Title: Servo's?
Post by: Mark_NC on November 19, 2016, 12:37:51 PM: Looking at getting a 766... any recommendation on good servos? Any I should stay away from? I am a sport-flyer, and this will be an upgrade from my 500...

You just can't go wrong with futaba. I am using the BLS275SV and I absolutely love them. They are pricey but well worth the investment.

I have trust issues with servos. Especially when you have so much invested in your 766 :)

They get great reviews with some other big heli's and they are on-sale (slightly!) at AMainHobbies :)

I myself have not had this issue, I have however spoke with guys who have. they will shutdown in flight if you ask too much from them and you lose a servo.

Yikes! I ordered them a day or two ago... Hopefully will be fine. I am more a sport-flyer than 3D so should be okay - at least that is what I will tell myself!

JR 8717 and 3717 for cyclic and throttle and NXB89G for all the tails. If you need the baddest cyclics available I go with JR NX8935

I read somewhere that he "load/stress" on a servo increases as the operation frequency increases. These Xpert's can run at 400Hz. Should I maybe run them lower just incase? Is there a lot of difference in cyclic response if you use 50Hz vs. 200Hz. vs. 400Hz?
