Quicker isn't always faster
 

Currently running 13.5 boosted but getting beat by 17.5 blinky, just seems like on our small tracks your mistakes are exaggerated by extra power.
Going to first drop the boost but will be buying a 17.5, if you can't beat em!!!

Question is what motors from experience of 17.5 blinky do people recommend?

Quicker is always faster, over powered and out of control is slower than smooth and in control..... Just run it in blinky

Cheers Mark that was my plan but if I'm to run in a 17.5 blinky event what do people use and good or bad experiences

Vampire motor is good. Lots of others seems decent too. Worst I have used is the HPI Flux Pro.
