Perfect for use on my HK550 and HK600 on my Turnigy and RotorStar standard size servos. Very strong and fits perfect.
holes are 21mm and 24mm from center.
ByeI purchased these for my T-REX 550 (Align servos). They do fit the servo spline, but they are to lose to be reliable. They do not fit the spline tightly. They may fit other servo splines tightly, but not Align servos.Solid arms. Came with all required parts. A bit more bling but not necessary as its hidden by canopy.I'm using them on my Rex550 with Align 610 (I guess they should work on futaba as well - same spline). They are robust (haven't broken them yet) and have a nice finish - one of my better upgrades.nice metal arms and cheap at the price, but if only they had a selection of pre tapped and drilled holes - then they would have been sooo much more versatile and useful in lots of different applications, think the marketing boys missed a trick there..nice finish but too much space between tooth of servo (HD 4180BB, 3F Standard Spline (25 tooth)) and armVery nice quality! Good for all Futaba servos!
Nice colour.These fit the standard size futaba servos and look great and give plenty of throw on my extra 330s 3D 90 size nitro.Hi , servos Align, Futaba, holes M2, long 31 mm, all this parts are very good made .I am very happy with them . From Hong Kong in Irelan post take just 7 days with no prob. at all .
