I took a servo, receiver and battery out of the plane and tried but still the same symptons as before. Fine for the first half minute then jittery then no control at all. I found the receipt and wouldn't you know it, I bought it exactly 2 years ago plus 4 days. That's 4 days after the warranty expired. I've never used this remote yet. Just my luck, eh! I might take it to the LHS to see if there is anything they can do. If I have to pay for warranty work on a remote that costed a little over $100, I don't think it will be worth it. The bill could be higher than the remote cost.
