Go ahead and give up on it, but don't throw it! I had one for awhile and experienced the exact problem you stated. I called Hobby Services and told them I was unsatisfied. They told me to send it back for full credit. I used the credit and bought a ST G45 and haven't looked back. I understand the draw of the tower engine..BB,ABC and cheap, but you can get the same thing with an ST and it's a better engine.....I think they are offering a $10 gift certificate with the ST's now, so that will cover your troubles and shipping
