5065mg issues!!!

[sjsamuel]

Alright...so I crashed my pro for the first time the other day..pretty descent spill..inverted pass and just dumb thumed it..
Broke the regular stuff - main shaft, head retaining bold broke and the head came apart but supprisingly everything was goon on the head including feather shaft. Broke a couple of links and bent the boom and stripped some gears...
Now the first thing I notice after unplugging is that I've got some gritty feel to aeil/pitch servos(stripped, I assume) But the elevator servo seems to move fine...
Today, I finally got the servo gear sets in and I rebuilt the front two servos which were in fact stripped..I plug one into the receiver and it gets hot..and its toast..I get nervous that its my esc so I plug a cheapo servo sitting around and its fine..So I tried the second rebuilt servo..and BAM its toast!!...Now I'm really frustrated
I happened to have another 5065mg sitting around that stripped from another crash on my v2 so I rebuilt it with new gears and say a quick prayer and plug it in and it works..I'm excited again since I have one new 5065 still in the box this rebuilt one and my elevator servo still in the bird..which I assume was good - I'll be flying in no time I thought!! Well..I plug all three in to center and such..and I get nothing from the elevator servo..I quickly unplug..remove it and although there is no binding or anything from this guy...its smoked as well!! Once again... Talk about an emotional roller coaster!!
Anyway, WHAT"S THE DEAL HERE!! I fried all three servos in one crash...even though only two were stripped..
I crashed with 5065mg's before and even harder I might add with my se V2 and have not done this...Are the placement of the servos in the pro making them more vulnerable..This has turned into a very very expensive crash...Please I beg you help me understand this..I'm gonna be very afraid to fly this thing if its gonna be this expensive everytime I go down!!!
Sorry for being wordy again..I can't help it..and thanks guys ahead of time!!

Think about this... If you crash, and two of the three servos are striped and locked in an abnormal position, enough to burn the motor/ board out. What are the chances that they aren't pulling the third into an un-commanded position, causing the motor/board to burn out?

I have had bad luck with the HS5065s myself... they are a wonderful servo, fast center well and good torque, but they are pron to burn out!

Buy the Hitec servo programmer and set OLP to 20%. It will save your motors next time you strip your gears.

[sjsamuel]

I've never heard of this programer. How dies it work? Where can I get one??

After I posted I found the 5065mg problems thread..does hitech still repair these things? Snjbird I saw you had sent some back to them in the past...?

I have the same problem with the 5065's. The HS-65MG's were BULLET PROOF.
I have gone through SIX 5065's in two crashes.
I jut switched to Spectrum H-3000's, will see if they are any better...

Wow..I can't afford to fly at this cost..I'm still learning and crashing is still more frequent than I would like. But its gonna happen again..

[Mystic3D]

The only and I repeat the only reason I run digital 5065's and H-3000's is for flybarless.
HS-65MG's is a much better way to go, at least 10 crashes on mine and 40 crashes on my buddies three 450's and not 1, servo failure.

There Is a 3year waranty on the 5065 just send them back to horizon and they will repair it. Here are the three programmers hitecrcd sells they are all in stock at horizon

Back to Hitec, did that with 3 of them.
They replaced 1, and sent back the other 2 burned up ones , saying gear stripped, no warranty. The recepit I sent in was 2 weeks after I purchased them...

[sjsamuel]

My head is spinning guys!! I don't know what to do.
1. I could purchase another set of 5065's and the programmer as suggested. But is this gonna solve this the issue? What's the opinion?
I'm still hoping hitec will warranty atleast one of those servos.
2. I'm not using FBL so should I just get rid of the digitals and go to the 65mg's. My local club guys swear I need digitals. So I'm lost there as well

[sjsamuel]

Alright folks..just did a whole bunch of reading including manual for hpp-21.
In theory this seems like it would be a benefit if one would want to use digital cyclic like the 5065, one could turn on olp(overload protection- for those like me who did not know what that meant) and potentially save a servo in a binding situation..like a crash. This feature turns down the amount of power sent to the servo motor in such binding situations, by a set percentage(20% recommended above). Less heat is therefore created..= less chance of damage.

My question is are there any of you seeing a real world benefit with this.
Once again trying to justify staying with my 5065's which I really like but can't afford if they're gonna burn with all my crashes.

[Mystic3D]

On a Flybar 450 you cannot tell the difference between HS-65's and HS5065's. I ran HS-65's for 2 years before I switched to flybarless and 5065's. I have had more problems(each time I crash) with servos, I have considered going back to flybar and HS-65MG's.

Simply not worth the trouble. The 450 is my try new things on bird as repair costs are low. If I were in your shoes I would sell the 5065's and go get some 65MG's.
No point in dumpiing more money when there is no difference in flight performance.

Man I definitely hear what you saying...that's what I wanted to know..
I'm starting to do some 3d and it seems like 65mg will be just fine in my pro. 5065 sound good cause they are digital but I need to get over that stigma

[Mystic3D]

I know exactly how you feel. You feel like you are going backwards. But in this case going backwards is a benefit. I absolutely hate the fact I have wasted about $200 on servos(5065) in two crashes.

[sjsamuel]

Yeah..I'm still hoping against odds that hitch will replace/fix atleast one of the three..I've got two brand new 5065. And then I can sell a set of 3 to someone else wanting to take up the challenge..and that will help differ the cost of the "downgrade!"
Any ideas where I can get a set of 65mg for a good price?

[sjsamuel]

Well guys...went by the heli field today..although I had not bird to fly ..but I got to talking to some of the guys there that have been doing this for ages..and one of them is suggesting I go for the JR 285mg's. Now I know is more money...but he flies them in his rave 450 and has crashed with good survivability. He reports that there is a small karbonite gear that gives sometimes but he does not recall ever burning a servo!!
What do guys think about these things??
I'll be spending about 30 dollars more from heliproz.com for these compared to the 65mg's and was curious about opinions on here?

[Mystic3D]

Between my 2 450's and my buddies 3 450's over 2 years over 1000 total flights with 65's not 1 problem.

No experience with 285mg's.

[sjsamuel]

Well once again after much contemplation 65mg has won. Especially since I picked up a near new set from a friend wanting to get rid of them. I'll be flying them tuesday...and will try and get back with my final results...till then thanks for the info everyone..

[Mystic3D]

Crash them 10 times then judge....
Seriously hope you don't crash..

That's not funny -- I'll be back in a week with the 10 crash report...just kidding..
