I think Mikes just trying to show they have found a solution,been a loooooooong go of it,but a solution better than none.

Tavis just has to get his radio back from the service center, and get 50 flights on them so that he can give his take on things.

OK. So do I need to send in all my 7950's for an upgrade of some sort?

I don't know if they ever will be either.
They are showing promise, but they need some flights on them to see what happens.
Then a lot of flights to prove to me that I can go back to Hitec, the brand of servos that I once loved.
So all of that info in post 4345 is of the servos in an airplane, in a garage.
No actual flying.

Exactly!

Edit: And Tavis said the issues with is TX are RECENT. Remember he bought a A9 just to debunk the TX theory.

So has anybody been using these servos successfully?

I saw a video on youtube where a guy showed a jitter problem, but he has his comments moderated for some reason.

Whenever I see something crazy like that I think there has to be something wrong with the power distribution, or PWM signal, or something else.

I use a lot of 5245s, 7245s, 5065s, and 5085 servos from hitec, and like them.

I am debating the JR servos or the 7250TH servos, and am trying to figure out how much of a problem this really is.

I'm sure someone must have had some success with them but I've had nothing but problems. If you want to know the kind of problems people where having, there is 290 pages of information in this thread and it's all been said before.

The thing that bothered me most was that Hitecs support of the people that where having problems with them for a very long time was pitiful at best. Also, they aren't even significantly less expensive than the JRs. Based on any thing that is important to me, (performance, service and price) I simply see no reason to buy hitec servos ever again.

I have several of the 7950 and 7955's. I'm getting a bit of jitter on the two 50's that are controlling my rudder on a 37% Edge, after 160 flights or so. The others seem to be holding up ok. I too read the thread here on Giants, and based mostly on that, and to a lessor extent on my jitter problems with my rudder servos, I'll be switching to Savox.

Same here. I have about 130 flights on mine. The gear train is not at tight as when brand new. Seemed to loosen up with the first few flights but seem to be about the same and have not changed much. No more gear lash than Futaba and Savox gear trains that i have felt.

I got three font have any jittering problems but have seen some centering problems in a buddies plane seem like every flight the elevators loose there trim and need re trimes

If he is losing trim then more than likely he needs a new pot fitted.

We have done a lot of work on solving the jitter issues and other problems there will be an updated servo soon i think I don't know what HITEC is going to do . I don't know what HITECRCD is going to do about all those servos out there either.

I didn't post the repairs that could be done by the owner due to lack of desire by owners to fix them.
If you read the ending posts you will see that every one was going to Savox .I personally like HITEC servos especially the programmable center and end points.

Rachael:
I have followed this thread from the beginning. Your statement above baffles me. If someone were to read your past posts, they would clearly discover that you did not post the entire fix because you were trying to recoupe your monetary efforts from Hitec/HitecRCD. Your current statement is not a fair one on many levels. If I buy a 65" LCD TV and it fails to work as advertised, I can either chock up the cost to lesson's learned and move on, or I can take on the manufacturer and demand they fix my issue. The problem is convoluted when it involves a company outside of the USA because they do not have to play by the same rules without an actual trade agreement. Fat chance getting them to pay for or fix the situation even with a trade agreement on your side. Who is going to travel outside the USA to take on Hitec for a crappy servo? The costs would be daunting.

Now, how many people would opt to fix their own TV just because a well meaning person proposes the perfect fix? Do you know how many people do not even know how to use simple hand tools, even in this hobby? You would be amazed...

So, you owe it to all those who do not wish to go back and read through hundreds of posts in this thread to set the record straight. You did not post the entire fix because you wanted Hitec to cut a deal with you, and not just use your fix to repair all of the errant servos without compensating you in the process. I agree your fix is the correct way to get the servos up and operational BUT I still would not fix my own TV with your instructions...

Another part of the problem is that your list of discrete components were not all available here in the USA, so we were still stuck, trying to cross reference the components listed to those that were actually available. In other words, find an alternative component to the ones listed. Most folks were not successful in that endeavor. Capacitors were one of the components not available, along with the correct rated pot (that I remember).

Another point of confusion that held up the "fix" process was when you disappeared from the thread for significant chunks of time. We later found out (with the help of Denise posting under your name and also under her own account...very confusing at the time) that you were battling a serious illness. The "fix" was put on-hold (and rightfully so) until you recovered completely. Is any of the aforementioned begining to sound familar????

Now, I am aware that you were willing to give the the entire long term fix to those that would send you a PM, etc...I have no way of knowing if anyone took you up on your gracious offer.

Respectfully,
Smacka

Rachael you want programming? futaba s9075sb 30.5kg 0.14sec@6v for the same price as the 7950 it's fully programable and can be used with any radio not just sbus. they are 6v thiugh not 7.4 and are also only $10 more than the 7955.

Is this a common problem people are experiencing with the 7950? Brand new out the box today

Yup, just wait until you get it hooked up. Then it will start shaking and will not stop.
