This may be a stupid question, but I'm confused a little.

I race RC cars, and I use a little pump that pumps the fuel from the tank to the engine. My heli doesn't have one of these, and I haven't tried to start it up yet. This weekend will be the first time I start it, and I was wondering if just using the starter automatically pumps the fuel in or do I need to do something else.

Use your pump, if there is not a separate fueling line just pull the line at the carb and fill there. If you've got anyone locally experienced get them to help you with this. If this is a NEW heli it will need proper breaking in of the engine. Also be positive that you have the throttle correct as to not make your first start a hot start, bad beginning for the motor and not much fun for you or the clutch.

If I throw a stick, will you leave?

Well, I'm not having a problem getting the fuel into the tank. I have an electric pump that does that. The question that I am having is how to get the fuel from the tank to the carb. On RC cars, there is a little pinch pump thing that does this, and I was wondering how I do this on a heli.

a pump isn't normally required. Add a pressure line to the vent on the main tank to the muffler. This will give you a little positive pressure on the fuel system.

When you spin the heli over and the throttle is open enough to draw fuel the suction will draw fuel in the motor.

DrDan,

You don't need a pump. The fuel will be sucked into the carb when you start the engine.

The heli's use the pressure from the exhaust to push the fuel up to the carby.
So when you have the starter motor running I just quickly place one of my fingers over the end of the exhaust extention and that pressurizes the tank.
Don't leave your finger there for to long because you may flood the motor.
I only do this the first time after the heli has been sitting for a day or so.
