Product Review (submitted on February 1, 2013):

I bought several of these servos for use on the swash of a 250 sized heli and various scratch built airplanes. For the price, they are excellent. They are advertised as being slightly faster and stronger than the comparable (but cheaper) SG90, and I can't dispute that. They do seem to be stronger and faster, though I don't have the equipment to measure it objectively. They are also advertised as "carbon gear", but to me it just seems like black plastic. I can't tell if they are much different from the white nylon gears in the SG90s. Time will tell if they hold up better in a crash.

The only problem I have with them is that they seem to have poor resolution, and are a bit "notchy". Rather than being perfectly smooth across the whole range of travel, they seem to jump a bit from one position to the other. It doesn't seem to affect anything at all, and they still perform great, I just wasn't expecting it.

Overall, I'd recommend them and they perform great. If you think you need a little more force than the standard SG90, these are a great alternative and only about $1 extra.
