Red face GlobeMonsterⅢ?

The transport aircraft was made. Please teach the setting suitable for this airframe. (Variously ..
the engine, the rudder corner, and weight... )

I can set up the physics, but I need some specs on a similiar "real" RC model to work from.

If you can point me to one, I can fix the physics for you.

What are ideal are RC build manuals, as these frequently have all of the specs including CG, throws, power curves, weights, wing loading, wing sizes, etc.



So is there a real globemaster RC scale model using ducted or turbine engines?

Yes there is ,the ripmax team headed by colin struass made a C17 globemaster 3 for the tv show supermodels which is on discovery channel now and again it has made several successfull flights and i have even seen it fly at a local show last year.It certainly is a supermodel with a wingspan of about 18 feet i believe.I will see what i can find out in the way of specs and post them here.

The C17 was flown for the first time in October 2003. The model was built by Colin Strauss for the Discovery TV Programme "Supermodels". This model is powered by four Jetcat 120 turbines. It is 11% scale with a 5.76m wingspan, 5.90m length and weighs 90kg.
I found this information on the LMA website which is at www.largemodelassociation.com there are a few pictures there also

Here are the specs for the real size one and the model was built to 11% scale so you just need to scale down the specs accordingly and you should be away. Hope this helps

That message usually happens when you have not installed the file properly.

It sounds like you "opened" the G3x file as a zip file and manually installed it.

This is not correct.

You need to IMPORT the .G3X file itself.

See the other threads for full explanations.

THANKS!

That plus the scaling ratios gives me enough to do most of the physics.

The missing parameters can be done right from the 3D model (e.g. aileron lengths and sizes, etc.)

Sheez, so many planes so little time.

(Wait till you see what's about to be released. I think it is VERY cool.

It should be out tomorrow or the day after from the RC Warbirds guys.)

I have been part of the project aswell so i know what is coming.I am responsible for the conversion for g3 and the retexturing.Can't wait.
Also i have done an edit of the globemaster that is roughly 10% scale and i think it flies okay for the mean time so try it out.Although trying to land it without killing the engines is a challenge

Did you do the model?

Very nice work.

I didn't build the model only convert it for G3 and retexture it

Hate to be the fun police, but somebody's got to do it... I just want to make sure nobody gets into trouble.

Is the model you converted from free for any use, or did you get permission from the original author to convert it for use with RealFlight? [http://12.156.2.54/forums/showthread.php?t=11723]

Was the original mesh in 3DStudio?

How did you convert it?

G3 doesn't understand the plane's orientation very well.

It was driving me nuts trying to figure out how to set the CG and other parameters.

When I realized that G3 saw it "sideways" it all clicked and made sense.

Once I started manually adjusting component weights everything fell into place and it started flying like it should.

Lotsa fun.
Great model.

hi
i downloaded the file again and it still says this ???????
PLANE FILE REFERS TO MISSING COMPONENT FRAME '`CS_RW AND '`CS_LW ???

ok as far as that 10% gos make the size on it to 125 to 150 and it will takeoff good use the knobe to the right to get in the air than back the other way
the 10% is to big your wheel drops down and kills it.......so try the 125 to 150
