What's expected here is that the scorpio can't find such object, neither can the AH-1. Literally the object named there are missing from the ac. So its accurately a fix for both models (in the sense of silencing the err).

A better fix would be identifying the correct object name and fix that.

You quite funny. I don't have stomach to digest that

gonna try that out.

I hope it inspires someone to make a 3d model for it..

Im quite tempting to hotstart a blender and add the turbines of the scorpio. Will report.

If we gave everybody in the World free software today, but we failed to teach them about the four freedoms, five years from now, would they still have it?

To explain it the turbines charge up the Ultracapacitor... the 4 electric rotors run off this Ultacapacitor.. Once the turbines stop charging it, there's sufficient energy reserve at 100% full to fly for another 2 minutes.

@Bomber

I know already I dont have a lot of talent in 3d development

But for the fun of it, while something better comes along (if it comes along)

I made this

And yes, as you can see in the commits the blades do rotate

This hover mode is either witch-crafty or a cheat

There's no way otherwise I could've done this:

Yeh I know what you mean about the hover mode, when I first got it working I thought I'd accidentally paused.

To show it's not a cheat, turn the wind up and put severe turbulence on...

The model looks brilliant, I'm going to download it now

it would seem you can land on these....

The FGUK download link on the FGMember AH-1 fails to work.. should be

http://www.fguk.me/hangar/rotary/summar ... supercobra

I appreciate they can change it at any time, but it takes no time to copy and paste the correct link and always best to not give people the opportunity to make negative comments

You might want to change the rotor animation to this, so as they're linked to the motors and not the turbines

Code: Select all

<animation>
  <type>spin</type>
  <object-name>helixL</object-name>
  <property>/fdm/jsbsim/propulsion/engine[2]/propeller-rpm</property>
  <factor>-1</factor>
  <axis>   
   <x1-m>-2.75938</x1-m>
   <y1-m>0.41190</y1-m>
   <z1-m>1.92119</z1-m>
   <x2-m>-2.93957</x2-m>
   <y2-m>0.42226</y2-m>
   <z2-m>1.50897</z2-m>
  </axis>
</animation>
 
<animation>
  <type>spin</type>
  <object-name>helixR</object-name>
  <property>/fdm/jsbsim/propulsion/engine[4]/propeller-rpm</property>
  <factor>1</factor>
  <axis>   
   <x1-m>2.91140</x1-m>
   <y1-m>0.23429</y1-m>
   <z1-m>1.85149</z1-m>
   <x2-m>3.10399</x2-m>
   <y2-m>0.23951</y2-m>
   <z2-m>1.45029</z2-m>
  </axis>
</animation>

Also forgot to mention the rotor file on the download throws up an error.... that might be intentional, I don't know.... I was thinking that a readme file explaining the rotor issues and solutions might be a good thing to have in the engines folder.

And whilst talking about it,..... could someone not banned over on Flightgear forum bring the propeller rotor power table problem to the core devs attention..... you don't have to advertise the Scorpion (although would be nice, to get a larger audience) but I think for normal propeller planes it's important.
