I feel for ya, I personally have been through all of this. Cheap chineeze parts just dont hold up to the crashes we give them. As you get better you will fly higher and the crashes will be even more devistating. You find youself doing more repair time than flying time. This got really old to me really quick. I am hoping the site wakes up the rc industry to quit selling us stuff that wears out and gets a replacement fee quick. Just look at the hobby stores, they sell flybars that I am afraid to put in my pocket, let along crash with. I know what a damn near perfect driveline sounds like, I havent crashed my heli since the last rebuild, I have been very careful with my airsliders... lol. It will handle a crash but, lets face it, the first time its rebuilt is the best.
