Xpert RC teased limited editions of their
SN-4401 brushless and PI-3401 low-profile servos back in July, featuring the engraved signature of team driver Lee Martin. There are two "Lee Martin edition" servos now posted to Xpert RC's website for the U.S. market, including the PI-3401 but also an SN-3401, which is a little bit faster (.070 sec. vs. .085 sec. @ 6V) but not nearly as torquey (174.89 oz.-in. vs. 255.39 oz.-in. @ 6V) than the SN-4401.
However, photos found on Answer-RC, the UK distributor for Xpert RC servos, shows not only the PI-3401, but also the SN-4401 and an SN-5401 that's a bit slower, but even stronger, than the SN-4401. Looks like Lee is getting more special edition servos than we originally thought!
Here's the full line-up. An email to Xpert RC USA asking about regional availability of each servo was not returned by the time this was posted, so check back for an update.
All servos feature:
- Brushless motor design provides extremely high speed, top efficiency, and low power consumption.
