What are the best cyclic servos for my T-Rex 600n? Fastest, most torque? Brushless? I'm a Futaba guy so would prefer to use Futaba servos. Any suggestions??

Thanks

Peter

And some people are running the 8717s on straight 2S lipo, at 8.4 volts. Even FASTER.

I have Hitec 6965HB servos on my cyclic.

.08 seconds and 111oz at 6 volts. About 80 bucks each. IMO the best speed and torque for the $, but 8717s are the ultimate servo right now especially if you run them on a straight 2-cell lipo.

I have Hitech HS-5625's on my 600N sport and Futaba 9252's on my 600E CF. I bought another 600E GF and I'm putting in HS-5625's in that one, and I'm looking at another 600N pro and I'm looking at the Hitech HS-5965's for that one, as I am still noob enough to need metal gears, but don't want to spend $109 ea for servos for the JR. Then again the Hitechs are $72.99 ea for the 5965's. The 5625's are quite a steal IMO at $46.99 and the one's on my 600N sport seem very good and plenty fast for me :).

5625 is a great servo. I used to have several of them in my planks.

The 9452s are plenty fast for me and were a good compromise between speed and cost.

Wait how do I run JR8717 straight from the lipo? So no regulator?

Just connect the LiPo directly to your reciever, and then the servos directly in to the reciever, works great with AR7000 here:)
