Hi,
Glad you found the problem as discussed. Go to your (LHS) local hobby shop and buy one for $6.99 or any website of your choice. I have a placed one site below to show you what your looking for and the part numbers. I "don't" recommend you buy an aluminum one "unless" you want to have shorter fly times. The more aluminum bing or needed parts you put on, then the Heli becomes heavier and thus shorter fly times. I have only had this happen once and my friend once, and both were from crashing often when I was a newbee. Hang in there!
