I'm really liking WGT. Have only been driving about 6 months. Started with Tamiya F1s now have a Serpent S100.
Outdoor track with 60 metre straight so big track. No limit for motor so I've got a Speed Passion 6.5T and LRP SXX Esc combo with 2 cell LIPO.
Now up to about 20 packs running and still 1 set of tyres.
Diff balls and spurs don't last long. Not the spur teeth, the holes for the balls get elongated (assume from slipping?) but they're cheap.
