Hi Gordy,
unsure if this brushless limit has been decided or not yet (guidelines above still unclear). However, with the advent of the CE version of the Mardave, it is now clear that the standard chassis restriction of 17.5 brushless - 20turn brushed no longer applies. The new chassis can clearly handle more power than the previous aluminium slab. I would suggest that we keep the class open to 13.5 brushless / 19 turn brushed as you still require good driving skills to keep these cars on the track with that level of performance. I for one will be sticking to the Saturn 20T as this coupled with a decent battery/esc is quick enough to compete with the NKOTB

(I hope so when the new battery arrives). As this is still a budget class of racing, I would not want individuals to go out and spend more money on a brushless motor that is only suitable to one class of racing. 13.5T brushless motors can be used in TC's as well so are interchangeable between classes. I agree that blinky mode (non turbo/advanced timing settings) should be set to factory.
On another point, the standard of racing in the Mardave class has improved significantly during recent weeks. Popularity seems to be increasing week on week. I have been saying for years this is the best class for indoor racing. Now if only everyone had one....
