Features; High Speed Carbon Gears. Ball Bearing support Excellent for park flyers and shockflyers. Alloy heatsink allows potentiometer and motor cooling.
nice servo. should i use the rubber cylidrical shaped object when i mount the servo? Or is it enough to just mount with naked mounting screws that dont go through the rubber. I guess this is for minimizing vibration, but the rubber really makes the mounting seam "loose"
Just a heads up on a potential reliability issue, I'm a big fan of this servo as a 450 tail servo and they have served me well till today. I had done about 100 flights on this servo when today it began twitching badly in flight before I lost tail control completely and had to auto it down. The signal wire had broken clean off inside where it is soldered onto the pcb. These are very well built servos and despite having a rubber grommet on the wire I suspect vibration transferred down the wires and caused the failure. The wires are fairly stiff aswell which may not have helped. Keep an eye on this and perhaps consider doing a touch of hot glue preventative fixing on the wires (as I have done on this one after re soldering the loose wire) close to the solder points to avoid this type of thing happening to yours.
So again, awesome tail servo but check periodically to make sure wires inside are still looking strong.
No rubber, just mounted directly into the servo mount on the Trex 450 pro using an adapter plate. I'm not sure using rubber grommets would have helped in my case as I suspect all the movement was coming from the wires themselves, I had also run the wire fairly tightly along the side of the servo rather than underneath which may have put a bit too much tension on the cable on one side and negated the effect of the rubber wire seal to dampen vibrations.
for cyclic yes, but for rudder you will need to make an adapter.... for tail it is better to have larger one... anyway if you want that one for tail, wake up a modeller from you and give it a try. i am sure you wont miss
I just installed this servo in my HK450TT Pro, coupled with a GA-250 mini-mems gyro, one thing I noticed (without fliyng) just testing in my lap is that when move the rudder stick and let it back to center, the servo arm does not return to the original position, if I move the heli tail, it moves quickly to compensate, but not centers back when move the ruder stick, It's that ok? I am realy a nubie in helis
Yes, this is completely normal. If the gyro is in heading hold mode it will not centre the servo when you centre the transmitter stick.. If it is Rate mode it will centre the servo. This is normal. They gyro now controls the servo, not the transmitter stick.. by inputting a control input IE a left turn.. the Gyro moves the servo to perform a left turn and will hold it there until the helicopter turns.. Try it.. input a left turn.. then physically turn the helicopter left.. the servo will the
why hk took out the link that would help sell their products I haven't a clue. Find spartan-rc, then go to the support page and scroll down, find the servo data button and click on it. Nope you are not there yet. See if the servo is listed on their servo selection table by finding the click [here] button. Btw the Futaba servos they sell with the GY401 has the identical pulse and frequency as this servo.
Just add it to your cart, you will be surprised. Is it really identical with Futaba FS 555 BB? I saw the Futaba perform really astonishing on the tail of a friends 450, he pitched it up hard without the slightest sign of breakout on the tail. Price of FS 555 is near 80$ here in Germany. Want one so badly :)
How wont it work? it is deffinately a 1520 servo, you could try a 250hz update rate vs. the 333, but unless you got a bad servo or didnt set it up right, something else is wrong.
I am running 1520/333 on my mini-G just fine.
Lots of guys are running these on 500 class all the way down to 250 class. Not sure where heyya is coming from-but there is a chance he got a band one. Also programming your gyro correctly is must to not fry it.
