will it still wag...

[sly the dogman]

Been silent lately, chasing a wag, a real bummer. Servo froze upon landing last week, no damage though. Should receive new servo tomorow or friday. I'm converting to 5.5. I just hope that the heli will be wag-free other wise I'll be very sad. (sad is an understatment). I tried and or changed every thing else that I could possibly think of, hope this is the cure.

to be continued.....

Received the servo today, as faith would have it, didn't order the right one (da !).
I ordered a DH16 High Voltage instead of the DS16.
If I order & install the High Voltage servos all around, do I need something special on the heli since its high voltage !!! What does that do compared to the non-high voltage servos. I know the specs are different but besides that.
I have the stretch version with a CC 75A or a HW 80A, can also install a BEC, if needed.

Never order heli stuff when sedated, even mildly, DH16 & DS16 look strangely the same when ordering on medication. lol

I assume that's the DH16-GCD? You should have no issues with running that servo at 6V. Based on the specs I found, the difference is 0.01 seconds between 6 and 7.4V, which is pretty negligible.

Well, its actually DH16 FMD

Wich is the best for cyclick ;
DS20 GCD : 9.0 @ 7.4V / 0.06
DS20 SMD : 16.0 @ 6.0V / 0.15

100% agree with Bum on this one. Chances are even a top-end flier wouldn't really notice the .01 second difference either, so you should be good to go.

As to eventually going all HV, it doesn't make much sense (yet) on a 500 class because most BEC's and servos are still rated at only 6V. Unless you're willing to dump a good sum of money to say you've got HV's, I don't really think it's worth worrying about. Until they introduce brushless mini servos anyway.

I don't fully "understand", what you just said here Tim, sorry.

a) it doesn't make much sense.........at only 6V. Why doesn't it make sense ?

b) I'm not dumping a good some of money, they're the same price as a non HV servo.

c) What ? isn't it worth worrying about

Is it a good thing to have HV servos or not ?
If so I'll buy 2 more, if not I'll ask Jeff to take it back and get some DS20's, that's all

[sly the dogman]

If I run HV servos on cyclick at 6V, what about the tail servo, a JR8900 ?
Will I need a step down ?

Hey Sly,
The DS 20's won't fit a 500 for cyclic but a 20GCD Hv or not will fit for the tail.
I have the DH 16FMD's (Hv) on mine for cyclic running at 6V they are pretty good.
For the tail I am running the DH 20GCD (Hv) also at 6V and it does a good job.

If you wish to upgrade your swash servo's(not going to help your tail wag)
to Hv's to run at 6V you will need a step down for your JR8900.

I would just send the 16 back to Jeff and swap it for the 20GCD.

All this assuming your tail servo was the one that locked up?

Hi all, I have the messy slow tail wag in hover too... Im using Savox 1290MG full size, carbon pushrod, all movement soft as silk. I still have tail wag at hover.. running 3GX v2.0 unit, wag almost dissapeared, but still a little present. I will continue playing with tail lock gain to see if it disappears. Fly is perfect, only have slow tail wag in hover. Also upgraded my CC Ice 75 to 4.01 firmware and no noticeable changes detected.

I beleive its the elevater servo that froze up (stated in earlier post, somewhere).
I was just a bit worried about the 8900 on 6V, some say don't need a step down, some do, some even with a step down the servo burned, step down nothing but a peice of wire, gotta use 2s life pack on the Rx. Very, very confusing, to much info is as bad as not enough, you know. I pmed Alan, 1 voice, 1 response and that's that.
I just ordered 2 more HV servos from Jeff's lovely shipping manager.
And for sure it won't stop the wag, but at least I won't crash making tests. This heli will be completely re-built from tail-end to frame, servos, main shaft, spindle, some parts on the head, fly-bar, blades. Now if it wags, I dare not think about it.....

Sly,

"If I run HV servos on cyclick at 6V, what about the tail servo, a JR8900 ?"

You definitely need a step down for the 8900G, my friend!

Got one !

Can I still run 5V with HV servos or I HAVE to run 6V

You can run HV servos at 5V. They'll just be a bit slower.

[sly the dogman]

You told me that yesterday Alan.....didn't mean to be doudtfull.

[sly the dogman]

And to answer my question : no it doesn't wag or drift.......fiou !
