I spoke too soon

[steelie600]

Today i have receved from Fast-Lads an align gp700 gyro and servo,and im quite looking forward to usig it as i keep hearing good things. Parcel was delivered to work so i can hide cost LOL. so here i am back at home with new gyro and servo fitted to k3d. Going through the setup phase, servo direction......fine, gyro setup, bandwidth......fine, ds/as........ fine, gyro sensing............fine,............ hang on whys the servo stopped????

Basically within 2 mins the bleedin servos died goes hard over to the left if your lookin at the horn and thats where it stays........ Hang on lemme just try the servo onits own nope still doing it. Lets try it in another system to see if its a radio fault............STILL THE EFFING SAME!! BASTID!! I was singing align electronics praises earlier and theyve let me down!!!.

I have tried a 9254 in the gyro and all seems to be fine but i dont particularly want a 9254 in there.

I now i should be ringing Jamie and the boys first but at 12:30 i bet theyre all tucked up in bed. But here it is another documented faliure of an align servo!!

let this be a warning!!!! dunno if i trust this servo to be a tail servo so what i may do is buy a real tail servo and have this one as me throttle. hmmm

[Dashik]

Well to be fair how many servos have they sold v how many are actually faulty? Its like anything you buy. Theres always going to be the odd DOA.

It is however a real PIA when it happens to you!

My 4 Align servos are all working fine so far........

[steelie600]

Hmm im with you there, ive got align cyclics inbothmy helis and they seem to be fine and as you say it could just be a one off, but the probs ive heard about have only been with the 620 not the 610, so i bit scared really as i cant afford another crash for atleast 2 months

[moyesboy]

Where do you read about the "documented failures"
On the "dark side"?
Sometimes I think that place is full of trolls from rival manufacturers posting made up problems with new rival kit.

As far as I know you have the first documented failure reported here.
Infant fatality is a lot better than a long term reliability problem!

[steelie600]

yup twas on the dark side lol. tbh i only go on bumryder to entertain meself with how dumb the sherman tanks are but all the failures on ther have been with the 620. Im gonna ring fastlads in 2 secs and after ive slept on it now im gonna give the servo a pop anyway cos its only gonna be a one off isnt it. I think now ive sobered up and had a kip the message in the thread should be give the servo a thourogh testing before flight.

[Smoothound]

People persist in using 9254's and yet they also have a high failure rate so i'd not be too concerned yet. If the new one does the same either get something else or buy a lottery ticket

[jiberjaber]

I dont want to tempt fait but not had a problem with my 9254 as yet. I have one on the throttle and on the tail.

[steelie600]

must admit ive never been able to fault a 9254, ive seen one thats rouh in transition but it holds well on the gyro

[moyesboy]

I think now ive sobered up and had a kip the message in the thread should be give the servo a thourogh testing before flight.

You haven't got the hang of this have you. Now you found a faulty serevo before you even flew, you are supposed to say how its crashed your $1500 heli and might have killed you, then bang on and on about it and how you are not going to settle for less than a complete set of spares for you "repairs".
Then invent yourself another 5 identities who all post saying they had the same problem.
Then get banned becuase the supplier is an advertiser.
...oh wait a minute, I'm in the wrong forum.

Hmmmm, funny that i'm trying to ween myself off!!!!

[cambs flyer]

Sorry to hear that Kev' its all a bit worrying as I take what you guys say as gospel, but my S9257 so far on my 500 has been as good as gold, and talk about fast.

Then again my 500 has an easy life compared to flying you chaps perform.

I've had a few 9254 servos fail over a few years of usage - all used as tail servos.
I'm about to give the 620 a shot as a tail servo as the 610s are working very well for me.
My only concern with them is the servo cases being potentially a bit brittle - having used three 610s for cyclics on my Trex700 for about 20 or so flights, and no crashes etc - two of the three had a broken mounting lug (snapped off at the side of the servo case).

Replacement cases are under £3 (for tops and bottoms) and take all of 2 minutes to replace, but thats hardly the point

Cheers,

On t'other forum the 620's as tail servos don't seem to be too popular, comments around being a little slow so interested to see how you get on with it.

I've also had issues with 9254's used on the tail, lost around 2 in three years that randomly let go. There's a very long thread on RR about failures.

I'm very happy with the 8900g, although there are a few that have had problems with these. My BLS251 has been very good too in partnership with a Spartan gyro.

[robgt]

The 620 spec is very good. 0.07 @ 60 degrees (the 9254 is 0.06) but the 620 can handle 10 kilos/cm of torque almost 3 times that of the 9254 (which does around 3.3 k/cm)!

I can't see how someone would notice a speed difference of 1/100th of a second, but it remains to be seen, I guess
Cheers,
Rob

[Smoothound]

To be honest, the additional torque should make up for the speed deficit surely if you are working the rail hard?

Having a fast servo means beggar all unless it has some torque to back it up!
