Default Servo question... Specs Futaba/JR sport



I like the Futaba 3004's for a simple and cheap servo.
After searching a little, I thought I would give these JR Sport servos, ST47BB, a try because the specs said it had more torque and was faster. The price was very close to the Futaba's.

I recieved them today and I hooked up a Futaba and the JR Sport just to compare....... The Futaba seems to be faster, louder, but faster!??!?!?
Am I just crazy or are the specs wrong on these??

I bought these to go in my Twist 3D 60....

Specs say the JR is faster.

How did you check them? Maybe some kind of mix or trim on the JR channel?

I compared the "specs" area for each servo online..... JR is Supposed to be faster but the Futaba looks, sounds and is faster when I run them side by side.

When you tested them 'side by side', how did you do it? two separate channels? Y-connector? Could be something in the setup that makes the Futaba 'appear' faster.

Well, it wasn't scientific.... lol

I first did a Y and connected it to the Rx.
Then I did two different channels with them side by side and watched the movement.
Then I placed each one on the same channel and watched/listened seperately.

The Futaba looks faster no matter how I do it. Maybe it's just me!?!? No matter what, I'm going to use the JR's for my Twist 60.

I like the 3004 servos, good sevro forthe price ($11 from LHS). I lost one plane to a striped servo gear (not 3004), so I only use MG servos on the elevator in all my planes. Nothing like trying to fly without elevator controll! LOL

Yeah, I agree. I've got enough 3004's to do the plane but I bought the JR's so I'm gonna try them out.
