i have a glider, more specifically the filip v. (just the plain glider, not the eletric version.)

im using a hi-start to launch it and it gets up there but i noticed that the nose is too heavy.

if i take my hand of the controls, the nose dips a bit.

now im not much of a builder and even though this is an arf, i had someone put it together.

what i need to do is reduce the weight in the nose but it seems like he put a bunch of small lead balls in the nose. i dont know if he glued them or solder then or what but i see a tight pack of lead balls in the nose. anyone know how i can remove a few of those? they seem "stuck" together.

also, when i take my hands of the controls, the glider should fly straight right? or is it normal for the nose to go down a little?

thanks!!
