JR XS3 + HS-5945MG (high torque digital steering servo) ?

[RobH]

I got my HS-5945MG from the men in brown today. I'm a little concerned especially after reading the insert.

I did a search on it and I didn't come up with much. :\

1.) Will this digital servo work with the JR XS-3 reciever?

I'm assuming if you can run digital and analog servos in some digital reviever, I should be able to run this digital servo in my reciever which may or may not be digital. I'm thinking it's not digital. The XS3 is good but better radios exist.

2.) Digital servos are battery suckers. What battery setup manditory to make it work?

Right now, I'm running standard 1.5 AA batteries in my reciever. Must I spend $60-$80 on a 6v hump pack & charger? a guy at my track uses a 7.2v hump pack. if i go that way, i may bump up to 7.2v for the hell of it. (unless you guys know of a problem with that?)

What about the expensive "Lithium" AA batteries you see? no good?

I have no problem changing my batteries everytime I go to the track. It's only like 20-30min of total run time.

don't get me wrong, i'd like to grab a hump pack someday, just not right after paying for the $80 servo.

3.) What about this Y-connecter bullshit? Sometimes you have to bybass the "BEC" component in the reciever? Do I have to worry about that with the XS3's reciever? or can i just power the reciever normally?

thanks in advance for any help you guys can give me.

you have to love it when, you have to answer your own questions. for the benifit of the search function:

1.) Yes, the HS-5945MG works great with the XS3 reciever.

After installing it, I could feel the quicker steering response. Every motion of the wheel is mimiced perfectly by the car's steering. I can make my buggy do mad fish tails by swining the wheel from side to side. If I'm not careful, I can flip it over even.

2.) normal 1.5 AA batteries in the reciever pack work great. i'm not sure how long they last, but as long as I can make it through race day, I'm fine. i need to buy a hump pack some day but this reciver / servo combination doesn't require it.

3.) The XS3 DOES have a Battery Eliminator Circuit (BEC) and if you don't use the y-connector set up, it wont work correctly.

I ran the servo without the y-connector and it seemed like the servo would just stop responding at times. I switched over to the y-connector (same set of batteries) and the problem went away. it now works perfectly.

Y CONNECTOR SETUP:

you plug the battery pack into one side of the y connector. then you plug the servo into the other side of the y connector (both of these connector's are female on the Y). you take the only male connector on the Y and plug it into the reciever where you would normally plug in the steering servo. This conficguration gives power directly to the steering servo and bypasses the reciever. the reciever does not need a direct connection to the reciever battery pack as it will now recieve it's power via the steering servo control wire.

that's probably clear as mud, but if you buy one of these servos, you'll see the diagram in the instructions and understand how to do it.

Thanks for the info Rob. Did that Y connector come with the digital servo or did you have to purchase that separately?

I never had a problem running a digital servo in a standard receiver.

i had to buy it seperately. i did have to modify the power plug i think (the dremel is a great tool).

you should pay special attention to the black and red power wires. you don't want to accidently invert the negavie and the positive wires (will fry stuff most likely). just make sure you match black to black and red to red and you'll be fine.

yep, I found that out the long way.
