yup, lil toooooo lean.
to lateral balance, grab an assortment of samll finishing nails ( very small head ) say 1" to 3" or so.
Pull out the plug so the engine compression doesn't get in the way, hold it from the very tip of spinner, and very back of fus, right in front of the rudder.
probably take two people. You have to hold it lightly, one finger tip if you can, so that you allow it to move easily.
Gently pick it up a few times, if one wing is heavier, it will tend to roll that way, even just so slightly. Try the different nails by laying them on the very end of the wing tip. Keep lifting and seeing what the results are. When you have the right balance, tap the nail(s) into the outside edge, more towards the front, so that nail is facing the fuselage. Shouldn't take much. Mine needed 2x3" finishing nails. The further you can put any weight, front, rear or wing tips, away from the cg, the less wgt you'll need.
You can use a drop of ca to hold in place, a strip of covering if you have, or some clear tape. There is scuff tape that will work great & save the tips for those occasional tip hits also.
Glad it went well, happy flying!
ps- knees knock a little, its ok...we all have at some point

RE: New Hanger 9 p-51 mustang... - 
My instructor got there and he went over the plane with a fine tooth comb. Checked balance, checked throws, checked directions, checked to make sure the fuel clunk was free and so forth and so on. He said that she looked very good and was impressed with it as a "trainer". We get it over to the table and fueled it up, range checked it and fired it up. We decide to lean it a little and then let it run for about 10-15sec wide open. I take her out of the rack and put her on the ground and she taxis great through the grass and is sitting on the run way getting ready to spin up. There was a moment of fear, excitement, anticipation and about 40 other emotions going on in my head. He slowly laid the coals to her and the take off was abosultley gorgeous, nice and smooth rotation and then a gradual climb out. If I saw it on a film I could easily be lead to believe it was an actual mustang taking off. He does a few laps trimming her out and stated that it did not actually require much of anything to trim it out. It needed some right aileron and a little right rudder. I am going to fix the right aileron trim by placing a small weight in the right wing servo tray. I may not have got the lateral balance perfect. 
Well since neither of us brought a buddy cable, he just took it up about 3 mistakes high and asked if I wanted to fly it. Shonuff I did, so I took the controls and did a few laps and tried a few moves. Then my instructor asked me if I was cutting the throttle and I told him no I was not. But you could tell the plane was losing airspeed (even though it was already flying slow). I hand the transmitter to him and the engine dies, deadstick on first flight, needless to say my butt puckered up pretty tight. All I could think is my plane was going to have a very harsh landing on it's first flight. Needless to say Dan (instructor, soon to be FIL) brought her down as nicely as I think anyone could in the situation. The saving grace is that the field I was at was wide open and he was able to get her down in some rather tall grass and there was zero damage, but the engine was UBER MUCHO hot. It had started to rain and as I was walking back to the pits with the plane rain would hit the engine and sizzle. Dan thinks we prolly leaned it out a bit too much and with the engine only having had two tanks through it other than this one it is not broke in enough to lean it that much. So we let it cool down as the rain went on for about 10-15min and then we refueled it and took it back out to the flight line. We richened the engine back out by about 1/2 a turn and ran it for about 20-30sec before taking it back out on the runway. Another gorgeous takeoff and flight. Dan then was bringing her in for a normal landing and absolutley greased it. It was great.. I will be back out there tomorrow..
