Just from hanging out in the pattern forum. Guys are saying they are not as precise due to a deadband something or other. It's easy to get hung up in all this stuff, but you're totally right in that at this stage I probably wouldn't know the difference, and switching to a more accurate servo when I can actually tell the difference will be a nicer way to go.

Hitec 5625 has all the power I need and tons of speed so is probably the way to go - only $55 as opposed to a JR 8411 for $95.

Thanks guys!
