Review: Works - not bad.
Review: Don't buy - Buy something else. These are junk. I had a 3.7v system in micro airplane and one failed after just testing it with no control horn hooked up. So I replaced it with a different brand. The other one failed during first flight. I was lucky to retrieve aircraft with out a rudder. Complete junk from China.

### ⭐ Don't buy
*by B***S on May 14, 2025*

Buy something else. These are junk. I had a 3.7v system in micro airplane and one failed after just testing it with no control horn hooked up. So I replaced it with a different brand. The other one failed during first flight. I was lucky to retrieve aircraft with out a rudder. Complete junk from China.

### ⭐⭐ Smoked...Melted housing.
*by P***N on December 24, 2024*

Size was right, good torque. But after installation trial with no load, one servo produced a puff of smoke, and melted housing by the motor (pics). Other still functioning as expected. Will order replacement from different vendor, i.p.
