aerobird challenger-right left only

[970chev]

Hello! I have had this Challenger for about a year now. It was given to me brand new and I have learned to fly with it. I recently had a crash and now it only flys left when you launch it and will spiral into the ground. The tail had come unclipped inside so I snapped it back into place and used a wire tie to secure it. I replaced the tail with a new one. Of course I checked the trim and cannot see anything wrong. Visually everything looks straight; I even took it to our local hobby store and they couldn't see anything wrong with it. After a year of hard flight I am looking to replace it. I would really like to figure out what is going on with it-ITS DRIVING ME CRAZY!

So I have had this problem with my aerobird challenger wanting to go into a sharp climb then a left turn and dive into the ground. Still haven't figured it out yet-it was a great flyer for the last year or so. I recently purchased a Swift. Tried it out and guess what? Hand launched it, climbed into a left turn and dove into the ground. I can only assume its me. What is a good method for hand launching? I have read some posts about the Swift wanting to "tip stall" and that sounds like the problem I am having with both planes. Anyone have any ideas?
