i had this in my losi scte, work great, i ran about 30+ batteries, i them pulled it out and put it in my 1/8 scale jammin x1 truggy, i ran it for about 3 or 4 battery's, and then boom. no steering and i can hear the servo running turning and turning and turning but not moving the servo horn. this says it puts out 236+- oz of tourq. it may, but it is not big enough for 40 series big joes on an 1/8 scale truggy rig, fyi, i put it in the truggy because it the larges servo i had at the time, o well, i guess its good feedback for all of you.
it looks as if the gears are brass, not aluminum or titanium. i gave it 3 stars for the quility of the meatal they used, but 5 stars on value, im not sure how strong brass is, but it may not be strong enough for the 236+- oz the servo can put out.
i was pleased on how cheap, and i will be buy more, but not for my truggy......
