Holmes Hobbies TrailMaster Sport 550 Brushed Motor (21T)
I'm quite surprised nobody has yet made a review of this motor in this site. Well, for starters it's the best bang for the buck motor for budget-conscious hobbyists/and or beginners like me who wants to upgrade their stock motor. I have read and watched a lot of reviews praising this $20 motor, and so i put it in my Redcat Gen8 and TRX-4 rigs. Paired with the HobbyWing Quicrun 1080 ESC, that combo is unbeatable in cost-performance ratio in my opinion. Holmes Hobbies really did a great job, this motor runs smoothly and has a lot of torque,runs cool even on 3S, quiet, and durable.
