Default RE: Skymaster F-15 Steering Stability

Guys-

Success!!
I made a couple of changes. First, I found out why the steering cables were loosing up. The arms that the steering cables were attached to at the nose gear strut were actually bending towards the servo and creating slack in the steering cables. I simply lock-wired those arms together on the back side of the strut to oppose the force created by the steering cables. I'm assuming the force on these pins was created when the gear slammed to the extended position. Next, I set the main gear to a slight toe-OUT as I figured a toe-out position would try to counter act further tipping if the plane tipped onto one or the other main gear. Finally, I reduced the low-rate steering travel to almost a 1/3 of where it was when I initially started taxi testing.
With all these changes the taxing and maiden flight was a success! No issues on the take off roll or landing.

Thanks for all the help.
Regards,
Mike
