TR servo
I need some servo recommendations for the TR on my 60 nitro heli with a 6.0V battery and a 401 gyro. Do not want Futaba 9254 due to having to reduce the voltage. Looking for high speed (.06- .08sec/60degrees)
and moderate cost. Thanks!

I don't own the below servo so I can't recommend them based on experience; however, others seem to love them and they seem to meet your requirement for "reasonable cost". You will have to confirm the 401 will function with a 760us servo.

Isn't the 401 rated at 6.0 volts? Aren't you already looking at having to run a regulator for the gyro? Won't the gyro restrict you from running an unregulated LiPo/LiIon set up? Given the voltage restriction of the gyro, you could just run the 9254.

The 401 gyro is rated for 6.0 volts and I am using a 5 cell (NiMH) pack which is 6.0 v. The Futaba 9254 is rated for 4.8 v which would need a resistor added. Thanks for your input. More suggestions are welcomed.

You'd want a diode or two, not a resistor. I've had good luck using home-built voltage step downs with diodes with S9253/54 servos and other servos rated for 4.8V. I'm using Life 2s packs.-Kevin

Kst 525 is my choice for a tail servo. It's been great in a few birds. Otherwise promodeler is great too

Checked out the specs. on the KST 525. Sounds like a heck of a servo for the money. I have located one on Ebay, otherwise not easy to find. Many hobby shops do not even carry KST. Where do you get yours? Thanks!

I've got some from eBay, amain,buddyrc. Me and a buddy feel they are the best bang for buck servo we have used

I'm running the above mentioned Pro-Modeler servo in one of my heli's. Good solid servo for the money and you get awesome customer support from John.

nappyroots2182: Do you use KST servos on collective, cyclic, and throttle? If yes, which models (servo #)? Thanks!

Align DS655 is rated at 6.0v and is very fast. HOWEVER, I would always advise stepping down even a 6v rated servo when it is on the tail and none regulated (5 cell Ni-Mh can be around 7v fully charged) especially if it is a nitro or gasser. If you absolutely have to run 6v then look at a HV tail servo.60% of the time, it works every time!
