Congratulations ScottyP. I also think that itīs best value for the money.
Itīs has the 54018 "single" slipper clutch, not the double slipper (#54061)
Btw, The 511 also comes with the new spring, but the standard "single" slipper.
Brushless motor is not included in the DB01R kit.
Only options you might want to buy are the 501X outdrives ($30) and titanium screw set ($30). Of course a body shell as well.
I have ordered one + a Durga bodyshell.
Will not replace my 511, but really look forward to try the DB01 chassi.
With the new drive belts it will need very little maintenance.
