RE: Aerobird Swift problems.
What you described is an Easy Glider Electric. Low cost aileron glider made of Elapor foam. Stock Speed 400 is adequate to take it up to soaring height for thermalling, or to take it out to the slope lift. If you want spirited performance, go for the brushless upgrade.
Paint it up nice it it looks great! Mine has a sort of navy look.
You can set up a drop module with a servo. No combat module but it is tough enough to take a hit.
Based on what you said, this is what you want, or tell us more.
