Great Power and Smooth Performance!
I used this 800KV BLDC motor on my RC speed boat, and it exceeded my expectations. The acceleration is smooth, and the motor runs very efficiently even at high RPMs. It stays cool after long runs, and the build quality feels solid and reliable. Paired it with a 60A ESC, and the setup works flawlessly. Definitely a great choice for anyone looking for strong thrust and stable control on the water.
