Go to Bluebird directly and get a much lower price. In my opinion, this is a best in class servo. Although, it is slow. Bluebird makes this servo in several categories. This is actually old stock they are getting rid of for the replacement products already released. GO to Blue-bird-model.com and check out the full product line!! You will be pleased with their service also. Imagine excellent customer service. You won't get it at HK

Been beating the snot out of this thing in my Bad FLM Maxx for a couple months now and it is performing great. Fantastic for the price short term, hope it lasts because I really like it!

Initial impression is very good, seems very precise, smooth, quiet, and plenty of torque as a single servo in my E-Maxx Monster truck. I have only had one bash session with it so far but it felt good, and took the beating in stride. Hopefully it will hold up long term.

Excellent servo. Incredibly strong, quick, and quiet. Zero slop in the gear train. Beautifully crafted servo case and comes with excellent mounting hardware. Bluebird customer service is the best in the industry!

Sono rimasto molto sorpreso dalla qualit di questo servo,preciso e veloce,centraggio ottimo e pochissimo gioco agli ingranaggi,pi che gli ingranaggi un po il cuscinetto in testa all albero di attacco squadretta. Non sono rumorosi e spingono di brutto gia a 6v, li uso sul mio su26 50cc gasoline a 6v e aquesto prezzo con il motore brushless giapponese non ci sono paragoni. Aprendo la base per vedere le saldature sono di ottima fattura e paragonando a Savox brushless secondo me sono alla pari. Resta solo da vedere la durata ma essendo un brushless sicuramente sar pi di un coreless brushed. Poi da dire anche il bassissimo consumo con 26 kg a 6v circa 0.7ah normalmente,1.2ah sotto sforzo e circa 3.8 in stallo ma lo stallo di 26kg vi porta via le parti mobili del modello..figuriamoci 30 31kg. Questi assorbimenti li ho su di un servo da 10-12 kg digitale savox. Insomma devo dire che sono molto soddisfatto dell acquisto e vi consiglio di farci un pensiero magari su di un modello da allenamento tanto per vedere la durata e la qualit spendendo la met!

Bought one of these for my comp shafty crawler.
Nice packaging and sturdy horn set.Well finished overall,nice fittings included with a couple of decal sheets too.Plenty of torque even on 6v with very very little slop at rest.Perfect centering and quieter than a Savox at a lot less money.
I have to agree with the previous review,dont hold back top quality item at the right price.Delivered at less than 56.
Only 4 stars for quality as the plug had some very minor flashing that allowed the signal pin to push out on first connection-something and nothing i know but all the same,had i paid the full 122 i would not have been happy.
Recommended 100pcnt.

do not hesitate to purchase this servo. half the price of a savox and just as good spec. the build quality is second to non and with a torque of 31 kilos you cant go wrong. i have 3 for swash in my Sab Goblin 700. rock tight. no swash movement even when not powered on. btw for all flybarless stuff the frequency is 333 HZ.

Super Servo!!! Habe 2 stk. auf Hhe ( eins je Ruder) bei meiner 3m Extra.

Super Mittelstellung, fast kein spiel und sau stark!!!

Qualitativ sehr hochwertig. Voll-Alu Gehuse, sieht echt edel aus.

Das Zubehr ist auch erstklassig. Ich betreibe sie mit den Futaba Alu-Hebel lang. Passen genau und sind wie dafr gemacht.

Super Teil!
