Re: [Titanaircraft] Re: Fin on front wheel pant

Hugh,

We've had both, and the spring steering is by far superior to any direct steering, even without a wheelpant since there are no nosewheel to rudder alignment issues that change with a crosswind. There is also no hunting that is usually experienced with any sensitive direct steering. The semi-free castoring (spring steering) allows the airplane to track like a missle down the runway without ever having the yaw jerk when the nose lifts off, particuarly with any crosswind. It is also not super critical on yaw in flight like the direct steering. I just delivered a 2S last Saturday, which took 3 hours, 10 minutes. This 2S had a wheelpant with the fin cut off, and direct steering. It the most yaw-critial Tornado I had flown to date, and no where near as pleasant to fly as our 2S with spring steering and the fin. It was so yaw sensitive, it was frustraiting the new owner that I had put up front to fly it after arriving there. I have a feeling that may be changed before next summer.

One cool suprise I had was to fly right seat in his Pilatus PC-12 for the return trip. I flew it for a while until we punched the auto-pilot so the pilot and I could do a little gabbing during the flight, which was barely 1 hour and 5 minutes, with a head wind. I know we've got a commercial jet pilot or two in the group, but for someone within my means, it's an experience I'll not soon forget.

Well, I learned something!

The person I bought my plane from told me that he tried both direct
steering and spring steering, and that the direct steering was much
better.

And my nose wheel pant has a fin on it.

I've always noticed that the airplane is sensitive in yaw, but I've
learned to keep the ball centered anyway.

It seems that with the direct steering, I shouldn't have a fin!

Anyone have comments on direct vs spring steering?
