Im about to take out the tank and check all fuel lines but I did not see any bubbles and thats usually the first sign of leaks in the line. Maybe there are some leaks....Ill check. Its actually the nitro models version which is a direct cut from the H9 version. I was gonna get the H9 but I liked the idea of fiberglass so I went with this one. They really have improved this version from nitro. Yours will probably handle even better since it will be a little lighter than 11 pounds! FYI- I needed to add weight to the back of the fuselage so I just used some servo extensions and put the receiver battery toward the tail. Balanced beautifully. Ill post some pics tonight
