I ran a 357 for steering all season last year, and it would never center perfectly. When setting it up on a Hudy station you might as well forget about getting an acurate toe in/out reading, ect., but other than that it functioned perfectly. I ran a 737 for throttle/brake and that worked perfectly also. I talked with one of the sponsered drivers at our local track and he told me the same thing, and he too was at one time sponsered by Airtronics (JR now). I am not bashing Airtronics, they make some of the best electronic gear around, and you would never go wrong with buying anything they make, I'm just agreeing with you guys.

Don't feel bad guys ,I've had every type Hitec servo they make. I know Hitec not the best, but kinda affordable, I went to digital servos last year hoping to cure the centering issues. I had to buy a $200 programmer to cure the problems even with the digital stuff. But I can say it does center perfect now!

hey bb..I use all the hitec digitals also(9 series)..
and also have the programmer.(just haven't tried it yet)

how did that help the centering?...thanks..

I've used several different JR 8450 digital servos in various RC vehicles. Every one centered perfectly. If you need a servo that works perfect, check out the JR8450.

They just don't center perfectly like nut said. I've sent them in a number of times to get fixed and they come back the same. They work fine and until something came out that did center better I didn't really have much of an issue with it. Now I just run the 758 and it's still not an issue... for some people they center just fine. For my personal taste I like it to be more precise... that's all.

Shiloh, I think you 100% right on the Jr.'s, I think they make the best servo on the market for the past few years. My 5925 Hitec's are very smooth but the JR digi is even smoother.
Harry: You can reprogram the center point on the servos to where ever it seems to center best at and then reset all the linkage. I have never used mine either as of yet. I have an Airplane buddy that uses all Hitec gear and he programmed mine when I installed them.. The new Hitec radio has a finer trim adjustment now that they say helps center much better than the old Lynx 3d.
I have a Hitec lynx 3d with spectra and have never had any trouble with that ugly thing for 3 years now. But. I have layed it to rest for the new Futaba 3PK.

since gears are round,and the motors are coreless,I don't quite get how moving the center line will position them different and help them center..but I'll have to break that thing out and give it a try..


BTW,that 3 pk is the cats (butt)..I have one..

Glad to here about the Jr8450, since I picked up a used one and have not put it in any of my cars yet. I just tested it out of the car and it felt good. I still need another digital for my 3pk with the hrs receiver. Funny thing though. I have all these great features on the radio, but hardly used any since I am so used to driving without them. My goal is to expirement with the radio this weekend.

Harry, I have been having a centering problem with my airtronics 347, but it turned out to be that my ball cups were rubbing the steering rack. I have been driving the car like that since changeing to the rpm cups over the winter. I put back the AE ones back on and presto, problem gone. I had shaved the rpms, but I guess not enough

hey all I was wondering what manufactures mean when they state that eh servo is coreless?

Thanks Jason

Try it Harry you might be surprised. It sure helped mine. My bud flys heli's and planes and he swears by the programmer. I understand where you coming from on theory, but???
Maybe ask it in the Hitec forum, Mike will answer it.

That servo is brand new I only ran it twice and it won't center after turning left. I have a Hitec HS-5925MG in my TC3 so I put that in this weekend and that made a world of difference. I think I am going to stick with Hitec because I have them in all my other cars as well and have been happy.

bbntc3 How do you like that programmer? Is it easy to use I have been thinking of getting one myself.

I've really been loving the Futaba S9550 servos. I have them in both my Losi electric sedans and now in my Nitro TC3 as well. If memory serves, they are .11 sec with 83 oz. of torque. There are beefier servos out there for sure, but nothing beats the low profile (the case is about 3/5 the size of a standard servo) and light weight.

Used to race @ Castle a couple of years back. Just got to be too many people and clashing egos down there, so I took a break. Ran up at Delta a lot (esp. off-road). Now I am checking out Lemans RC over in Fremont.
