I used to use header tanks all the time. But not because I had fuel problems, but more to avoid them. For the last 2 years I have flown without header tanks> Had my first flame out the other week, due to hard 3D on 1/5th of a tank. I landed and started again, and was able to hover the whole tank out, even mild 3D, just to see if I could re create the problem. I couldn't.

If you have flame out problems put a header tank on. If not, don't fix what ain't broke.

One other point. Curtis never used a header tank....

I removed my header tank from Sceadu OS50 about 6 months ago.
Didn't have any problems before.
Haven't had any problems since.

I'm going to leave it off.
Less complicated.
Looks cleaner
Makes me inclined to check the main tank tube and clunk more often.

Then when the main is empty and you are drawing completely from the header tank - she will change again depending on where the header tank is in relation to carb height.
I kind of like it when this happens. I can hear the change in the engine performance and know my main tank is empty so its time to land.

I agree with anyone who says it is not necessary including Jerry. The header tank is just a wide section of the fuel line. It does nothing to help fuel feed consistancy and only marginally helps with foaming. If you have so much vibration that it causes that much foaming you need to rebalance you blades or check the run out of your shafts. The header tank is a crutch that can actually add to your problems by giving you one more thing to worry about and one more thing to fail. (In my opinion )

I disagree with this. In my case it is very useful. Not in terms of fuel flow but in terms of visibility. The tank in my heli (Voyager 50) is buried in the canopy and not visible. If I didn't have the header tank I would have to land and stop my blades just to check and see how much fuel I have left.

I could time it (and I have) but different types of flying will use more or less fuel. With the header I can bring the heli to a hover and check the fuel in the header to know whether it's time to land or not.

IN TERMS OF VISIBILITY IT IS VERY USEFUL. Where you can not see your fuel tank you should have a good idea of how long you can fly on a tank of gas. For this mostly it is useful.

has been said that if clunk fails in main tank then a header is a saver as it stays full.......Well i think that you would be very lucky to notice the header going down in the middle of your flight so resulting in probable crash anyway.....also is said that if clunk goes in header its ok because it stays full of fuel, this is of coarse true and has happened.

If you do use one tho, make sure it is on same level as main tank as i believe the height will affect the mixture....

If you mount the header off center of the main tank then you will get a warning of problems.
I have mine mounted well above the carb and main tank, this causes the mixture to be lean inverted and very rich upright only when running off of the header tank. When this happens I know that there is no fuel comming from the main tank for whatever reason, so land NOW.

While running off of the main tank the header is nothing more than a fat spot in the fuel line, its location does not affect mixture till you are running off of the header tank.
