Building a Solar Powered R/C car

Step 3 Building the front wheel assemblies

Build the front A-Arms to the directions that Associated provides. In most cases if using a donor RC10L the assembly is already built as it was for me.

Now comes the tricky part connecting the wheel assemblies to the steering servo. Many ways to accomplish this, and imagination will help. My final design used piano wire and Du Bro EZ servo connects and wheel collars.

I then took a piece of piano wire that I sharpened and poked a tunnel through the foam from the steering wheel to the servo horn. I expanded the hole a little more with a dowel rod. This tunnel is for the Linkage. I measured the distance from the servo center to connecting point on the wheel and then added a few extra inches. I bent a 1/2" 'L' at the end of the wire. I inserted the wire into the tunnel with the 'L' being at the servo. The 'L' is connected to the servo horn and held in place with a wheel collar.

Center the servo horn! Point the Wheels straight.

Using a marker, I marked off the excess piano wire that needed to be trimmed off but also left a 1/2" extra for error. Remove the linkage, trim, then reinstall.
