Great speedo the program ability is awesome! You can get it set for any driving style. You can program it to be smooth or super aggressive, hard or soft brakes. With the hot wire and the quick tune buttons on the esc it makes for adjusting for any track conditions quick and easy. The data logging is unrivaled by any brand of esc.
I purchased one of these from the first production run in Feb 2018. Used both an original HotWire 1.0 with USB as well as the newer HotWire 3.0 with Bluetooth for programming. Both worked great, and this ESC features lots of tuning ability to get it setup just the way you want. Another good reason to invest in the HotWire is the data logging ability, of which is unrivaled in the ESC market. Data logging can be useful for many things like fine tuning motor gearing (ability to watch motor temps, RPM, and throttle amount). Bottom line, this ESC is very smooth, feels great on the track and features strong brakes if needed. I'm using it for 2wd buggy with 17.5 spec stock and 7.5 mod, zero complaints.
Performance is outstanding. These have been hard to find but a main got one in about a week.
This is one of the best 1:10 scale esc’s around. It is super small which makes it perfect for kits that have tight spaces for electronics. I use this one in an outlaw 4 and it fits great. tekin’s customer service is above all and is there for any need you may need with there electronics. You can purchase the Hotwire separate for even more dialed in tuning via Bluetooth from your phone.
great esc from a great company. ive been using tekin products since the early 90s and never had any issues. same holds true for this esc. ive had the original rsx as well as the pro. i liked the solder posts a little better on the original...they were a little longer and i think a little bigger in diameter. but overall i cant complain. for those of you having trouble getting the hotwire3 (bluetooth) to par and connect to an android phone...make sure your gps/location is on. idk why but it has to be enabled. you can disable it again after your done tuning but have to enable it again to reconnect. i fought with this for months then finally called randy pike (before he left tekin) and he told me to enable gps...bam it worked right away after that.
Reviewers broadly praise the RSX Pro's smooth, responsive performance, extensive tuning options, and data logging when paired with the HotWire programmer, and several note it is compact enough for tight chassis. Some reviewers report difficulty connecting the HotWire Bluetooth module to Android phones, which one says was resolved by a Tekin app fix and another attributes to location settings. Support responsiveness draws mixed comments, with one reviewer reporting unanswered calls and emails and others praising Tekin's service. Two low-rated reviews cite delivery delays and an apparently used unit sold as new with a damaged receiver wire and broken heatsink bolt. Several reviews concern a single retailer or shipping experience rather than the product itself.
