Digital vs. Standard servo current draw

Digital vs. Standard servo current draw
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.

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....

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.

2 ? Bad splines? Ordering/Payment info?
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?

wrong thread
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.
