Looks like Dan from kershaw Design reads my thread
Here's a new description of his chassis. Still the same picture but a different description.
''-
Now with receiver box mouting tabs, improved tolerances and clearance,
stiffer chassis braces and all for $10 less!
-
Only 0.5 oz heavier than the stock plastic E-Revo chassis and worlds stiffer.''
I paid $10 too much
