Powerful, fast, precise and accurate servos. The precision is very good almost 0.2/0.3 degree of error, that is the value of the free play (almost null). The weight is 13g They need a bit more power (compared to analog servos) so if you use many of those use an appropriate BEC. They work well with 1s lipo (3.7v), but never used more than two at the same time with this configuration. Delivery in Italy was faster than expected. Just a negative point, if you press along the side of the gearbox (upper side) you will increase inner friction, probably a gear that crawls on the deformed gearbox inner walls: just don't clamp it in a vice or so. Best choice for a 9-13g servo. better than more expensive servos.
very good,thank you.
