Lee,
Thank you for the tips! I bought some tiny (1mm x 2mm) magnets to supplement the tiller magnet on the Mustang. Three of them did the trick, and it now tracks the 11" curves perfectly. Also tried the tape you recommended - it is very slippy as stated & noticeably reduced tiller friction. Mustang traction on the hill is better but still poor; I plan to add a little back end weight to help it out. It has plenty of power, but no grip.
Unrelated question: Have you tried painting your tillers the color of your road? I was thinking of doing that to mine to better camouflage them.
All,
I rearranged my "city" to optimize viewing of the towers/interiors when they are lit... and to best line them up new roadways laid out in a logical manner
The AutomotionFX roads won't be the only ones in the city - I have other side roads (and portions of main roads) that complete the city look but won't be "active". In order to blend them seamlessly, I bought some plain 1/8" MDF to cut my own sections of "dumb" (as in not wired) roads and parking lots:
Here's an example of a dumb road - the main drag through downtown (darker MDF). Note how it will intersect cleanly with the FX roads (lighter MDF)
...and another dumb road to the right of the gas station
...and some dumb sections of main road (darker MDF) are also visible in the lower left of this picture - both as components of the main entrance to town and as a strip for parking. As of this picture, I have removed the majority of the buildings so that I can build their bases & sidewalks. Since the roads are a uniform 1/8" thickness, I'll make the sidewalks all 1/4" tall for scale 1/8" (6 inch) curbs. While I'm fabricating bases and sidewalks, I'll also start spackling and painting the roads. Cat shown for scale.
Also, I did some doodling and settled on a design for the tunnel ramp entrance. I decided to go with a mid-century look. Below you can see the cover "skeleton" glued together. I plan to fill the gaps with bondo & sand for uniform curves across the top.
Here's a test fit of the tunnel entrance over the ramp. Back of the ramp (behind this cover) will be covered by a removable panel:
