Hi folks, I'm really frustrated with my T-rex 450. What's happened, the heli somehow locked in during a turn and just could not level it, resulting a "gentle"crash. After a good check, found that one of my servos failed (DS410m). Later on that night decided to check it again and this time it worked! Strange. Fitted everything back again but soon as I spooled up the heli started leaning one way, only to find the servo failed again. Ordered a new one and after a week tried my Trex with new servo. Ground check looked promissing. After a lift off did a small trim and off I went trying a gentle circle. Next minute out of the blue it started jerking then took off sideways until it kissed the ground. Reason? The servo I just replaced dead! What's going on? Could it be a problem with ESC? I appreciate your inputs.
