hey guys what are the pros and cons of digital or not. i was looking for an airtronics 94358 but none on ebay. so i saw the hitec 5945 (digital) and the airtronics 94359z (digital). i run with a venom 1100 mah nimh flat pack, and am currently running with the stock t maxx tx and rx. would i have to change that rto run a digital servo.

Digital servos allow for some additional programming if you have the right equipment. They also tend to be stronger, faster, and have better/accurate reactions to transmitted inputs. Also, they tend to be better at recentering. So far, the only negative thing that I have been able to find on them is the fact that they tend to be a bigger power drain on the batteries. You might also consider their cost as a negative, but I have found them to be both worth the price and competitively priced.

If you are going to go this route, most people recommend getting a rechargeable battery pack for the receiver. I personally have run with both rechargeables and dry cells. I have not noticed any major difference in the performance between the two.

Just so you know - the Airt. 94359z is *not* a digital servo.

Hitec 5945s are good product. Strong & fast, more so if you're using a 5-cell pack. Good gear life, too.

Either servo can be used with the stock Traxxas tx and rx.
 
i went ahead and bought the airtronics 94358 servo. i was just wondering should i get a new servo saver or just use the stock, and if so what have you guys used that has worked well for you. i was looking into getting the proline steering kit what about your expierences with it? how much friction does it actually help eliminate?
 
Servo savers are not for reducing friction. The ProLine steering kit is a buggy style servo saver built into a rather beefy steering kit. It is an excellent upgrade. You can run that set up without a servo saver on the servo.

As for what servo saver to get in the case that you do not buy the ProLie kit, I recommend the Kimbrough brand for a servo saver. CLICK HERE for one found on Tower Hobbies.
 
what exactly does a servo saver do? How does it work?


--NooP
 
It makes a link that is moveable in your steering. Basically a very stiff spring so it will still turn the wheels but at the same time, if you hit something landing a jump that forces your wheels the other way, the spring will take the impact instead of your servo gears. That way you don't destroy a servo.
 
Do you have to have special equip[ment to run digital servos? I have the hs645mg but it never re-centers good. How does the hitec 5945 perform?

Hey Sweetmaxx, I think your first question/s where answered above. I would highly reco the use of a 5-cell NICAd or better a NIMH pack with the use of 1 Digi servo and IMO a rechargable pack is a must with the use of two or more DIgi servos. THey drain ALLOT more power then comporable standard servos. I run the 5645 in my maxx and I love it (the best $54 I've spent on my truck so far). I run 5-cell 2700 sanyo pack and yeah it might be a little overkill but it delivers full power to my Steering servo and gives me long ass run times between charges.

As for your 645 and possible centering issues. I know lots of RC gurus that run that servo and most love it. It should center perfect....it may be defective or you may have a problem with the gears. Is it making an excessive humming noise?? You may need to take of the top cover and center it yourself.

CIAO
 
Sorry for not being clearer. I already have a rechargable pack but i heard that you need special receivers and radios for the digital servos. I'm guessing this accusation is false?

Absolutely it is.....Like SKymaxx and other pointed out. If you want to realize the full benefits and features of Digi servos like "Failsafe" you need a servo programmer. You don't need a special reciever or radio to relaize the other BIG benifits of Digi servos like SERIOUSLY increased speed/instintanious response and power.

Peace
 
CLICK HERE to view a HiTec programmer from Tower Hobbies.

The programmer basically allows you to troubleshoot servo issues. It also allows you to program endpoints, turn on fail safe modes, and numerous other digital servo related capabilities.

Noop, the servo saver acts as a shock absorber for your steering servo. Properly installed, the servo saver should absorb any jolts to the steering linkage so that your servo does not have to suck up the jolt.
