Hi,I bought this servo for my 450!
i want to use plastic servo arm like this : http://www.hobbyking.com/hobbyking/store/__14925__45 0_Size_Heli_Hitec_HS65_Compatible_Special_Plastic_Se rvo_Arm_10pcs_.html
but, i must buy Hitec HS65 or Futaba 3156?
Thanks
(sorry for my english but i'm French)
Thanks for the reminder. Ive looked at a few things. Access being one, and CG.Ive upgraded my ESC which is heavier on the other side of CG. Im moving the servo 2" I will assess it and perhaps have to move the battery down a tad, but we re talking about degrees / gramms thanks. I might end up putting 3 of these in my cyclics yet.
Pro use a DS520, but im going now for a Savox SHO-1290 on the boom
be careful of mounting this servo on boom of a PRO, the dodge is the CG It was originaly designed that the servo should be "buried" near to the centre of gravity and not way out on the boom.
Where is the warranty for this servo? It was working good until about the 10th flight (x900 tricopter) and the inner gear stripped. What a disappointment this servo is!
no.. the pro uses a standard size servo mount located inside the frame. there might a adapter or an alternate mount for mini or park size servos but I'm not sure :(. or you could go with the tailboom servo mount route.
Leon, I use this servo on my Tarot 450 Pro which has the same servo mount. I had to purchase a carbon fiber servo adapter to make the servo fit. If you search "450 Pro Carbon Tail Servo Adapter" on ebay, you can get them there for around $5 - $8.
My mistake. I see the servo falls under mini and park size servo category and I know this will not fit the standard pro mount without an adapter. was just going to next category my apologies.
I use this servo on 3 helicopters all hk 450 pro v2 and I have had no problems now at first one used to twitch with the hk gyro but now with the quark gyro never had a problem
only just learning to fly but have built a few helicopters now
Hey All,
I see this servo has a 4 star rating but when I look on RCGroups (plan to use it on the Turnigy Tricopter) I see this server is getting a very low rating with people having this servo strip the gears while in flight on the their tricopters (even without taking off). Additionally one minor crash without even hitting the tail in the crash is also stripping the gears. Anyone else having these problems and does anyone know if the gears in these have been upgraded to fix the issue?
so far i think most ppl rate 4 star on above servo because they use on 450 size heli on cyclic & tail servo (include myself currently use it too).
i don have experience on tri-copter and not sure how much torque required by tri-copter u built.
maybe i suggest u using park servo which can handle higher torque than this one.
anyways, this servo really bravo for cyclic for 250 / 450 size heli..!!!
Mine stripped, even just hovering... Used it in my very first tricopter build. 2 of these stripped or burnt out, dunnu how to look :( servos literaly are fast with the stock kk2 settings, so i used some lower expo/dr with another servo, worked fine :)
dun think so currently have spare gear...
if get MKS gear, the price would be near to buy a new set of servo.
my opinion u can find those buddycode in rcsearch**** then puchase extra servo. ur current one use as spare next time.
refer below n search the servo if have any body buy n posted the code at the www.link
I tried to use the MKS gears due to the wait for these servos from shipping from international store, but it was impossible to put them back together - too small parts for my skill, or lack thereof. Now I keep 2 spare servos around, since they're so cheap. Works fantastic of a 450Pro FBL.
Hi Frank,
i have 2 of these here for my Y-3 Tricopter Fleet an to answer your Question:
NO it is NOT programmable.
If this Answer helps you with your Question please feel free to let me get rewarded for best answer... cheers and happy easter
Never mind guys, I had $23.01 worth of fun melting down this servo with a torch and will never touch one again........makes pretty colors when it burns though :)
Is it good to be use as tail servo and is it compatible with the Futaba GY520 gyro? The GY520 requires tail servos with pulse width/frame rate of 1520us/280hz. Any suggestions for compatible & affordable tail servos for the GY520? Thanks.
i had been use this servo as my Trex450 tail servo with 1520us rate on my Align 780 Gyro. had use for more than 50 flight & more than 4 months already still perfome well.
think if the pulse is same. it shall be ok for GY520 as well.
thanks
No this servo cannot be programmed. Pulse width is 1520us - not changeable. I'm using it on most of my 450 Helis for cyclic and also as tail servo with 333Mhz connected to my microbeasts. Never had problems with it.
This servo does not work correctly for me. I test it on a servo master right out of the box and it twitches and jerks with no input and when it does move it is erratic. What should I do with it besides through it away? Is it worth the trouble to go through the HK customer service?
If you use it in an 450 Pro Helicopter you can use this Tail Servo Mount: www.link the Crosspiece you can use a Standard Servo and with it you can use your TGY306 as Tail Servo.
HK don't have the replacement gears. There are exact replacement* google kst115 to get a supplier near you. They're about $6 for the main output shaft gear. a few variants of these * Alzrc dsm45mg ,Tarot kst115 etc.
I took the servo apart to verify what replacement gear set was correct. Based on the pictures of replacement gears, the KST DS115MG was the correct gear set. Side Note: It appears that the main shaft was the weak link (the gear that the servo arm is attached), which is a good thing because it is easy to trouble shoot. The servo arm smoothly turns with no resistance. This is the finest mini servo I've ever seen in 25 years of flying.
The items haven't shipped so its not an issue with expidited shipping. The order has been canceled. Every time I talk to someone the ask if I'm sure I want to cancel which means the order hasn't been canceled at all. It's going on two weeks. So quite your whining about me.
Will either one of the bottom gear work with this servo? Thanks
BMS-20325 Metal Gears for BMS-306MAX
Or
BMS-20304 Plastic Gears for BMS-306 / BMS-306BB / BMS-371 & BMS-308BB
The BMS 306 are smaller servos so the gears won't be compatible. KSD gears tried and fits but need to use different servo horns . Cost is almost the same as getting a new servo. There are many of variants of these servos, check online for price difference. I've bought about a dozen of these and are one of the best.None has failed nor strip.
noob question, does this servo make a sound while on standby? i hear this little buzzing sound... still works though. i worried that it might be damaged, or does it really make that sound when it has power?
Arrived boxed up and with full accessary set. Good length on the lead. The case is well finished and looks good. There is zero slop in the gear train and the output shaft is free form wobble. The whole servo feels solid. The servo is fast on my servo tester, and basically I cannot fault it. I will be putting this to the test on a 450 tail, I figure it would also do equally well on a cyclic set up.
All gears are metal (some looks like aluminium, some - brass, and main gear is a bit different color as other aluminium gears, probably different alloy).
So far so good, very quiet, no slop (well, compared to 3 other 20-30$ servo i have here) and very very fast. And by telling "fast" it's not only numbers (for example, prod id 14279 "on paper" has the same speed, but on tester looks like turtle compared to 306G).
I do not fly heli, so can't tell where it could fit or it could be easily stripped away (like someone told in discussions tab), but i'm going to use it in very fast wing.
Overall - very good quality, and good price. Will buy more.
So far so good. Works great on tail of an older 450 v2. Really wish it came with a round horn as well. I have read about stripping the metal splines on a crash so I notched the horn just a little hoping it breaks if I ever crash. It's quite heavy for its size - but lighter than the mini servo I was using before it by just a few grams. But for cyclic I think you would be weighing down the heli quite a bit. Might be worth it though if using a FBL setup.
