I just got mine and it seems a bit slower compared to my other recent Slot It purchases. Probably due to the fact that this is now a true 21.5K motor and not the earlier 21.5Ks than ran at 23K... and the fact that I've got 1403s on it - I think 1402s would be the better choice? Still, it looks the business. Now to secure the rear wing.
Well done, Slot It!
