This is in reference to 1/8 scale off-road where we need the receiver battery to last through a 45-60 minute race sometimes. Do the digital servos suck up a lot more juice than a non-digital equivalent servo? I would also like to know if the hitec coreless servos (925 and 945 I think) center more precisely than the 645 and 605.

Hey! Yes the digital models use more power than the analog units, but is only about 5-10% more. I have 1100mah packs in both my gas truck and XR buggy and have no problem making one hour mains. I am using the 5925 for the truck and a 5945 for the buggy.

As a general rule of thumb a coreless will center better than a brushed servo, but its very hard to tell the difference. The most precise centering comes from the digital servos due to the fact they check their position 300 times a second vs 50 for a anolog unit. TTYL.

Thanks for the info. What other advantages are there to the digital servos? I'm currently using an Airtronics Caliber 3P to control. Do you think that a JR z4750 servo (plastic gears) will survive for a season in a 1/8 steering application?

More power, increased reliability, programmable features, coreless motors, more precise, more torq from center and a lot more holding power.

I would look at a metal gear digtal servo: HS-5925 or HS-5945..

1/8 scale, I would lean more towards the HS-5945..

Hope this helps....

So the analog 925 and 945 don't have coreless motors? What kind of programmable features do they have?

yes, they(925 & 945) have coreless motors also...

Programmable options include:

Speed
Dead Band
EPA
Rotation

just to name a few....

It does require the HFP-10 programmer to program.

I have a question is there another way to program those servos like with my PC because the programmer is priced a little high not to mention that i cant find it on line.

Unfortunately, no you can't. What we have done with the programmers is set up a deal with LHS's to purchase one and have it at the store to program servos for customers. Where do you live?? I can track down the nearest LHS that should have one for you. They are pricey, but a Pit Wizard is still selling for $80. When they first came out I remember those bad boys running $160 or more.

We'll try to track down an LHS for ya. TTYL.

thanks

Nova, we don't have any LHS's on our list that are from michigan, but try Larry's Performance R/C's in Sterling Heights. The number there is 810-997-4840. They may be able to give you a hand. Hope this helps a bit, TTYL.

thanks i will go see larry saturday.

First question - I had a 945 hi torque servo last year in my T-Maxx for racing. I ran a Trinity 6 volt receiver pack to it. Every servo saver I used on it, stripped out. It was like the splines were totally different from any servo saver I could find. And yes, I even counted the splines numerous times to make sure I had the right one. It would strip so easily that even after landing a jump, it would mess up the steering alignment. So, the real question is, what could have caused or prevented this? I got so bad, after 5 savers, that I ran an aluminum arm direct to the linkage just so I could finish a race.

Second question - I currently have a Lynx 3d w/spectra/novak combo and a 5945 servo ordered. That stuff was all on back order, but I noticed that my account was now charged for the full order amount. Does this mean that everything is in stock and ready to ship?

What servo savers were you using? I know you said it but were they for a 24 tooth spline? I find that the best ones on the market are from kimbrough.

As for an order, is the order from Hitec? TTYL.

I accidentally replied this message in. I put a seperate post on it. I've got the order details all straightened out. Showed up today. AWESOME RADIO! As for the servo saver, that will be an ongoing thing I think. I'll be running a 5945 this year. I have tried Kimbrough, GS, stock, and an HPI arm type. All stripped. And I counted teeth on the servo and the horns.
