Just curious if the people running these servos have any opinion on them...the good,the bad,or the ugly.Going in a 40% Cap....you think it will be OK??

40% Cap.hmmm... Yes they'll be good for everything. If you are planning to be very aggressive with 3D moves and such, I would personally put the 5945's on the ailerons and the elevators and rudder with some 5995's. Just my 2 cents.

boy you are about to open one gigantic can of worms! There are definitely schools of thought on these servos...I for one will never have another in any plane I own. I know personally of several others that have lost planes due to failures of this particular servo and Hitec claims that there are no problems. It's your money but my $$$$ is spent on either JR8611s or Futaba 9152's. The 8611's have proven to very strong and reliable and the Futaba looks to be the same if not better (it's a physically bigger servo and may not work in all planes). The 5945 is certainly strong enough to do the job but I personally just won't risk my high dollar planes to Hitec. Others have had good luck.

There is absolutely nothing wrong with these servos, if they are installed properly.
For 40% though, I would look at the 5995's . Two for ailerons would be overkill, but good, one only on each elevator halves and for rudder, look at the Seiko servo. with 1800 oz of torque, That is what I have on my 52% Edge.

yeah i know,,i dont want no battles going on..these servos came with the plane...i think i can handle them on the ailerons...but not on the elevators...there are 4 ganged for the rudder...but i am thinking 3 8611's...

They work fine in my 40% planes. I have 1 5945 on each elevator also.

While I said before that many people have had good luck using them....but be aware that there is a disproportional amount of reports of "hardovers" with these things. WITHOUT FAIL hitec reps and supporters automatically blame the user claiming he has no idea how install or setup a servo...and GOD FORBID it was on a ganged setup! Oh my GOD! Naturally nobody knows how to "properly setup" a ganged installation..."it has to be the fault of the user". If you had a failure do not expect anything but "what did you do wrong" from the reps and supporters beecause they "have never heard of that happening before". Hitec is great about replacing bad servos....they should be pros at it by now....but that does nothing for your $5000-$7000 plane that is now splinters. They can claim whatever they want but do yourself a favor and do a simple search for "Hitec failure", than do one for "JR failure"...and than do one for "Futaba failure". You can of course substitute 8411 or 8611 for JR...but read the threads! If you actually take the time you are goin to see that even in the JR theads the word failure is most often describing a Hitec servo. I am not making this up......just do yourself a favor and check for yourself. It makes no sense to me to risk a $5000+ airplane to save $150 total to use Hitec gear. If it still seems like a good idea I wish you the best and hope that you have a positive experience and enjoy your plane for many years to come. But do it with your eyes open! They have a reputation for a reason...just like JR8411's had a rep for wearing out gears quickly and "pulsing"...it is true! But you rarely heard about them being the cause of a crash! Naturally you can always find an example but it's rare. The 5945s will be adaquate if you gang enough of them together powerwise and the gears seem to hold up well enough......it's just the reliability factor that makes many of us say "not in my plane".

I am sure all the hitec supporters are gonna go crazy on me here so I am gonna not post to this thread again about this.....just do your OWN research and draw your own conclusions. Not mine or anybody else. Good luck with your project.

Leardriver

xtra, just make sure you use good extentions and that you have good connections. With these precautions they seem to hold up as good as any other brand. If you get a loose connection you can expect weird things to happen.

On my 33% Cap, I replaced the JR 8411's with Hitec 5945's all around. This allowed me to remove all Matchboxes, thereby removing extra sources of potential problems. With careful programming of these servos, they end up perfectly matched. I since had hundreds of flights with no problem until last week-end when the engine quit in a torque roll, and I lost the plane. These same 5945's will go in my new 33% Extra. They are great servos. I am not prejudiced: I have Futaba 9152 in another GS plane.

Hundreds of flights over many years, never lost one yet!

Do a search here on RCU.. then see what you think.. Like leardriver, I wont touch them either. Personal preference from all the crashes Ive read about here and in my own club.

SO, that said, I personally go JR, then futaba. 8611 is an awesome servo, with 14 of them in my Yak Im very happy.

For the record...a little birdie whispered in my ear that JR is soon to release the 8711! 330oz torque at 6v and it is utilizing the same size case as the 8611. If it is anything like the 8611 it will be a winner! I bet Futaba has by years end as well.

Leardriver

Jeez! GO JR!

Jr.

epc.

I have 8 of them and they work fine.
As with any metal gear servo, the gears wear out.
I would also make sure that your wiring can handle the current.
I found that I had to change some of my wiring to improve power distribution through-out the whole plane.

I've got the Hitec 5945 servos in a Wildhare Extra with 200+ flights, before that about 350 flights in a H9 Cap. One servo failed with stripped gears on the aileron after more than 400 flights. No other problems.

I'm not anti JR or Futaba etc. I've had good luck running my hitecs, and futabas and jrs. I've had futaba and airtronics fail. It ticks me off though when there is misinformation used to slam something. It seems that the servos that 'failed' were in a prior airframe then not sent back but used in a second airframe where the incident occurred. Here is a quote from Marc, the RCU admin, to another individual concerning some of the so called hitec failures.....

http://www.rcuniverse.com/forum/m_22...tm.htm#2275095

I have 42 of these servos in my planes.... flawless, tight, and trouble free.

I use an H9 ammeter when doing setups and I don't use previously crashed servos .. that may explain why I don't have problems and some others on this post have...


Use them with confidence... just make sure they are programmed correcty and that the current is zero or near it at all end points.. of course you would do this with JRs too (I hope)....


I am amazed at how emotional some people get over this stuff... JR, FUT, HItec... its all good man!

DP

It is amazing how people can misconstrue events when they were not there! I am not even going to address the crashed servo comment because the thought that I would use a "crash damaged" servo in a $4000 plane is just rediculas! The servos in question...in my case.....were in a composite airplane that had what amounted to a dead stick landing in the rough that resulted in a broke fuse around the gear plate. Because it was composite it was not feasible to repair. The back half and the servos were untouched! BUT MY OPINION IS NOT BASED ON ONE ISOLATED INCIDENT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!! <-----GO BACK AND READ AGAIN!!!!!!!!!!!

Since we are going to do this...again.......I know of at least three planes locally destroyed directly due to these hitec 5945 servos!!!!! in one case a guy lost two planes over the summer (a 2.6 comp-arf with an elevator hard over and a Dave patrick edge with a rudder hard over....fact) and in no case was either servo ganged with another!!!

Search: " 8411 failures"......85 threads with many featuring Hitec failures, almost not about a JR! The point is no matter what brand you look up it always comes back to Hitec with the highest failure rate! Never did we hear about this rate of failures until Hitecs became widely available! Guys have been ganging servos for years....and without match boxes! Did we hear about this kind of failure rate...no! There was a poll that followed the above post that jonkoppisch mentioned that had 16 out of 85 Hitec users checking the "had a failure" box! That is rediculas!!

If you have had great luck...more power to ya! I sincerely hope you get another 1000 flights! But when someone says that they failed and yours didn't consider yourself lucky that it wasn't your $4000-$8000 investment that was destroyed cause of a Hitec servo. Find one guy that lost a plane due to a JR ot Futaba servo failure and I will put up cash that I can find at least 5 that lost one due to Hitec! This is based on all the information available to us...............not just my one bad experience. If you want to bury you head in the sand..go ahead it's your money. If you want to drink the Cool-Aid well.....bottoms up! After all my plane had eight 5945s in it and ONLY TWO failed! Hey that's not bad odds....right?

Leardrive

Hey, I didn't mention that!!! I was involved in the thread but didn't mention the post. More misinformation!!!!!

Here's what leardriver posted though

Quote from leardriver

"Oh yes I did loose my first 2.6 Extra when the motor quit (another story) but what Marc didn't tell you is that on the 5th or 6th flight of the the replacement the rudder servos (Hitec 5945s) went hard over 30 degrees and locked solid"

So it was the second airframe (wrecked first one) that the servos were used on. Hmmm!!!

Then there's

Quote from leardriver

"I started to second guess myself why these "brand new (9-10 flights) servos would fail as such. I put in about 2% right rudder to throttle mix at 1/2 stick and above in an effort to "fine tune" the up lines. After the servos locked out I started to second guess whether or not I had "linked" the two servos in the TX or not.....as it turns out I did! What I did observe when installing the new servos was a tiny little bit of lead/lag between the two servos because I used a pmix and had one servo in ch4 and the other in ch8 (I think).."

another Hmmmmm!!!!!

But I'm sure it was just the hitec servos you know

+ if you look at this thread where he asked for opinions I see a lot, probably close to 100 right here so far with only your failure of 1.

Hmmmm!!!!!!

Where's that 16 out of 85?

Hmmmmm!!!!!!

Here's a pic of my glitching hitec servos at work in my 40% comp arf extra

(I know they're glitching cause there's no way I can do this, lol)

YOu need a thread...hang on....coming right up!

http://www.rcuniverse.com/forum/m_22...tm.htm#2268245

And I have PM you privately and clarified all of the quotes you are posting...many of which are not suprisingly twisted in the meaning, but you can take the failures that I had out of the equations and you still come up with servos with a MUCH higher failure rate than a JR or Futaba. You can debate it till the cows come home but the threads are all there.

HMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM........what an *****


Leardriver

They're not twisted. I listed the postings so that everyone could check it out themselves. Talk about an *****

PS,
Yes you pm'd me then started ranting and cussing like a lunatic... and I quote from the PM
