I purchased a HS5735MG and it failed after 10 minutes on the bench, and it was quickly replaced by Hitec under warranty, no big deal. I now just had another Hitec servo model HS5945MG digital 100$ servo fail after 3 months of mild operation. I need the address to Hitec warranty department for round number 2 please.

I have no doubt they will replace this one also, but that isnt the point now, I am now waiting on parts for time #2. I would spend 200$ for a servo that would last longer than 3 months under a practically no load condition.

I will not purchase anymore Hitec servos, as I see the high end type fail multiple times under a one year warranty period. What happens when the warranty expires?

I don't think so, TODD. Take a look at this.

Not sure why your servo failed, but if you think JR servos will hold up longer your in for a rude awakening...

There are many reasons these servos fail, generally it's the application and or set-up. Incorrect ATV or end-point settings, lack of vibration isolation and such.

The 5735 is a not a high end servo by most standards as it uses a standard motor verses a coreless motor, although is does use a digital amplifier. These have proven to be exceptional servos.
we've been using these since they were first released, never a problem.

The 5945 has also proven to be an exceptional servo. I/we have yet to have a failure with these servos. I have over a hundred of them in service, none of them have ever needed service. I can't say that about JR's 8411's.

It's possible you got a bad one and or it's possible you overlooked something in the installation and or the setup. All things fail, even the best products have a failure rates.

Hitec warranty is 3 years, I believe.. Worry not about Hitec taking care of you. Hitec will bend over backwards to make you happy.

I had started with one 5735 and 2 5945. I have but one 5945 that hasnt crapped out. Of the 3 servos I have 2 of the 3 have failed.

I have a JR-R1 Radio and am very capapable of setting end-point adjustment , servo throw, ETC. The Failure isnt because of my in-ability to set my radio up correctly. I am using it in a 1/5th scale car.

If you guys have 100+ 5945 without a single failure- get ready for #1, think if this had been in a 40% plane fellas.

By the way the 1/5th scale that I was using this 5945 in was used for less than a half gallon of gas, since the servo was brand new. Also, it was only being used as a front disk brake supplement, and was only actuated upon brake application, which happens rarely in a 1/5th scale, do to the excellent engine brake of the 23CC 2 cycle engine. So my only point is that it was being used in a VERY mild application, far from keeping a wing surface in place for extended amounts of time such as in a 40% plane application.

The 100 plus Hitec 5945, 5925 and 5735's are in 33 and 40% models. Been using them for two years or better. Did the same with the other's too many failures, moved on to servos that haven't failed thus far. I also like the ability to program the servos for the application.

Who know's, these are simply mine and other's experiences yours may vary.

is that address to the warranty dept.?

The servo that failed is the one on the right, in this picture. It was set up on channel 3 (front disk brake) which was mixxed with channel 2 (throttle/rear disk brake). at 88% of ch. 2's 100% full range. Sub trims are all at 0. ch 1 is set at the middle on the main trim, the steering is at 4 clicks to the right. Travel adjust on the steering is:L=85% R=78% throttle F=73% B92%. Channels 1&2 are reversed, and channel 3 (aux) is in the normal position. I am using the SPCM modulation.

Anyone see any red flags as to possible problems with my setup?

Todd- Sorry to hear about the problems. The Hitec service info is posted at the top of this forum http://www.rcuniverse.com/forum/tm.asp?m=364127

Here is my take on this as I have experience in 1/5th scale as well as all other types of R/C cars and racing. A 22 pound car going 60mph+ takes a lot of braking power. Sometime the load on the servos is so much that their life is greatly reduced. The digital servos do have more holding power but they also draw more current. In 1/8th scale on-road where speed and traction are at their highest the standard coreless servos are lasting up to two seasons, but when people started switching to the digital versions from any manufacturer, 3 months was about it. In that class now almost everyone just runs coreless (non-digital) only. This is what we currently recommend for throttle and brakes in all gas and nitro applications.

Hitec is looking into ways to make the digital servos more durable for throttle and brake use in the larger size cars like 1/8th and 1/5th and hope to have a new line of digitals out in the future specifically for that market.

Mike..

Is it ok to use a 5945 for steering in a 1/8th buggy?

What servo would you recommend to replace the 5945? I am not familiar with non-digitals with comparable specs. Also understanding I am running a 25pound model 60+MPH and it has to be as safe as possible. To have a front brake servo failure at 50MPH would almost certainly result in major damage to my car, at the least, and anyone around it at the time at the most.

Todd- The digital servos are holding up well in 1/8th off-road steering because there is not as much traction as 1/8th on-road. Our team driver Gene Hickerson used 5945's in his 1/8th buggy to finish 13th at the IFMAR World Championships in 2002.

I would use the 945's http://www.hitecrcd.com/Servos/hs945.htm for throttle and brake in your 1/5th scale race car. The 5735 is still OK for the steering, they have been holding up well.

Mike.

[QUOTE]To what "dont think so" are you refering? [/QUOTE]

[QUOTE]What happens when the warranty expires? Yep, you are correct! YOUR SCREWED. bYE bYE HITEC, hello JR. Your turn.[/QUOTE]

[QUOTE]The singular most important practice of the Hitec service department is the fact that posession of a receipt does not seem to be a major issue with them even for warranty work. [/QUOTE]
[QUOTE]I cannot count the times I have been stiffed on legit warranty work merely because life is to short and to much flying time is wasted being a meticulous records keeper, Lets not even talk about those idiotic warranty registration cards (the only purpose of which is to provide free demographic info to the company) that have so often been used as an excuse by some companys. I have delt with most of the majors since Orbit and your service department has been the key to your success. [/QUOTE]

[QUOTE]All of my repairs have been because of crashes--every time I send the equipment in I give my credit card number and ask you to charge me. [/QUOTE] [QUOTE]So far I have not been charged, as a result of the good service I buy only Hitec servos and receivers[/QUOTE]
