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.

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.

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.
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?
Regards, Otto
I edited with emacs and sed. I viewed the contents in blender.
Hi Otto,
I now have 3DS max 2018. I got it as an educator (I’m a visiting fellow at my local university). So I’ve been working all day on creating a new plane - its a model of a twin boom TVBS that we’re building in CanberraUAV.
It sure has been hard work today to create the model, but I now have it flying.
I’ve put what I’ve done here:
there are two main issues I haven’t solved
- the motors don’t show (crashes when I set the visual frame for ~CS_ENGINE1 and ~CS_ENGINE2)
- the textures don’t show in the right places. I suspect I need a UV map, but so far I haven’t worked out how
Any suggestions on the 2nd problem?
I’d still like to learn to use blender, but I’ll go with 3DS max until I’ve learnt my way around the modelling a bit more.
Cheers, Tridge
This is free for max. 3 Years.
It crashes about a lot of things.
The same work function, but as I turned the right,top knob at the TX(RF8) it crased again.
It depends on the selected Start Model. e.g.
With the B52 Bomber (2 engines) it crashed with another 2 mot Model not.
When I draw one engine, it works with Cessna. When I draw 2 Mots it crashed.
I could report nearly hundreds of situations, again tried the whole day.
Now started with the sample Nexstar by modification part by part in direction Tailsitter.
With the Start Model Twinstar (2 Mots) it works, the props are to see, but looks strange a Tailsitter
with the Fuselage of a Nexstar.
Yes, you have to use the modificator Apply UV Map. (They are different)
You will finde a good tutorial on Autodesk. There is also an airplane, and explained how to apply one Texture
about different regions of the Model.
I will poste on Google my .max file of the Caipirinha as sample for you.
Regards, Otto
