Hi Imrec. trying to fix your plane is a good idea, but I dare to suggest you to find in your area someone to check and trim your airplane before you fly it. It is difficult to learn to fly and adjust the
airplane at the same time. You can also buy a R/C flight simulator to speed up your learning curve and minimize crashing. Don't give up this hobby, it is merciless, like full size aviation, but it could
give you endless fun and joy.
