when is a gyro used on a plane?

When they turn it into a helicopter...[sm=tongue_smile.gif]
When you need extra weight for balancing.....[sm=spinnyeyes.gif]
No, really I have no idea...I've never heard of that.. I could use it as a good RC trivia question if its true. You learn something new everyday...
Does anyone know?

Actually..I think that is exactly it...The 3D guys and their hovering stuff I believe...

Have Fun...

When you have marginal rudder authority and need a helping hand keeping it flying straight. I know some scale models use them and some early discus launch gliders used them for straight launches. Don't know where else they might be.

I recall years back they did some experimenting with unstable cg positions and gyro pitch control. Can't remember which mag, however.

I've seen them used in some of those exact-scale, $30,000 turbine jets. Like Mark said, sometimes a scale tail outline isn't adequate for a model, although it may be more than enough area on the full size plane. The Hawker Hurricane is an example of a scale plane where model designers will often increase the tail area (or use a gyro).

I think they are illegal for both pattern and IMAC events. So no reason to use them in practice. The only time I know of is for distance record planes, which may also include GPS control.

Yup..Your right...No Gyros allowed...Thanks

Thanks for all the input fellow flyers! [sm=thumbs_up.gif]
