im still new in the hobby and this is my first time coming across a balance problem this bad.i have a Nexstar .46 that didn't make it past its first take off. the problem tho is that its out of balance the CG is good its the wing tip that feel like it weights a ton. when i hold it by the prop and tail it tips right really bad. so what i want to know is whats the best way to correct this problem?

That's called lateral balance. I use fishing line under the top hinge of the rudder and on the prop shaft up front. Then I lift the plane by the line and see which way it falls which is usually to the right because of the weight of the muffler. Ill stack lead or coins onto the light wing tip until balanced. How I install the weight depends on the plane and the covering. If I can get away with it, Ill cut away some covering and glue the weight inside to the last rib and fix up the covering.

it shouldnt be that out of whack, once is in the air you wont even notice it, trust me...lateral balance isnt nearly as critical as CG..... if it bothers you, add some lead weight to the light wingtip

Lateral balance will show up in your loops drifting towards the heavy side.  I stack coins - as Gary mentioned - over the aileron servo and once it balances I pull the servo and tape the coins (or sheet lead if required) to the servo case.  Better to add it at the wing tip but that requires stripping the covering. 

Another tip is to insert nails in the light wing tip leading edge and epoxy them in.

Charlie, this is a Nexstar 46 and if stock, it has a single central servo. So, in that case, I would either put the weights as Gary suggested slot and glue into the wing-tip balsa block if it has one. Otherwise, as Gary suggested, glue them in on the last rib then add a small piece of covering to mend the slot.

The OP can also use some of those self-adhesive lead weights that we put in the nose to balance the CG. Heck, for short term tests, those can be placed right on the clean covering on the underside of the light wing-tip and stick one or two right to the covering, fly it to make sure it's ok, then, once satisfied, put them directly on the balsa wood under the covering.

also make sure you're not on a compression (exhaust or ignition) stroke, the prop should be loose on the crank, just when you're using it to test lateral cg of course... You can tighten it up after..

my Nexstar wing is set up as a dual servo because i couldn't use the single servo the built in arms to the ailerons was really out of wack. this plane has been a problem from day one on its first take off it made it about 3 feet up and the fire wall ripped and the plane smashed nose first into the ground. its not over powered it only has a .46 size motor one thing about the nexstar is they look nice but if you get the select its better QC and the ARF like i have are from bottom of the barrel.

I'm not a big fan of the nextstar myself but others seem to love it. Anyway, as mentioned, lateral balance isn't a big thing for just flying around during training, it trims out. It does show up during stunt flying though so you may as well start the hobby by making lateral balance part of your set up for all planes. I just use stick on wheel weights like CG mentioned to the wing tip of the light side. I usually don't bother removing them and then hiding like others do on a trainer. Trainers are a tool and I don't bother trying to keep them pretty, they don't stay that way long after my students are finished with them.

I'm wondering if you have something else wrong. Set the plane up on a flat table and looking from the rear, check the height of both wing tips to the table and if the wing and horizontal stab are parallel.

Ah.. well, in that case...
