DONT SELL IT.take the time to learn about your RC. when you first get ready to run your rc car truck boat plane.be sure your rc can read good.walk about a 100 feet away from your rc and pull out the ant.1 clicl up or out. turn on the radio!move the arms up down left right.have a friend see that all is doing good and that nothing is jumping at the servos.then be sure that your air jet is at 2 1/2 turns out.then start the motor.if it runs real bad turn in the air a little at a time but not to much.to brake it in good.you may use 2 plugs to do this but its to do it right.after 4 to 6 tanks clean the air fliter if dirty with rc gas or soap and water.not real gas,it must have rc gas in it.if you use real car gas it will hert the motor.the gas from the filter will go in the card to the motor.the gas must have oil in it. if the truck is running to fastturn in th trim to te gas and slow down the motor.untell its right.but not to much it will work the brake too.try that and see how it does ok..let me know if you need motr help ok
