One other thing to consider... is this the same receiver that has been through 2-3 crashes? If so, did you get it checked out and repaired if needed? I witnessed what happens when you fail to do this a few weeks ago. A guy at my club had a beautiful GP Shoestring and used a receiver from a crashed airplane. In spite of experiencing a couple glitches in a previous flight, he convinced himself everything would be OK. On final approach, the plane glitched bad an basically spun into the ground.

Disgusted, he vowed that he had learned his lesson and tossed the receiver in the trash. Miraculously, he was able to rebuild the plane but it will never be quite the same.

After my Cherokee went in, my Spektrum receiver was in the mail on it's way to Horizon first thing on the Monday after. I'd rather play it safe. If the repair cost is too high, I will scrap it and get a brand new receiver.
