Daniel Porter Verified Owner Tuesday, Aug 20 2024 (about a year ago) Holmes Hobbies HV150 High Torque Metal Gear Micro Crawler Brushless Servo (HV) Excellent servo! Strong, quiet, and centers well. Also comes with a metal horn. The only issue as with most micro servos is that the horn is only threaded for the scx24. I bought it for a Rock Van EVO so I had to widen it for m2 screws. But that doesn’t reflect on it excellent quality.
I ordered another one for the new Arktos 6×6…so I’ll be widening this one too. 1 customer found this review helpful. justin coulter Verified Owner Thursday, Jun 6 2024 (about a year ago) Holmes Hobbies HV150 High Torque Metal Gear Micro Crawler Brushless Servo (HV) This is the servo you are looking for…… being no stranger to the Holmes hobby products I was intrigued to see them break into the micro scene with an unstoppable servo. This will run on 5 volts no problem and will beat any other off the shelf servo like that but, I think it would be wasted if you not running it at the full 8.4 volts. At a competitive price with unmatched power in the micro servo range I cannot recommend this enough, although it is slightly longer than your regular micro servo you will have to get nifty and adjust accordingly. Well worth the price, internals are solid and can handle full 2s power with no glitching on top of 174oz of micro moving power those oversized tires and full aluminum upgrades won’t slow you down. 1 customer found this review helpful. Bryce Dupriest Verified Owner Monday, Jan 27 2025 (8 months ago) Holmes Hobbies HV150 High Torque Metal Gear Micro Crawler Brushless Servo (HV) Most Premium Micro servo I have ever used. Just heed the notes, it browns out anything with a small BEC (furitek lizard)and the Servo horn is for smaller than TRX4M Hardware. Mark Long Verified Owner Wednesday, Jan 22 2025 (8 months ago) Holmes Hobbies HV150 High Torque Metal Gear Micro Crawler Brushless Servo (HV) This says it is compatible with the Furitek FX118. It is not. There is no screw provided to allow you to connect the steering linkage to the servo arm. Frustrating. 0 of 1 customers found this review helpful. View all reviews
