Tekin Redline T8 GEN3 4038 1/8 Truggy Competition Brushless Motor (2250kV)
I grabbed my first one of these with my Tekno ET48.3 along with the RX8 gen 3 a couple years ago. I ran the crap out of it probably 5 packs a day, 5 days axweek for the furst month I had it at my smallish, dusty hard packed blown out local outdoor track that has a combo of tight hairpins, fast rolling jumps and huge table tops and 2 doubles that clear 20 feet. Never once have I wished I had more power and in fact Im sure I could probably turn faster laps with the 2000kv version, if not even the next size smaller as the truck sees full throttle for maybe 1 second per lap at the start of the main straight and sometimes just a quick blast before a jump. I run the Protek 6500mah LiGV packs, and have the Tekin RX8 Gen3 esc T8 combos of various ratings in my other Tekno EB48.4, EB48 2.0, SCT410.3 as well as my new TLR 8ight-Xte that Im finishing building up.

As far as comparison to other motors and esc's, I owned a couple Castle setups, and while they might be as good ir better for straight bashing or 100mph speed runs, there is no comparison when it comes to track/racing performance. These are so smooth and the bluetooth dongle and phone app have all the needed options to dial everything in. The only complaints Ive had with any of the Tekin stuff is that every once in a while I have to attempt to link the bluetooth tuner to my phone several times, with it taking 5 ninutes or more of doing different things to get then to link, and I would also like it if the BEC voltage could run up to the 8.5 volt range for the higher voltage servos, but the 7.4v still is plenty for all the Protek 170SBL and TBL servos I use in all 1/8 rigs. The only other problem Ive had was my fault, but could have been avoided. Because the wifi dongle is so small and can be left plugged in while driving, I was making some changes with it and before removing it I was sidetracked by another driver for a couple minutes, then threw my body back on and left the pits. After a few laps I noticed a small white part fly out of the truck and immediately realized I never took the dongle out. The wire had wrapped up in thevrear driveshaft and the box ripped off the wires. Surprisingly I was able to solder and repair everything and it continues to work perfectly to this day. Even if the esc gave a couple beeps if selecting the option to drive the vehicle while the dongle is still plugged in to the esc, I would have remembered to remove it. It is awesome that you can pull into the pits, change esc/motor settings, then be back on the track in literally a few seconds which allows you to really compare how changes in settings effect the performance. While it would be nice to permanently have the programmers installed in all my tekin equipped rigs, for whatever reason the dongle plugs into the same port as the fan so its one or the other. Not sure why so many companies do that and cant just have a simple 2 pin jack dedicated to the fan.

Anyway, these Tekin 1/8 motors are the best Ive used and will continue to buy them until there is a reason to change. I want to try the Maclan and Hobbywing 1/8 stuff as I love their 1/10 and SCT stuff, but ive never used or driven either.
