Default Spring Air 302 nose gear steering

Greetings,

I am installing my Spring Air 302 retracts and have been looking at the steering hook up on the nose gear. Is the best way to connect this to a servo to use a pull-pull? Use two servos? I think that a single cable may prove unworthy when retracted, twisting the nose wheel on it's way up. Any advice?

Kaos,

I made the nose wheel in my F4 work, but I'm not totally pleased with the installation. If no one comes up with any better suggestions, I'll send you a post on what I did. I'll be out of town Friday - Sunday, so it will be Monday till I can get back to you.

Default Steering Setup

Pull-Pull is the way to go on the steering linkage. Instead of running two individual cables between the servo arm and steering tiller arm I just made a continuous loop system.

The strut will have to have a self centering device so that when the gear retracts and the cables slack, the strut will remain centered. You also need to have a post anchored to the side of the fuse in the cable area so that you can attach rubber bands or small springs stretched between the post and the cables; so that when the cables go slack the rubber bands or springs will pull the cables back out of the way. This will make sure they don't become entangled in the gear during the cycle.

Here you can see how the cable is looped through the tiller arm.

Default steering linkage

This cable steering setup has never failed me yet. I have used this method many times, simple and easy to adjust for wear and tear.

Hey Kaos1, see your down in Charles Town. One of my customers is there. Where do you guys fly at? Since I travel the mid-atlantic and northeast, I'm always looking to see what and where people are flying. You can email me if you like. Always looking to meet other pilot as well!
