its the sound of boost kicking in don't free rev the motor for very long though, as you'll damage it.

Yes, not all the x12's are like this but we have 2 at our track that just sound like a vacumn when they spool up but run good and don't over heat. We have noticed that the one's that are loud are the first batch, the one's that were bought when they first came out.

if it squeals it may be the sensor use the on board checker by rotating the drive train and watch 5,6,7 led they will flicker very dimly,did it cog as well
