Servos synchronization
 

Hey, maybe not exctly a RC question, but I hope you would be able to help me ;) Ive started a Stewart platform project recently and came across a problem with servos.

sorry for that crypto link, but I dont see another way of me posting a video as a new user ;/

They should be symmetrical in motion and although I control them at the same time I cannot achieve such a result. My guess is that it is because of poor quality analog servos which are Tower Pro SG5010.
Can u help me choose a propoer model of servo, so i can get the same, repetitive speed without a delay. I really need them synchronized. Thanks

Probably need to go with a programmable servo. Hyperion and Hitec both have servos with programmers. There may be more, these are the only ones I have used before.

Are you using a mix chanel or a sepperate servo reverse? I see one turing left and the other right. If so, you are sure it is the servo? OK, those cheap Towerpro servo's are crap but still you have to rule out other possibillity's
