Plane bouncing on takeoff

[Branjoman]

Hello, I am having a small problem with a plane I have built. For some reason, when the plane is trying to take off and pulling up, the plane begins to bounce on it's front wheels (the back wheel kicks up), which hinders the plane taking off. Is there a way to rectify this problem.

EDIT: So, I set the front landing gear spring and damper to 0.5, and also set the tail gear spring and damper to 2, and the problem was fixed! Thanks for the help guys.

If you can give a craft file and a mod list I could take a look. This is either a collider or design issue, if the craft doesn't have enough lift initially to get off the ground it will bounce a bit before taking off.

This is most likely the standard jitterbugging problem. Yours is a very light plane, and the standard suspension settings are for a medium heavy plane -- so your suspension is too stiff. That, combined with a Unity joint bug, makes your plane bounce.

So the answer is: in the SPH, click on your front gear, set the spring to .5 and set the damper to .5 -- then save it and give it another shot at launching.

Besides the good advice others have given, I would also be very careful with that little tailwheel.  Those and the fixed main gear are NOTORIOUSLY bouncy.  Maybe ;making the tailwheel less stiff would help, too.

But regardless of that, try very hard to let the plane fly itself off the ground without you applying any controls.  If you pull up and cause the tailwheel etiher to hit the ground if it was already up or push it into the ground if it was still in contact, you will create bounciness.  With a tail-dragger, the plane is already angled up just sitting on its wheels so once the speed is high enough, it should just float up by itself.  Let it get good and clear of the ground before applying any control to it.
