First , check the glow, make sure the glow still work, otherwise replace it. (high chances its the glow that have blown)

Then check the fuel supply, pull out the tube to the carb and pressure your fuel tank and see if fuel arrive.

Ensure your high end needle is set to a rich setting.

If the above didn't work, go look for further help, experience guys will be able to pin point the fault when come face to face with the engine.

Good luck..!!

Usually.. 4 turns is too much...most engine runs between 2-3 turns..aircraft engine runs `1-2 turns and heli go as low is 3/4 turn..

Good question...!! the answer might be quite complex..hee...hee...

This is what I would do,

1) Unplug the steering push rod join to the servo push it to both end and see if there is any obstruction and manully move them with your hands to make sure it reaches both end point correctly.

2) Check your servo throw to both ends and make sure they move to both end correctly.

3) Center the servo throw and the steering push rod and clip it back on, your steering might not be straight at this point.

4) Adjust the other push rod that connect the individual arms to make the wheels straight.

You should get equal throw both side by now.

5) Use End Point Adjustment to max the throw position or reduce binding.

Good luck..!

i've done all the step tht had mention, seems like the left arm stuck in somewhere....when turning too much on left the servo seems like wanted to break free.....right side able to turn at least 45 degree but on the left on 20-25......is tht suppose to be? or is both at 45 degree?
