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

I too tried the spring steering many years back when I added wheel pants to
my Tornado S model. I had added the large fin to the nose wheel pant and
when flying it with the direct steering still intact, the adverse yaw from
the new front rudder was terrible. I quickly ordered the spring steering
components, installed them, then test flew once again. Well, the adverse
yaw was corrected, but I absolutely couldn't stand the poor ground control I
now had to deal with. I knew I was going to make a change the day I went to
a fly-in with my wife while during a group take-off I had to drop one wheel
off the runway to make room for another plane. There was a slight slope in
the grass, and wouldn't you know it, I couldn't get that bird to turn left
to save my life.

I was so used to the impressive tight maneuvering on grass or pavement with
the direct steering that the spring steering just had to go. I converted
back to direct steering, then cut the fin down to about 3" long. Aah...back
to my kind of flying.

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?
