I just flew my t.o.c. edge pro for the first time this week with a ys 110.The engine runs great,but on my down lines it eventually struggled for fuel and died twice.The plane has a real thin gas tank that fits inside the narrow fuselage,it looks to me that the clunk is not falling down the otherside of the tank when the plane flies downward for a long period of time,such as spins from high altitudes,what can i do to remedy this??Ive think ive seen a tank one time with two clunks??Need help,otherwise the plane flies great.

I have the same plane with a YS as well, where the single clunk normally goes install a -Y- fitting and install two clunks. If you have difficulty with this set up you might use a -T- fitting in place of the -Y-. Good luck and be well.

thanks,im gonna give it a go.

don't use two clunks inside the tank. If EITHER clunk gets exposed to air, the engine will suck air and die. So by using two clunks, you double your chance of killing the engine. The clunk should stay in the back of the tank at all times. it should fall to the lowest point in the back of the tank, but it should never fall into the front of the tank.

Try a shorter clunk line with a heavier clunk. But be ready for problems if you prop hang towards the end of the flight.

Get a thinner Tube -- It should be long enough for the clunk to reach the bottom of the tank -- when you go down line clunk should not come fully to the front of the tank as it gets stuck most of the times. Also you may wanna try your down line moves while your tank is half full.
