Joseph Blas Friday, Sep 12 2025 (2 weeks ago) Hobbywing Quicrun Mini24 Waterproof Brushless ESC Combo w/1621SL (3500Kv) 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! E Monday, Dec 30 2024 (9 months ago) Hobbywing Quicrun Mini24 Waterproof Brushless ESC Combo w/1621SL (3500Kv) 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. 1 of 2 customers found this review helpful. Michael Rocha Verified Owner Sunday, Nov 17 2024 (10 months ago) Hobbywing Quicrun Mini24 Waterproof Brushless ESC Combo w/1621SL (3500Kv) Awesome little motor, running this in my trx4m buggy and THE ESC is inside my scx24. Kyle C Verified Owner Tuesday, Feb 4 2025 (8 months ago) Hobbywing Quicrun Mini24 Waterproof Brushless ESC Combo w/1621SL (3500Kv) 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. 0 of 1 customers found this review helpful. View all reviews
