This isn't much of a test, but I had the car out last night on the street, just setting the 2 speed shift point. The car has A LOT of stearing! It comes off the line very quick too. Easy to recover from a spin (just had to try), and it the rear is planted, I took it to the end of the road, where its sandy and turned around, the car tracked very well.
From the build, I had to back the shift point adjustment screws out 3 1/2 turns.
I only ran 1/2 tank, but I can't wait to get this on the track!
