Default Toe-in, Toe-out, or straight on main landing gear?

What is the preferred setup for main gear? Sloght toe-in or slight toe-out, or straight?

Toe IN helps on payment. About 2 degrees. On grass, doesnt mattter as much, but NEVER toe out.
Cheers

Hi

Actually a little toe-out will help the plane in ground handling. If you want it to roll straight, put a little toe-out.

An airplane is not a car in ground handling. It's a 3 wheel vehicle. Toe-out improves high speed stability, reducing responsiveness in steering.

Toe in and toe out are tuned in the car front wheels. We do it on the rears and have only a front wheel. Plus, there is no traction on the wheels.

From my experience, toe-out promotes less wobbling during take off and more stable in high speed.

Do your testing and have fun

+1 let's be real guys, these models are real airplanes. As a Licensed A&P full scale mechanic, I can tell you that the main gear on all full scale stuff is setup toe in. ' Nuff said.

I think you have it backwards. Toe-out makes it harder to control and less stable.

Most instruction manuals I've read recommend toe-in , but could be different in Portugal.......

This discussion has not a right or wrong answer.
My SM Cougar was a pita during ground handling until Peter Goldsmith asked me to put some toe-out .... unbelievable difference !!!
I guess toe-out has less tendency to bite when the airplane starts to turn. It's like moving the steering wheel when slipping.
But whatever works best for each airframe would be the proper choice.
And I guess that it has nothing to do with Portugal either !

Also, a Powerbox igyro-1e dedicated to the nose wheel wipes out any toe influence .

I use a builder’s square and make mine straight with zero toe. To each his own.

Oh my h*ll, talk about someone who does not understand the issue at hand with gyros.....

In the first place, no nosewheel actions by a flight gyro will convert a poor main gear setup for tracking on takeoff or landing but landing is the biggy. Second, MOST issues with tracking involve the main gear brakes on landing. An iGyro is NOT going to be able to counteract that component no matter how many course corrections are sent to the nose wheel. That is why the new landing gear gyros like the Electron G200 can moderate braking on each wheel during roll out with a gyro assist function.

It was an attempt at humor, no offense intended I'm sure.

No sense of humor .....omg !
But on a serious note - some manual's & their translations can be confusing when the verb is before the noun & quite funny at times

Just as a matter of interest do tell us what aircraft YOU are licensed on !

Forget toe-in and toe-out. Just use Loctite, some expo and a gyro.
