Please help with Airbreake

[ynoz]

Hi please some help

I've been trying to combine an intake and airbreake in a single fuselage part... and while the air intake works as intended, i have all sorts of problems with the airbrake

please please HELP

here the pic and code

}

}

}

}

NO 1 ? please help

my main problem is that when it is deployed it doesnt generate Drag, but undeployed it does generate the drag as intended. so something is backwards

Does it start deployed or retracted? I get the idea that it should be starting retracted.

It starts retracted....

lets say that i have a drag coef. of 10 at start (retracted). but when i deploy it my drag coef goes to around 7.5 - 8. so... i suspect theres something wrong with my axis... but i cant figure whats the problem, since i have x+ right, z+ foward and y+ up or "lift".

Are the local axis all lined up? The local axis is what determines the pivoting for the wings, not the global axis.
