As we don't really have a 12 class race here, it doesn't really matter to me if it's legal to race or not. What I really want is extend runtime, less wear on tire, to save me some time on charging and $ on practics.

If 1s 5.5R is about the same speed with 4c 19T but with longer runtime, wasn't it cool?

Jason please make sure you post your 1s LiPo setting in DB12R thread, save me sometime to fingerout setting to begin
