=product_info&products_id=181.
Didn’t check whats the function or target of it.

This would be great because your tutorial videos where very helpful.
Especially the part, setup MP for Simulator, connection to RF8. (or is this the target of the LINK)
But I must say, didn’ read Using SITL with RealFlight — Dev documentation yet.
I’m just a litle behind your recommendations. :confused:

Could be helpful for others.
But I know, you are havy charged.

Regards, Otot

try that first, Randy has tried to make it pretty clear
If you get stuck I’ll do a new video showing it using RF8 and your TVBS model
Cheers, Tridge

OK, of course will be next because the graphic works.(for me)
Here the new Files: https://drive.google.com/open?id=1PF47Lgz6Yc_jWSYbHD7esyJ7S_tCWs7o
The name of the .TGA File has to be maintained, because it looks after that in the file.

I selected, while importing, your Aircraft C7-3 and all Parameters where set.
Now, the aircraft only crashes…

Perhaps, a bottom start my be possible.
I use Carbon Props like this.

(Thy looks a bit less heavy) :wink:
Regards, Otto

fantastic, looks really great!
I’ve done a video here

I’ve also updated the RFX and parameters in the SITL_Models repo

Hi Andrew,

I’m happy that you are satisfied and thank you for the good video presentation.
You did the link to RF8 setup perfect. It can be used as Tutorial for others.
I did not compare the params you posted with mines yet. I find your Caipirinha flies more stable.

What about a non vectored Tailsitter, like Palm369, you know those with the “butterfly mode” during auto mission.
I already made the raw drawings on the base of CAD Datas of him.
If you are interested I would complete it to the same state as my caipirinha.
This one:


Regards, Otto

For the last video I adjusted the tuning gains a bit to increase stability

that would be great!
We’ll need to set it up so it starts with the props pointing up like a tailsitter.
Thanks!

OK, will continue when I got the infos from Palm369
Kind regards, Otto

Cough, how about an Arduplane sticker on each of these models… What was butterfly landing mode Otto? Shutting one motor down and sycamore seed rotating down might be fun. Cool take off mode after a stiff chuck.

Yes, thats a good idea with the sticker.
Whats the meaning of Tridge?

No not butterfly landing.
Butterfly flight mode like this.

Hi Tridge,
Here the Files for the non vectored Tailsitter of above.
https://drive.google.com/open?id=1s-iICWrAnf8E8c3NjexnqP4g8oTCzcrj

I didn’t get the specification from David so far.
But I hope you can use it with your own data.
I could import it to RF8 without issues.
But editing is still difficult, because crashing after “exit edit”. Even with standard Models.
No answer from KnifeEdge Support so far.
And with this issue, will wait with the link to MP.
Try to install RF8 on another PC. May be Win7, 64Bit,Ultimate does not work with RF8.
Regards, Otto

Thanks!
I fixed a couple typos in the FBX file (using a binary editor):

  • CS_SPINNER1 → ~CS_SPINER1
  • ^CS_LMW → ~CS_LWM
    I also think we should use only ascii chars - the german characters in some of the parts don’t display for me. I don’t know if they cause problems in RealFlight.
    I’ve put together an initial physics model, RFX file here:
    https://github.com/ArduPilot/SITL_Models/tree/master/RealFlight/Tridge/TailSitters/Cat
    unfortunately when I start the motors RealFlight dies immediately. I’ll post something on the RF8 forums and see if anyone can work out why.

I’ve now got the Cat tailsitter flying - it turns out RF8 doesn’t handle the german characters in the names. I did some more binary editing and I can now fly the model. I’ll do a video soon.

Here is a video of the Cat flying:


plus I’ve uploaded the model and parameters to:

Hi Tridge,

Thanks for the Video.
Yes, you are right. Not a good idea to make the design on top like on bottom.
Will change it.
Did I make an error that the props are not to see?
Regards, Otto

Edit:
Will have a look about german characters in the File too.

Did I understand right. You had to change ~CS_SPINNER1 to ~CS_SPINER1 ? (With one “N” only)
Because in the manual it was wrote with 2 "N"s.
https://www.knifeedge.com/KEmax/plane_tutorial.php

Yes, my fault.
Otto

It was missing the ~ at the start, and I needed to keep the string length the same when binary editing, so I removed an N to make it fit

I’m not sure - I can’t pick an engine type at all in this file, so something it different from the TVBS model, but I haven’t worked out what yet

Here the modified files
https://drive.google.com/open?id=1Y_Gvkyt_HCWcCei43x9fq1fSMIxI53n5

Also the .TGA is new. (Color scheme top, belly) both with the same name.
When I import it to RF8 with the start Model e.g. Cessna then in crashes. (one engine only)
But when imported with the start Model caipirinha2, it works.
But can’t see the props, even with exacly the same names (~CS_ENGINE1) OR (~CS_ENGINE2) and the same
linking to the base (~CS_MOUNT1),(~CS_MOUNT2) which are linked to the wing.(~CS_LMW) …

The Props are named: ~CS_ENGINEx (as with caipirinha2)
The Motors as : ~CS_SPINNERx (so it shows the motors spinning, as in caipirinha2)

When a make cat with one Prop (ENGINE) only and as start Model Cessna then I can see the props of the cessna
but in a wrong direction to the vertical cat, of course.
Strange…
Regards, Otto

It also looks like it doesn’t like spaces in component names. Removing the spaces from the components got rid of some of the errors, but still doesn’t display the propellers

Sorry for the need of repairing.
I had to export, import, start, delete, restart RF8 and redesign with one part, one more, again one more in order to to finde the error.
This because of no inteligent error message of RF8 and simply crashes.
Took me the whole day, wife not happy.:wink:
I replaced German characters, spaces in names, deleted all anused Objects and read
serveral times the manual to check the link conventions.
But will check the names again. Which names did you finde with Spaces?

By the way. RF8 runs on another PC, with Win 7 64 Bit. Back from the Editor the top menu is gone also
but moving the cursor at this place the menu Text comes again at that place where the cursor is.

Which tool do you use to analyse the binary .FBX?
