Got surprised with a Protos for christmas

I am thinking of getting the Align 520 servos for cyclic. Are they going to have enough torque at 6V for hard 3D??

520 Specs:
Stall torque: 2.5kg.cm (6.0V) (this works out to 34.7 oz in)
Motion speed: 0.07sec/60 (6.0V)
Rating voltage: 4.8-6V

Decided on an Align 60 ESC. I have a spare 2100 gyro w/ 3400 servo. Does the 3400 have enough torque for the tail?

Will be using 6S batteries... running 2700 HS or so.

So what do you think? All feedback would be much appreciated.

The 520 servos MIGHT work, but they are pretty low on torque. More suited as a tail servo. I think those would be equal to when people were running 9257's on 6V on cyclic. The 510(?) might be a better choice, but it's slower. To give you a comparison, most people run 9650 or HS5245 with about 60 oz-in (4.4kg-cm).

The 3400 will be fine.

People used S9257's on the Trex500 so I guess it would work on the Protos

The 9650 are the heaviest servo you can put in the Protos

I'm using DS510's on cyclic in a protos
They are plenty fast enough as well as being stronger
and are very good quality servos (deadband=4)

I use DS520 on mine and they seem to work fine... I have about 30 flights on my protos with them and had them in my TREX 500 for about 40 flights. My flight style is stickbanging 3D

Im using the 520's as well, definately use them on 6v for the extra torque.
The speed is amazing.
Ive only had 4 flights on mine, with stick bangin tic tocs, flips and backwards loops.
Seem ok to me so far, but as I say, only 4 flights.
We'll see how they hold up in the long run.
To be cautious, go with the DS510's.
If you want the speed, go the 520's.
You can always use them as tail servo's on other 450/500 machines later anyway.

For the love of the hobby

Or you could use the JR Z3650's... I love mine! Lots of torque, and speed, plus metal gears!

I looked at those and the JR 3517s (which are pretty much the same servo performance wise)- they "are sweet". Both of these servos seem to be the very best servo you can get for the heli.

I just didn't want to spend that much money on servos. Got 2 DS520s for the same price as 1 Z3650. I only wish the 520s had metal gears - I know I am going to regret that on the first crash.

Do you guys really see the benefit of using .08 servos on cyclic?

I've used 9257s on the Protos (and later Atom), they are excellent cyclic servos. Fast, precise, and plenty strong. I would imagine that the 520s would be great as well, as the specs are similar.

Eury - Thanks for that feedback!! I know you know what you are doing... and that makes me feel better on having got them.

Are you running the 9257s at 4.8V or 6V?

9257s are rated at 27.76 oz-in @ 4.8V - so if you are running them at 4.8V... that makes me allot more comfortable with the 520s

9257's aren't rated at 6 volts, I run one one my tail, it's works great there at 4.8, I would think it would be risky to run it on your cyclic at more than the rated voltage, but I'm conservative when it comes to that kind of stuff.

I like them more because of the deadband, or lack thereof.

I've been running them at 6v since day 1. Haven't had a problem yet. I'm not using 6v for extra performance, I'm using 6v because that's what my ESC puts out. If you do a search, there's plenty of other people who have run 9257s on both 6v and 4.8v on cyclic successfully. Remember that there is a huge difference between 6v regulated, and a the 5 cell pack that a 6v servo rating refers to. Also, the 9257 is the same servo (aside from the gears) as the 9650, which is rated for 6v use.

Basically, I'm a pretty conservative guy, and I don't have any qualms about running 6v through a 9257.

Eury, thanks for the info, I've been running my whole system at 4.8 because of the tail, I may bump it up knowing that, just for the extra performance boost.

Thanks Eury!

I did notice that most of the guys running the 9257s on cyclic are doing so at 6V... and no one seemed to be having any problems with it.

I was wondering how much extra torque they are getting from the 9257 running them at 6V? No one seems sure on that... which is understandable.

If I do the un-scientific math

the 9257 rated at 27.76 oz-in divided by the 4.8(V) = 5.78 oz-in per volt

6(V) * 5.78 oz-in = 34.7 oz-in

The same as the DS520 at 6V.

I've got a question, is anyone running a 770 with a 9257 on the tail?

I have run the 770 w/ 9257. Once I moved the ball all the way out ( I know not popular) on star it locked in perfect for me. Really like the way it felt in 20+ mph winds backwards and motor loaded. This was on my Trex500. I bought a Spartan b/c it was lighter if you don't use the plate. It was easier to setup, but really not convinced that it is any better. Still thinking of putting my 770 back in. I left the ball all the way out and to be fair, I should move it in as instructed, but I"m having too much fun flying for testing right now
