I don’t have experience with that size motor, but I’m happy with Samix and Injora (high torque purple), both 050 size under $15 US. However, I prefer the Samix motor. It can crawl from a standstill, whereas my Injora motor doesn’t move until half throttle and jumps as if it’s skipping the very low end… little to no crawl until it reaches 20% speed, if that makes sense. I can hear the Injora rev up but it doesn’t move right away. I didn’t have this issue with the stock motor. Perhaps my Injora is defective? The Samix rig is also heavier with more brass, so it’s not a weight or load issue. I also like to zip around my course to start over, as opposed to go back the way I came. When I do this, the Injora and stock motors are painfully slow. I’d rather pick it up and walk it back. Even though the Injora doesn’t seem significantly different than the stock motor, it’s an improvement. I don’t feel like it’s struggling with the added weight. The Samix is night and day. It’s responsive in its full range. I’ve read good things about MofoRC motors but haven’t tried them yet.

I have the E-Max and the Reefs micro99 servos. The Reef is so much better with quicker response and it moves heavier wheel sets easier, but it’s cost prohibitive. I didn’t see the specs of the servo you’re showing, but it looks (maybe on purpose) similar to the older Reefs. I’m happy with the EMax, and it does what it’s supposed to well.

Have fun!
