Turnigy 555MG designed for F3A low profile performance, better precision movement and low electric impedance. This low profile servo is also a great choice for retract gear as well as thin wing ailerons.
Features. 1. Metal gear 2. Smooth cut curved gear. 3. Double M9.6 ball bearing (si-oil) 4. 3 pole strong torque motor with low signal affect and CE certification. 5. Rubber fitting case for waterproof 6. Same with Futaba 25 tooth spline 7. Heavy duty servo case
Weight: 19.5g Dimensions: 30.00 x 10.00 x 34.00mm / 1.18" x 0.39" x 1.33" Torque At 4.8V: 4.2kg/cm , 57 oz/in Torque At 6.0V: 4.7kg/cm , 181 oz/in Speed At 4.8V: 0.15 sec / 60° at no load Speed At 6.0V: 0.13 sec / 60° at no load
Can someone please tell me whether these servo's are any good for ailerons and a Alloy DPS 70mm 5 Blade Electric Ducted Fan Unit - Light Weight Version 4000kv. I need to know ASAP! please.
Hello Mickel
it seems you question is not on the right subject. the Alloy DPS 70mm 5 Blade Electric Ducted Fan Unit does not need any servo.
Hope this help.
Enjoy flying
Well, I ordered two of these and when I got around to testing them the hardware package was missing from one of the servos. No problem I thought, they want pictures of the servos and the box and the shipping label. Well, I'm not one to keep boxes laying around so it is long gone. No more servos for me from HK. I can understand the procedure for returning Lipos but this is crazy. BTW, the servo does work but I will not use it as planned because I need a matched pair.
Hello Kevc
don't be so sad. HK is doing a good job, bringing us good devices at a really low price. Yes for sure there is a mistake from time to time, and yes I'm sorry for you. But understand that the service has a cost, and the price they are selling is with NO service. Worst should be you have to return it to receive a new one. it will cost you more in postal price. Just go to your LHC and buy 2 sets of your missing parts. Then check what you pay for it. or order a new servo and you get some spare parts :-)

I have a problem with these servo...when i press the aileron with a finger the servo start a vibration....some time during the pressure the servo move the aileron of 1-2cm and after 1-2 sec. go back to zero.Anyone has these problem with this servo?
I had exactly this problem with one of my 555MG.It got so bad the aileron would drop under its own weight.Only thig to do is change it.Another servo bunt out on landing(not gear strip)after merest touch on flap.That is two u/s out of eight!!!! RayE
I bought 3 of these turnigy 555 servos. Two of them are flying nicely now in my f3b glider but the third can not get the center properly and is in reserve for spare parts.
Bonjour Alain, j'ai dé*jà* commandé* ces servos quand il etaient noté*s 5 etoiles.Les derniè*res productions ont l'air moins fiable(noté*e 1 etoile).Franç*ois Cahour en dit beaucoup de bien sur son blog rcpilot. * Flipair
J'utilise maintenant les MKS mini en lieu et place des 555, ils sont plus rapide et digitaux mais beaucoup plus cher et les bras sont en plastique...c'est l'é*volution...
I want to use them in a 1,5m aerobatic plane as aileron and elevator servo. But i don't know if this works really good because the look more like glider servors....
They have pleanty of torque,almost 50 in/oz.This is about the same as a standard size servo.Also they have all brass gears except the output which is aluminum.It also has a top ball bearing.Only the mounting is different
i would not see a reason why not to use them on aerobatic planes. i have them in 1,5m full carbon F3F glider for slope soaring. flying with high speeds - huge airerons result in heavy servo loads.... no problems with them. als the speeds are slower in motorplanes i would give it a try...
You can use these in your plane without any doubts. I use them in Piper J-3, 1800mm as ailerons / flaperons. The servos working flawlessly. Stronger then standard size HS-422.
They work perfect with the 617 receiver but not with the 608 and 6008 receiver.They only work with the 608 and 6008 receiver when you put the transmitter on, and the RX in on position,and if you then put the servo's in the receiver,then they wil work.
Has anyone measured the current consumption of these servos under load? Have you had problems using them with a PPM (FM) receiver? Thanks for any infos!
Guys, I did some more testing to exclude possible low pulse voltage (2,8v) on older Futaba receivers. I connected servo to newer receiver (3,2v puls height) and via and EMCO TEC DPSI. Results ae the same. Servo won't work ! It drives me nuts
NO they do work with 2.4 Ghz Futaba. I ordered 5 and are all useless. They only work if yiu connect them to the receiver after it has been powered on. Makes these servo's useless.
Bought 4 of these and they are quick and powerful BUT, one of them only works if plugged in after the receiver is powered up, and this is on a PPM receiver. This unit has a date code 12/09 but the 3 that work are date code 01/10 so maybe the newer ones are OK. Trying to get a replacement but no contact has been able to be made yet to return. Do not not buy near Chinese New Year. :) MY fault, not theirs. Would recommend if the newer units work OK.
I bought 4 of this for my rcrcm Typhoon 2m glider, 2 of them centers very well, while the 2 others could have been better. Due to a programming mistake I broke one, and I had to order 2 new servos. Luckely the 2 new 555MG centers well, and I'm happy with them. How ever, they buzz a bit, and the quality seems to vary, but they are strong, slim and easy to install, but you have to be careful while programming your flaps.
I have no trouble but my friend has a jitterning. We don't known a reason.

Perfect for ailerons in J class gliders. Fast, strong and reliable. I can honestly recommend those even for glass and carbon wings. If used for flaps can be easily demaged during landing. Thanks Hobbyking.
