Includes 1 review aggregated from around the web.
There are very few reviews for this servo on the web. A German forum member says AGF-RC servos in his gas-powered P-47 have flown a lot since this year with no problems, and another member compares the maker favorably on price with Savox and Hitec servos he likes.
