gran servo preciso nel centraggio ottime prestazioni e resistenza montati 3 nel piatto del mio goblin 630 ad alte sollecitazioni 3d molto resistente e molto economico per il prezzo ne comprerò altri.great looking servos , all gears inside are hi quality but do need grease! overall I'm very happy with the speed and they stay cool! best 550-600 servo for the money...I have 3 of these on my 550 for cyclic. The servo works very well, no heat issues, and is fast and strong. Centers well too.
However, would not really recommend for for the 550 (clone) since it is too deep for the back to back mounting in front of the 550 frame. Was able to make it work (barely) but get a servo that is not as deep, and save you the problems to make it fit.
But the servo itself is very good, just not the right size for the 550.Great budget servo. Price is right for a decent servo. Cheers 50011, , . , , , .I have installed 3 of them on my Hurricane 550 equipped with a FBL head and a Vbar. After about 50 flights, they just work great, very powerful, fast enough (but not as fast as described, maybe 0.10s at 6V) and centering is quite good.
They jitter a little too much, which increase their consumption, but that's not a big issue.
I think they are a very good & cheap choice for 550/600 sizes helicopter, if you don't want to pay the extra mile and wants to have a cheap helicopter for training of course.Really impressed with the speed and the torque of this servo. The fastest servo I've had to date and at a really great price. Brilliant considering it's a digital metal geared servo.
I'm running them on 6volts. Weight wise possibly not suitable for some models but I have them in a 68" cap232 with a 25cc moto so they are perfect so far.WOW Very surprised with this servo! I see that everyone is using this for Heli's but I have it in a SC10 short course truck and it has ample torque and the speed is insane!
I will buy a couple more for my buggy and drift car, this servo is crazy fast with the amount of torque it has.
My only wish is if it was water proof, then I could buy more to replace my bashers.Blue Arrow is the manufacturer of well-known Mi Servos. Very high quality servo. I have bought 3x of these for my 600 EFL frame to use them as cyclic servos and 1x D50012MG for my rudder. They are great, very powerful, smooth and quite fast on 6V but I think the grease inside is insufficient. Re-grease (just to be on the safe side) and enjoy :)TREX 550 helicopter I use more than 100 start there and they work perfectly, good for the middle position, strong and very fast.
