Nice looking but after 80 flights with my HK 550 FBL these servo arms are not tight enough in the teeth. There is a big gap and the arms are useless.
Alu material is extremely soft. Not good product at all.

Installed on my T-Rex 550e, they finish it off nicely and i'm much happier using these as opposed to the originally supplied plastic one.

ciao



ottimi, perfetti per servi montati su servi align ds610



la linea e i colori ricordano molto quella dei bracci trascinatori della testa fbl orginale align ( del trex 550 e 600)



consigliatissimi, molto molto pi rigidi degli align in plastica



ciao ciao

Align DS510 DS520, DS610 & DS620 all have the same size spline & count. I put these on my DS510 to check for fitness and found there is a slight play. I hope its a better fit for the Turnigy 1258TG servo

Quality is really okay. I like the metal arms. Very stable and a good value for the money.

Ordered a couple of sets for my new HK-550 TT FBL and an other heli. Bit disapointed here as I had hoped that they would fit the three Turnigy 1257TG servo's that I built in. Unfortunately they don't. They do fit but you have about 2 mm play.

Fitted to my T Rex 550e on Align servos. Price and quality cant be beaten, even the shipping from HK to Austria was quite quick this time at 9 days.
