joeye they have told u that there is not problem for blinky it will run any motor
there was a hold up on stock1 softwear and it didnt surport 11.5-21.5t for boosted (which have tried in 13.5t and is fast so dont know what the meant by not ready) but the new release now cover 4.0-21.5t boosted class


hi xenolance i also run a r with 13.5t boosted and i have to much drag brake even with it off it might just be the motor u have eg gm2012 x12 motors i find nearly stop to a halt when letting off the throttle but fit my orca2 motor and it just rolls on
so if u have a different brand try and see if there is a change
