Yes, I am using one in my Randolph Bee-Tween. It's a few dollars cheaper than the Berg, but only has about 1/3 of the range. I bought it before I found out about the Bergs. Personally, I would go with the Berg, and BTW, people have been sharing servo channels with battery packs forever. Berg also make a 7ch for $51 that is full range, too:
