Clunk line in main tank could be the issue.

I've had that happen twice in flight. The small diameter lines they supply with the tanks split quite easily. The lines are also very thin walled.

It is now a replacement item that I change often as preventive maintenance. Fuel line that is small and flexible is also hard to find. I bought 20 feet when I did find it, just to have a good supply. The stuff I bought is a little thicker, but still flexible. None have split since.

I enjoy doing autorotations, but much prefer them on MY terms!..LOL

Good stuff, I use it in all my tanks, I discard the stock clunk line even with brand new kits, well I dont discard it, it makes a nice shield for your antenna wire where it goes around plastic or carbon edges.

how would the regular fuel line you use work.I tried it cause its all i had at the time it seems to work ok just wanted to make sure. Messing with the throttle curves some now. I have the jr8103h with digital trim except throttle. The raptor 30 has a os 37 with revolution muffler and thunder tiger blades What are yall runnung i know it depends alot on set up as everyone is probably different.

Regular fuel line will work....as long as you are just hovering or gently flying around. You will have problems if the clunk needs to move during aerobatics, 3-D or any extreme maneuver where the clunk has to move to stay in the fuel supply.

The Hayes Neoprene Clunk Line is the stuff to use. Keep in mind that it does expand about a 1/4" when it gets soaked with fuel. Something else that will greatly extend the life of clunk lines is pumping out all unused fuel from the fuel tank when done flying. The fuel will last much longer back in the jug/can and leaving the clunk line soaking in fuel for a week or more is only going to shorten it's life considerably. Cheap insurance for like a buck or two a foot.

I have Hayes Clunk lines in all my machines and one is going on 3 years and just checked it a month ago and is in great shape.

Don't forget to do the header tank too.

A header tank will give you about another 2 minutes maybe.

But that's not the main point. It is there to reduce foaming fuel (from vibration) reaching the carb and upsetting the mixture or causing a flame-out.

I never fly out my header tank unless it is the last flight of the day.

The tank connection is simple, connect the original carb line to the top outlet of the header. The header also has its own clunk line that is then connected to the carb. Look Here

Actually its the nitric acid in the exhaust gas that causes the fuel line in the tank to break down. Case in point, the fuel line in your jug that you are pumping it back into is probably years old and doesn't degrade Leaving the tank full will actually extend the life of the clunk line.

This is interesting, I have flown planes for over 17 years and never had a problem with fuel lines degrading. However, I only use 5% nitro in my planes. Is it the higher nitro content that is so hard on heli lines?

Having said all that, I just built my first heli, Raptor 50 Titan. Changed the fuel line. Well, why take chances, right? [sm=lol.gif]

I have no idea about causes but after flying some cool (for me) flips, rolls, loops etc my heli died about 1 foot in the air just as I landed. Clunk hadn't just split, it had completely broken off altogether.
Talk about lucky.
Clunk line was at least 6 years old but now I'll change it at least every two years.
