Kyosho Caliber 30 & 60 - Concept - Nexus > header tank Concept 30

I would like to get a header tank for my concept 30. Any ideas on which one and how to mount it?

Sure it is.

A Sullivan two ounce round tank will fit very nicely on the lower frame member, just ahead of the rear strut mount and under the needle valve. Secure it with a couple of tie wraps.

The Hayes tank with bracket will work equally well, but will require a bit of thought and fitting to not interfere with starting cone access.

I put the extended-capacity main tank in mine when I resurrected it, but only because it was in the box of goodies I bought from a fellow- not because I thought I needed it.

Why do you want a header tank? Not criticising, just curious...

I've seen one setup where the tank was mounted behind the rear landing gear strut on a plywood plate. This puts the tank well below the carb level, however, and I didn't really like that.

I think I'm going to make an aluminum bracket that bolts to the frame right below the engine, and put the tank there. It's about the only place I can find that I would be able to fit it in.

If anyone else has put a header tank on a Concept, I'd like to hear of the mounting method as well.

I want to get the tank mainly to see how much fuel I have left.( I tend to forget to check it, and I figure if it is plain wiew I will notice it better)

Thanks for the help, I think I will try the sullivan tank!

Here is a picture of where I put mine when I did some major upgrades and cleaning. It now looks new for a little while.

It is a zeal concept sr-x

Note that I need to put a extention on the carb adjustment. This keeps the fuel in line with the carb and I can also see when it is 1/2 empty.

That looks good, Did you have to put spacers on the mounting bracket to clear tthe fan shroud?

I used a set that I got from rick's Heli. It has a built in spacer that clears the fan shroud.

I was looking at that , but wasn't sure it would clear. Now I know. Thanks.

I have a 1oz round tank zip-tied to the low frame member, just as Steve C described. Works great. Putting the header below the carb doesn't cause any problems at all unless you run the main tank completely dry. So, I don't do that.

Just for grins I zip-tied the tank to the frames just aft of the main tank, and mounted it vertically to get it up as high as possible. It ran the same (unless the main tank was completely drained of course), which confirmed what I always suspected: the header tank is just a wide spot in the fuel line, it doesnt' matter where you put it. (Unless the main tank runs dry - but I don't do that.)

I returned the tank to the lower position because it's nicely out of the way there.

<<...just a wide spot in the fuel line...>>

I've always suspected that, Nate. However, on my TSKs, due to the tank configuration the header was mounted on the side of the main tank itself; and it did seem to make a difference in the mid-range mixture when the elevation of the tank, compared to the inlet nipple of the carb, was moved.

But that's the only time I have ever noticed a difference. I don't even use header tanks any more; they are really only necessary for 3D pilots as a bubble trap. Yeah, the y make it easy to check fuel level on ships with front-mounted tanks; but every decent heli radio I've ever seen comes with a timer...

I don't have a timer on my radio. I've heard if you mount the tank so that the outlet to the carb is even with(or slighly below) the spray bar you can safely empty the main tank and still run on the head tank. Is this true?

Yes, it's true. But you can also mount the header tank away from the centerline to get the engine to run differently when the main tank empties.

When the exhaust sound changes, it's time to land. It's like a timer, only better, because it's based on the actual fuel level, rather than on a stopwatch that has no idea if you've been guzzling fuel doing funnels at full throttle or sipping fuel doing autorotations.

Oops; sorry.

So, do what a lot of plankers do; buy a five-dollar kitchen timer and velcro it to your transmitter...

All in fun, guy; not dissing you. Seriously, the engine has no idea where the fuel is coming from. As long as the supply from which the engine is drawing, be it a header tank, main tank, whatever, is not radically above or below the carburetor, it will feed the engine fine. The mixture may indeed be affected, and as you will learn, mixture plays a much bigger role with helicopters than it does with fixed wing. But the engine will still run, naturally assuming it is properly adjusted.

So to answer your question is, yes, the engine will continue to feed from the header after the main tank has run dry.

Again, there are only two real reasons to fit an auxillary (header, saddle, whatever you want to call it) tank. The first is for additional fuel capacity, if needed. The second is as a bubble trap for hard 3D, to prevent an unexpected flame-out if the main tank clunk should flop out of the fuel supply as it diminishes during a flight.

If your engine is not drawing fuel properly from the stock tank, an auxillary tank will NOT cure whatever the problem is.

No offense taken. I like my radio because its simple. I won't be ready for 3D for a while. I just like the ability to see when I am running out of fuel. Thanks for the help.

You're right; make that THREE reasons for fitting a header tank.

How soon we forget. Thinking about this, I suddenly remembered that I fitted a header tank on my first Concept for the same reason; and the Kyosho pot radio I was using didn't have a timer, either...
