HI GUYS I JUST GOT MY HELLFIRE A COUPLE DAYS AGO AND I STARTED TO BREAK IT IN AND ON THE FIRST TANK WHERE YOU LET IT IDLE ON A BLOCK OR WHATEVER IT WOULD IDLE GOOD FOR A FEW MINS THEN IT WOULD START REVING REALLY HIGH SO I SHUT IT OFF SO I DIDNT WRECK ANYTHING AND I DONT KNOW WHY IT DOES THAT AND I WOULD LIKE TO FING OUT IF SOME OF YOU GUYS HAD THE SAME PROBLEM AND TELL ME WHAT I COULD DO TO FIX THAT PROBLEM LIKE MESSING WITH THE IDLE SCREW OR WHAT AND THERE WASNT MUCH SMOKE OR FUEL COMING OUT OF THE PIPE LIKE ITS SUPPOSE TO EITHER. I HAVE BROKEN IN THREE OTHER NITRO ENGINES AND HAVE NEVER HAD A PROBLEM LIKE THIS AND I DONT KNOW WHAT I NEED TO DO TO CORRECT IT

Well its not that bad, first make sure your settings on your high and lowend are right, and on your high end, I turn them about a 1/4 to 1/2 turn counter clockwise (righer) when breaking them in, Now when you go to start it make sure your controler and reciever are on!! and you should be able to control the idle by the throdle trim! then go for there!

ok i wil try that when its not raining out like it is now but thanks for the help

whoops sorry about the caps didnt even notice it lol
