Well, if you want to go to hi-torque and stick with hitec.. the 645 seems to be a pretty good bargain at $37.

As I said earlier, I stick pretty much with Airtronics. They are a tad bit more, but that's just about all I've used, and I have a lot of them in use. All the planes shown in my signature line below are equipped with them. I get great performance and they back them up. I've had one go bad, fortunately I caught it before a flight, so no harm done. Actually, I take that back.. Tower backed it up.. sent me a replacement right away, no questions asked.. never asked for the old one. But, as I said, whatever is your cup of tea.

I do own a few hitec's for my electrics, I must add, and they have given me good performance and they are inexpensive so I don't mind glueing them in the foamies..
