Excellent! Lifts-off at the end of the runway on USAF Museum photofield!

Good job!

I uh...well...was having some fun and uh...

Next up...

A much heavier version with higher wing loading.

This lifts off at about 124mph but needs a bit of a hand...

To take off...

Knob to the extreme right, THROTTLE TRIM FULL UP, nose down slightly.

Once the plane hits 110mph press the nose down then pull up around 120.

The collision mesh problem is at work here. In effect you must "unstick" the plane from the runway.

Once the nose is up, it lifts off gracefully.

Landings are better, but require faster approach speeds.

Remember to bring the throttle trim ALL THE WAY back down prior to landing.

Opjose is there anything i can do with the collision mesh to help the plane get off easier?(lower it maybe to lift the nose abit).

Lifting the nose a bit definitely does the job.

The angle of incidence given the surface the plane is on, makes ALL of the difference.

It might not be quite scale to do this, but it may be advisable, and hardly noticible.

Could you try?

Love the plane... I'm trying to get it to produce those beautiful nose high landings, but I'm overcompensating for the takeoff problem.

Very nice job Opjose, the Concorde flys much more realistic know. I also think a longer foward gear could help on the takeoff problem.

About better AOA for landings maybe palying with the CG or airfoils might help.

I still feel it floats a bit too much.

Keep up the good work guys...

Hi Inky00.

This did not seem to help, and may have made matters a bit worst.

Please see this thread

http://www.knifeedge.com/forums/showthread.php?t=12923

In it he describes a change that he made to the mesh that did indeed improve things.

I haven't worked with this stuff in 3DStudio yet so I'm of little help here, but I've observed the end result vis-a-vis the physics modeling.

His fix did improve things for his model though.

Re: Floaty

Yeah I'm aware of this, the wing loading is quite low to lessen the "stickyness effect".

On the last posted model it's as if that front wheel is stuck in a slot.

This did not help.

I posted a question about this in the designer's corner.

On rare occasion I find that once you've gotten the plane airborne, it will take off correctly on a subsequent try.

This is not consistent however and very confusing.

Could you please check out this thread?

We had the same problem with the VelocityXL and it has been cured.

Inky00:

The plane now does not stick... but there is a "ahem" slight problem.

Try this.

Load the Concorde you just posted and retract the landing gear with the plane on the ground....

You'll see what I mean.

Hey Opjose,
I have now put collision meshes on the entire aircraft so this should solve the problems of the wheels sticking and the plane sinking,please check it out

I'll check it out.

If this fixes everthing (which I'm sure it will) then the first (or entire) thread should be reposted.

inky00,
Your Concorde is a joy to fly!

I'm glad it's not a fighter jet - you have to plan for a long final approach.

I love it - thanks!

This plane still seems to be stuck to the ground??? I made this one a hand lauch .You can either throttle up and shoot into the air, Or you can just drop the plane and then it takes off fine..So it almost seems like the sticky effect has something to do with the runway..
