Purchased these for the TGY-930 for a knock around 500,as other reviewers said they fit.the ones that arrived are unusable on this particular servo as there is to much clearance between the splines causing play which under load will at some time strip.Arms was used on MG930 and hks 9257 and they have too many backlash. I replace it by arm by align d5af.Good price and decent quality. Cyclic servo arms are a bit sharp around the edges and the finish is a little rough, Ball links are included which is a plus. Rudder servo wheel looks really nice. I would recommend this part.Price / quality ratio is very good I recommend Daniel!I haven't flown with them yet, but they fit the TGY-930 pretty good. Longer output arms than the stock TGY-930 servo arms. Couldn't be happier!
They also look 10x better than they do in the picture.Very nice arms and disc. As others have said though, these are not ideal if learning and crashing as all shocks will pass to your servos. Great otherwise.These are fantastic, fit the mg930s a treat and look good too. Would definately recommend just to get rid of those hideous plastic arms. Remove the balls and threadlock though as only finger tight
