The tuning continues

I did a little more testing with the Hyper TT yesterday.

I lengthened the wheelbase another mm by moving the front arms (top and bottom) forward another mm which helped the stability and overall ease of driving.  I also am running a little bit of toe out which helps immensely in the small, tight U-turns.

Not sure on how many degrees of toe out, it was 1/4 turn of the turnbuckles from 0.  I try not to use toe out if I can at all avoid it, but I don't think you can on this truck.  It just doesn't have enough steering lock and Ackermann.

I also dropped ride height to 27mm front and rear (from 28mm).

I'll be testing some diff oil changes next time out.  7k seems too thin in the center, I'm going to try 40k and then go up or down from there if necessary.  I'm also thinking of upping the shock oil weight -- currently at Associated oil 32.5F/27.5R.
