8711 or 5955

No Wayne, I do not use either one, but I do know what is the best. I won't buy something without reading about it for at least a month, researching and calling the companies up. 5955TG's all the way.

5955's all the way...Ive never had 8711's..10 8611's with crappy gears were enough for me..

Because... if it is printed on the Internet... it must be true!

Well I have owned 8511's and can honestly say they develop gear play very quickly l(ike in 20 flights). From what I have read the 8711's do not have a revised gear train over the 8511's which immediately hands my vote to the Hitec's.

Though having said that I did recently change out a 5955 from the elevator in my super extra after 55 flights. It had not developed slop, but when unpowered I noticed it had a spot where it would 'stop' when the surface was rotated gently by handm like something was causing it to 'lock'. I have yet to pull the servo apart to look for the cause.

The servo operates perfectly normally while powered but I decieded to play it safe and swap it.
So the moral to that little story is that no matter how bullet proof you have read your brand of servo is you should always be inspecting and looking for any signs of wear or abnormal operation.

No, this was with no power neo. It was simply that the servo had a spot in the gears where it would 'self lock'. It is only evident when unpowered as the servo motor would always pull it past the locking spot.


Note, its not like a full lock up, more like a bit of crap in the gears, like I said I havnt pulled it apart to check yet.

Sorry, but then it's not really fair to tell someone what to buy is it?

I've been using 8611's for a few years now and yes they develop slop but to me the airplanes always still feel completely locked in and precise.

Never used the Hitecs or the 8711 so I can't comment on what to use. But since I have had great luck with the JR's I'll probably try them the next time I need to buy servos.

I tried 5955's on my latest 35%. The 2 elevator servos had a noticeable "racheting". I talked to Hitec on the phone and they could even hear this stepping over the phone. The linkages were good with no slop, proper mechanical advantage etc. I substituted 8611a's for the elevators and the racheting or stepping went away. I've been running 8611 and 8611a servos for 3 years now and although I can feel some slop, it's not enough yet to send in any servos.

Be careful what you read. Some people who talk about all this slop on 8611's have never actually used them. Not saying the 5955's are bad, but I prefer the 8611's. Can't comment specifically on the 8711's but I'm sure they are similar to the 8611a's.

[notorious_benny]

Yes the hitec's have a little bit of stepping that is more noticeable if moved slowly. I agree that this is their biggest negative.

I have found it is not noticeable in flight, and depending on what type of flying you are into it can be practically eliminated by running short servo arms to give the linkage the best mechanical advantage and the surface the best resolution for IMAC style flying.
Even for 3D that little bit of stepping shouldnt bother you. I have 3D rates on my super xtra with 5955's and cant feel the stepping when flying IMAC.

I have used both types of servo's. The 8511 seems to offer better resolution when you play with it on the bench, however, as I said above, I cannot detect a difference in feel whilst inflight, and so prefer the tight gear train of the 5955.

my apologies....I mis read your post of unpowered as underpowered. I deleted my previous post as to not confuse others.

I really think that the JR's are a nice servo that will last a long time with Horizon ... they are good at backing them. Hitec's, never had one go bad, so I don't know about customer service. I think it is a matter of which you like better, which is a better deal to you. Do you already have the servo arms and so forth for JR? Or Hitec? Things like that. The ONLY reason I did not suggest JR is the slop. That just bugs me. Might as well run 2-56 bolts in 4-40 holes too....

I have been flying JR 8425 / 8411 for 4months now.
I was very pleased with the servo's in the beginning but now...
after only 4months
The gears are totally wasted.
And around center they are shaking for +/- 4mm ...(if you don't believe me I'll make a video )
That for servo's of over 110$???
I can tell you 1 thing!
If graupner/Jr does nothing to help me solve this problem I will never buy one single JR again!!!

About the hitec's it seems the specs of the hitec's are very good but as said before, most people say the number of steps is not very much... so for imac flying ????

Right now, the 5955s are the only way to go. As far as the 8711s, they are kinda like the 2.4 gHz stuff. I am going to sit back and see how things pan out.

Not once have I heard a problem from the 5955's, and have 28 of them with no problems.

I love my 5955's, soon I will upgrade all my servos to these. They are fast, smooth, and the titanium gears don't really show wear.
