Hi all,

I fly a rappy 50 with OS 50 for a few months now and it flies great,but the last few tanks i noticed that when the maintank gets half empty the engine goes leaner,and the headertank is going empty.

I thought the fuel tubing inside one of the tanks needs to be replaced but i just checked these and they seem OK.

Any idea what can cause this?

Thanks,
Marcel

Ya might want to replace it anyways...sounds like maybe a crack or hole in the clunk line in the main tank

I had the exact situation on my Quick Learner. It was a slightly bent main rotor shaft, 0,2mm, that caused the heli to vibrate. Small airbubbles from the main tank went to the headertank when the maintank was half full. Is the shaft bent? Is the clutch correctly aligned? If the fuel tubes are OK inside maintank, look for vibrations! You don´t have to crash to bend the main rotor shaft slightly!

I would say that it is a split clunk line in the main tank I had the exact same problem happen to me.

The fuel clunk line in your main gas tank is broken or has a hole somewhere in the middle. I replaced my clunk line tubing with the regular blue fuel line tubing and have had 6 gallons of fuel thru it without a problem.
