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
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.
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
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
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...
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.
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
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.
