I have a superstar 40 which is a flat bottom wing trainer and I have bent my front landing gear more than once I am afraid to say.

It should be easy to remove and straighten (well working it over with pliers and channel locks untill it looks straight) and when you reinstall it...make sure the nose of your plane points up when its sitting on the ground. My plane takes off just fine with the old LA .40. I do have to use about 25' of runway on a clam day. Take off is always full throttle for me. Thats how I was told to do it.

With the plane pitched nose up it skims along the grass after the first 10'-15' with a neutral elevator. I just lightly grab some up elevator and its off the ground.
