RE: RC Glider I was given.
A number of things in the pictures suggest your present isn't a glider.
Not to go into the long list, but to pick just a few:
Wing design MIGHT suggest a slope glider, but none of them have gear.
Fuselage looks like a scale jet trainer. It's pretty big and draggy for a scale glider, and none have huge jet intakes. And the nose piece looks designed to have a spinner in front of it.
Ooops, just saw your last post......................
OK, the Fouga Magister is a jet trainer. That's not a glider kit.
