AGFRC A81BHPW 23kg Waterproof Servo

I got lucky and picked one of these up on eBay for under £40 and super impressed with this one. Probably the fastest servo I’ve come across. It’s also practically silent in operation.

It’s a Chinese made servo, built to a very high standard. AGFRC are actually an OEM maker for a number of other super high grade servo brands, so their own products are sort of a showcase of what they can build at a variety of price points.

It does however have some beautifully translated literature. My favourite line on the website page is probably this absolute gem:

    “Even in the wet and drizzle environment, can also satisfy your love of a model heart.”

Pure poetry I’m sure you’ll agree!

Anyway onto the important bit; how good is it?

This is a really very high quality servo. Strong, fast, quiet, and it re-centres really nicely. It's got plenty of torque, even at 6V, and is still very rapid. It goes al the way up to 8.4V and just gets increasingly powerful and fast! I’ve currently got it fitted in my Yokomo SO1.0 2WD racing buggy and, even with my poor mans ESC and motor, I can’t really think of anything that could make it significantly better for that application.
