Using this combo in a CR18P EVO Pro and it's perfect for that little rig. Excellent slow speed control and super easy to program. Using the ESC in a FCX18 build and it's doing great. Can't go wrong with Hobbywing.
Great motor/esc combo. Has very good low speed and torque. Small footprint makes fitment a breeze. Although it does not come with a pinion gear. I used a Meus brushless transmission and it came with the proper pinion. I highly recommend!
This is a nice combo, I used on one of my scx24 builds, the only problem is finding a pinion gear for it. I used the furitek pinion gear which work nice but you to be careful with what tranny your using! All in all though a great combo!
Awesome little motor, running this in my trx4m buggy and THE ESC is inside my scx24.
Overall, the motor has great low speed control. However, the drag brake is incredibly weak and would not recommend this for any 18 scale. It’s a shame to waste this much money.
Reviewers generally praise the Hobbywing Quicrun Mini24 3500Kv combo for smooth low-speed control, good torque, easy programming and a small footprint suited to mini crawlers and scale rigs such as the SCX24, FCX18 and TRX4M. A recurring issue is that the combo does not include a pinion gear, so owners must source one separately; one reviewer found a compatible pinion from a third-party brand but advised care with transmission choice. One verified reviewer rated it 2/5, citing a weak drag brake that made the unit unsuitable for 1/18 scale. Ratings are mostly high, with one dissenting review.
- + Good low-speed control
- + Strong low-speed torque
- + Easy to program
- + Small footprint for fitment
- − No pinion gear included
- − Pinion sourcing requires care with transmission
- − Weak drag brake reported
