Ordered for hq 450. worked a minute and fused. I don't know. it's marriage or all the serves they have slag. I won't buy it a second time.
WORST servo step resolution I've EVER SEEN! From end-to-end, they have roughly 8-10 steps, they seem to choke on each (bind) as the stick is traversed across it's range and this means you will have NO fine control inflight. I was going to use them as camera gimbal servos but I see now they're NOT accurate enough for the task. Good for a CHEAP FOAMIE or maybe a boat.
These are smaller than standard 5g servos (thinner body) yet pack the same power, and with metal gears I believe are far superior. I have been building high speed belly landing foam aircraft, and these appear to be ideal! robust and accurate!!
good items
Great part if you purchase the XK X450 you might need 3 of these as the one's the product comes with are plastic and prone to stripping while changing flight from vertical to 3-D and back again this doesn't always happen but this product is great

Good quality. Fast delivery. Metal gear so small and less weight!. Very nice. I am happy with this servo. I use it for my Xk X450 VTOL.
ordered 4 of them only received 3 so 1 plane is not flying I guess
really tiny
I purchased 4 of these servos two were good and two were bad. still awaiting Banggood reply on the two bad ones.
