With the timing advances should they be called 10.5 and 17.5 any ESC.
In Europe they are thinking about calling Mod '10.5' so in effect we are already there. Just re-label the classes.
Windsor have adopted 12th scale with 10.5 limit, most weeks it one of the biggest classes.
Most people are happy to have the latest and greatest it keep the technology moving forward how else would brushless and time advance motors arrive on the market.
We have to think about how it will effect clubs here, without the clubs there is no racing, remove there biggest class 17.5 and they move to a club which still races 17.5 with tekin or lrp..
Stock racing should replace 540 maybe even run 19.5t as stock motor and speed combo, have 2 Manufactures bid for the supply for a years contract? - Pass on the saves to new starts / people who want a controlled race format leave it to the driving and gearing. A sealed unit can be easy to control.
Would this class take off?
