I don’t understand the reasoning behind opening the rules to an additional motor.
Motors for the Slot.it, Thunderslot, and NSR series are all readily available and cost only $18. The difference is not that significant from a $9 Pirana motor in the overall price of a car. On top of that, it adds an additional layer of complication for the competitors by giving them one more choice to make when selecting a motor for a stock series. It’s easier for everyone when the rules allow one option as opposed to multiple motor choices. With the multiple motor choice rule, a competitor could potentially spend more money as they purchase a Pirana motor on top of a stock motor in a quest for the best motor. I think it’s easier for all members – new and old – to have the rules be as simple and easy to follow as possible. No need to complicate things.
I am all for allowing the multiple motors options in an open series where many of the parts are open to a competitor.
