You don't say what model heli you have. Sounds like it might be like my CPv3.
If thats the case there is a blind nut behind that screw. You have to look close
to see it. Because the part of the nut you can see is only about .020" thick
and the same color as the plastic. You'll have to hold the nut with something
like needle nose pliers to keep it from spinning. Don't feel bad it tripped me
up for awhile too.

Good Luck
