Ok, so I have a Seagull Super Star with a Saito FA-180 4 stroke. I can't get this thing to balance worth a damn. It's always tail heavy! [:@] I have an 1100 mAh battery under the fuel tank. I moved everything to the front. It says to balance at 7cm back from the leading edge at fuselage. This is the front of the wing right? I have to put 1lb 6oz of lead on the engine mount to get it to balance w/o fuel in the tank. I read some other posts and they said 4.5-5 inches is good, but it this really ok? Thanks for the help in advance.

That 7cm is at the wingtip, not at the side of the fuselage. That is equal to 14cm at the side of the fuselage. I found that 12cm behind the wing/cowl intersection works best. (In other words, right on the spar.)

I'll try that, but the instructions say "The center of gravity is locate 7cm back from the leading edge of the wing, measured at the fuselage." Seagull instructions aren't written in very good English so I wouldn't doubt that they meant wing-tip, but I was just making sure. Thanks for the help. If anyone else out there has this plane, I'm interested at where they have their CB set.

I had mine on the wing spar like jrf

mine is at 4.75 behind the LE at the fuse and flys great.
