Since you are going it alone, your issue could be a plane that isn't set up correctly to start with. Find some tall grass. Toss your Bixler so it will glide and crash into the tall grass. That will protect it from damage. Watch what it does; you want to see a straight glide and smooth drop at the end. Try to do it when the wind is calm or at least blowing in a direction that lets you launch straight into it. Once you know your plane will fly straight, you can work on making it handle straight on the ground. And once it will do that, you'll know that it should takeoff straight. Flight trimming is a whole 'nother set of skills we can help you with too. For your first few flights, takeoff close to that area of tall grass I mentioned before. You can cut the throttle and crash the plane into it to save it from damage. Once you have a little more control, try to fly the plane level into the grass. Then work on touching the wheels to the ground just before getting to the grass. Once you can do that, you'll be able to land normally.
All that said, even just one session with an instructor will save you hours of frustration and significant money. Consider finding someone to help you even if it means driving for an hour or two to meet them. It's worth it.
