I do not know how to check these things, so it could possibly be the problem. One more thing, how long do you let your heli cool before running another battery pack? I'm running my packs 3 minutes and letting the heli cool for about 8 minutes before running another pack.
i got told 10 minutes and i've been following that ever since. I apply this for my 250s and 450s. And if it's a really hot day, let it cool down even more! PS i highly recommend a better tail servo. Just like this video of this guy with his 250. notice he has a state of the art tail servo, but he's using HXT900 on his cyclic. A setup like that will do you fine. The turnigy 306gHV would be good to try.
