Default JR Servos for the 8ight?

got an 8ight and i need servos. i have always sworn by JR servos and i'm not going to switch brands now. so.....i'm thinking z4800t coreless (162 oz/.16 sec) or the dz8800t digital (188 oz/.15) for throttle......and a dz9000s digital (128 oz/.06 sec) for steering. is 128 oz enough for the 8ight, or would the stronger but slower dz9000t (320 oz/.15 sec) at 320 oz be the better choice?

what jr servos do you guys run, and why. what's your recommendations? thanks.

I was running Z650s on both steering and throttle. The throttle was an old steering servo, got worn out and developed enough play to twitch real bad when it tried to center itself. For a temp throttle, I have a standard BB(like 50 or 60 oz). It'll be fine for now, but the point I'm trying to make is 130-160 is plenty for steering. I'd go with the faster digi on steering, and even the lowly Z650 will handle the throttle with ease...

Nar JR and KO are totally different.

Im using JR's 8455 for throttle and 8715 for steering. The 8715 is a new release and has 12kg of torque and .09/60deg @ 4.8v. Lightning fast and huge torque. The part numbers I have might be different to whats available in the states, cos I'm an Aussie.

For an 8th scale or a Truggy go with torque servos. We have been running 9000Ts in my sons stuff since before they were available and have had zero issues with them.To me having strong servos that will turn well under load and have great holding power are much more important for the bigger vehicles than the speed.

I've been using 8800s and 9000s in both my Mayhem/Turmoil and my Truggy for steering and they work very well. The nice thing with both of those servos is the fact that they are fast, AND they have gobs of power too. If you wanted to concerve some receiver pack juice, I know people have used the 4800S on the throttle/brake side too.

That's exactly what's going in my 8ight. I used an older JR 8450 (~120oz/in) to steer my Jammin car for the last 2 seasons, it worked fine and it still works to this day. gasser makes a good point tho - the heavier cars will benefit from having strong servos that always turn under load and have great holding power. Ya can't go wrong with JR servo's
