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....</p>

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.
