HuiDa RC International Inc. is a high-scope company specialized in production, research and sales. There are experienced engineers and high-quality production lines, and they have established a great brand named HD.
Their company specializes in electric models, and also research new products based on the old products. They offer high performance products at lower price. They offer both analog and digital servos.
We have installed these servos in several of our planes and so far they have been great. I feel that the HD Power 2550A servo is the best analog servo available anywhere. There are only a few servos with more torque like the JR 8711, JR 8611 and Hitec HS-5955. Other than that, it beats just about all the rest. And at that price, it can't be beat! HD really hit on a winner there.

Use with JR servo arms
Part#MPISAJ1-MPISAJ4.
They are metal gear servos, not digital. Tough and strong. These servos will be good to use on your throttle with Giant scale airplanes and control surfaces for smaller planes. Similar to the Hitec HS-645 but with 70% more power. This is a revolutionary servo. At this price, it can't be beat.
Use with Part #JRHM3x8mm Servo Screws. |
OUT OF STOCK $23.95
