Having used both I like the 9257 better. If your running 6V system you will need a drop down regulator for this servo but even at 4.8volt its faster than the 9650 at 6 volt.

If you've done the tail mod the 9257 is a great choice. Without the tail mod I'm guessing the stronger 9650 is actually faster in use because of the torque it has to overcome. I have used both servos on mod'd and unmod'd tails. You don't have to have the mod but it makes both servos work better.

There is a very fine line between "hobby" and "mental illness."

Having used both the 9257 better and you don't need any modes.

hi

Ive used 9257 on 4.8 V and JR 3400 on 6V.. the 3400 is MUCH better... having said that.. If you want to stay on 4.8 or use step down regulator, 9257 is awesome.

Just my .02$

Crash-Prone and overcoming it!!!

Anybody burn up one yet without a step down reg?

Why would anyone even consider a 9650 or 9257 when the 3400G is out there? The specs are better, and it can be found within $10 of the price of the Futabas. Plus, it's rated at 6v. Honestly, why would you choose a 9257 or 9650?

Simple, look at the specs versus the 2 Futabas, I always buy Futaba servos, but in this case, I think the 3400G is superior:

9650:

4.8V 50.0 oz-in. 0.14 sec/60°
6.0V 62.5 oz-in. 0.11 sec/60°

9257:

4.8v 27.8 oz-in. 0.08 sec/60°
6v not supported

3400g

4.8v 42 oz/in .11 sec 60-deg
6.0v 51 oz/in .09 sec 60 deg

It has nearly the strength of the 9650 with nearly the speed of the 9257. It's the perfect compromise, and no step down needed like the 9257. I just know that I've had the 9650 (when looking this last time it was between the 9257 and the 3400g), and the 3400g holds better. Tailslides with my 9650 would blow out, they are solid with the 3400g, both with 401s. The 9650 was a great servo, don't get me wrong, but I'm happier with the 3400G.

Oh!
I've been running a LTG2100T/9257 on 5.5v.
At 4.8v the 9257 is still faster.
So why did you buy JR?

Because of the torque and the support for 6v. I'm also now running the 2100T, which supports 6v, and I can't make the tail let go with that setup. I also like that I don't have to run any kind of step down. When I was putting together my 450SEv2 a few months back, I looked at them all, and the 3400G just made the most sense, nearly twice the torque of the 9257, with nearly the same speed, and it'd take the 6v that my ESC's BEC puts out with no problem.

Speed is nothing without sufficient torque to muscle it through the applied forces - A fast weak servo can be slower than a strong slow servo - The 9257 looks marginal on torque to me so I wouldn't doubt the 3400 outperforming it - But boss weighting could give a fast weak servo advantage by removing a considerable amount of load off it

6V not wanting to step down there's no question about going with the 3400 - An alternative to the 3400 might be the HS-5082 due out Feb? for about $35
4.8V 38 in-oz 0.11 sec
6.0V 47 in-oz 0.09 sec

I was thinking that as well on the 9257 when I was comparing them.

If you have the tail mod there is no concern with the lesser torque of the 9257, even without the tail mod it is great. The 9257 is definitely superior to the 9650 with the speed...having both the 3400 and the 9257, the 9257 is faster on 4.8V than the 3400 is on 6V! Also weighs a little less than the 3400. It just comes down to a matter of preference.

9257 vs 9650

Ill be switching out my 9650 today at work, for a 9257, and will be trying it. I will post what I find out about this servo

Currently I dont have the tail mod on, and I need to put it back on eventually, getting lazy and not wanting to mess with it

Jason Chow is running the 9257 with a stock tail, and he loves it, that and i've never seen him blow out the tail

9257

Flew the 9257 a bit earlier, and its pretty awesome. The tail feels alot more crisp, most likely due to the fast speed. Really happy with it

If the 9256 only has 48 0z-in. of torque and it is fine for a ninety sized helicopter, why does the t-rex need a servo that actually has more torque than the 9256?
