Make sure your prop is on correctly. Make sure you have a full charge of your battery. Make sure your elevator points up when you pull back on the stick. You must launch in to the wind. I learned with an easystar. I would have my 16 year old run slowly and gently toss the airplane into the wind. He does not need to throw it "up" much. Just a little over level. I cannot remember what the center of gravity was but is was not terribly critical. A cheap center of gravity device can be made with a 2x4 and two pencils. Drill holes about a foot or so apart and insert the pencils. If desired add extra erasers on the top and it works pretty good. I have made every mistake and I am still crashing........ But I have fun. Do not give up. If this does not work let me know. I will check back. Easystar is a great airplane
