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.
