Default JR servo spec misprint

Tennessee;

The servo specs on the 8450 package are a misprint.
(I have both)

The Correct specs are;

DZ8450: 98 oz/in @ 6.0v, .08 sec/60sec @ 6.0v

DZ8550: 188 oz/in @ 6.0v, 0.15 sec/60 @ 6.0v
and
DS8411: same specs when run on 6.0v (helicopter servo)

Man have I gone through the servos just trying to save money and it cost me more than when I bought a good one. I have had 2 Futaba S9450 servos on my car now for more than a year of racing with no problems. It has 8.0kg'cm of output torque with an operating speed of 0.10sec/60 degrees (6.0 volts). When I turn the wheel on my transmitter the car turns instantly and the same goes with the throttle. if you are lucky as I am you will never have to change a servo again. Just remember to set the limits on your transmitter so the servo doesn't bind because it is trying to push the wheels to far left or right and hitting the frame or front shock mounts. You will know when you hear the servo humming. If this happens back the turning limit down on the transmitter untill the humming stops and the wheels are not being pushed to hard left ot right. Don't forget to get a good servo saver.

both s9450 and s9550 are awesome....just see if you can get if cheaper than the other. check out Ebay first I saw someone selling it for $80.00 ...and also the the "Swap and Sell" forum.

I talked to Richard Saxton awhile ago and he said that the he runs the same servo in his 1/8 buggy and he always believed that the specs were right.
He told me he would look in to it on monday and get back later.
Thanks for the heads up on that,I'll contact Horizon also to get the real deal on that.

Are you going to be at the toys for tots race in december?

Tried them all- Can't go wrong with either Futaba or KO. I will never buy another Airtronics or Hitec servo. I might consider a JR though if it is not a digital servo.

Default Servos failing

I've had 2 JR: DZ8550 servos fail. JR service replaced them with new ones cost me -0-$$ each time.
One of my Hitec 5625 servos failed at the start of my Main in a big race one time (was TQ). They REPLACED a board inside under warranty.

Each time the turn around was about 2-3 weeks.

I have Friends that go through Airtronics servos like water and Airtronics is not so generous with their repairs.

I would buy something Digital that has at least a 1 year warrenty on it. (some have none)

The J.R. digitals have a 3 yr warranty.I'am not sure if the Futaba's have one.
I do know the airtronics have none that I'am aware of.
