huh? all bigscale models i know of use 10mm pinions this ist the size of the clutch used on zenoahs and similar engines.
the plettenberg bolido is explicitly a car motor. and the big schulze escs do very well in many big scale conversions. those escs and motors are sure intended to be used in car models. of course the "market" may not be that big yet. and to be honest i am pretty sure it will stay much smaller than the 8th scale market even after the entry of the castle system for different reasons. but we will see.
i know you have 8mm pinions. thats nice.
however there was imo no need at all to go for another standard.
10mm would simply have been compatible to the pinions etc already existing.
anyway now the things are set and we will adapt to the realities. no big deal.
