8717

Man do they looked cool!!!! The only thing you missed on was the G7703D gyro with the DS8900Z servo which also has the red heat sink. Also cheaper that the 611 and according to many pilots it also has a great holding power, and in some cases better than the 611.

Well I`ve got the G770 on board but my 8900 is tucked away between the frames - only 8231`s on the cyclics so no more red I`m afraid

Isnt that one of the prototypes?? I personally went with the 611, cause I couldn't wait any longer... it kept getting backordered and when it said Aug 30, I gave up an bought the 611 so I could fly...

But Honey, I can't live with just stock.....

No, I think that the G770 is just labled up a bit differently in the UK to the US - same as the G500 and the G490T .

I am very happy with the 611, just hated to spend another $100 to get the good results

But Honey, I can't live with just stock.....

I've been using these 8717s & 8915s for a while now and they are just the best thing, makes the head ultra responsive....wouldn't use anyting else at the moment. Inly need to shave a mm or so off the 600n frames, but fitted my scedau perfectly.

Where did you get your 8717s from? I haven't found anyone in the UK who has them in stock?

Hi Guys

I just ordered 3 by heliproz last sunday, but now they either have them in stock.
I know that this will not help you out, but maybe ask them when they will have them in again.
Hopefully mine will come next week. Then we will see how bad these suckers are
Anyway,are these the samme as Allan Szabo use? I k now hes are Spektrum but they could be the same or am I wrong?
Regards Janis

They are what Szabo uses, except he runs them at like 8 volts, or something, to be able to do the new wiggle maneuvers. I know they were on the machine he used to win XFC

My friend uses the 8711's in his Synergy...killer servo's.

The unmatched power of JR’s DS8711 standard-size digital servo is nothing short of astonishing. But the 8711’s story doesn’t end with its awesome power. The 8711 also has all the speed, the holding-power and the zero-deadband precision.

Specs

Type: Digital Ultra Torque
Torque: 347 oz/in @ 4.8V, 403 oz/in @ 6V
Speed: .19 sec/60° @ 4.8V, .15 sec/60° @ 6V
Dimensions (WxLxH): .82" x 1.58" x 1.56"
Weight: 2.36 oz
Gears: Metal alloy

I'm not sure they are stock 8717's those boys are running straight off 2s. The spektrum guys have been swapping motors and gears like crazy. I know Daniel mentioned it as well, but also wasn't sure if the motor was stock.

I'd love to see some real confirmation that we can take an unmodified 8717 off the shelf and slam them with 8.4V on a fresh 2s lipo. Surely JR would be bragging about it if it was in the design spec? We know the 8v prototypes have been around for a while.

These or an 8v version are definately going in my next bird. Heh or sooner if they show up on a LHS shelf.

Hi Guys,

Ok, 8,4 V thats sounds awesome. But i think that JR would have written it on their specs for the Servo 8717? I think I only will use 5,9 V.It would be a pitty to burn the servo because of wrong voltage.Maybe the guys which are sponsored could try it out for us the will get some new for free anywau, ha ha ha ha

These have to be the best servos I have ever owned. They ROCK. Not much else to say.. And I thought my Raptor 50 with Fut 9451's flew great. The control, power and speed of these servos is outstanding! My 600N is awesome in the air with these babies installed.

Well worth the money and will definitely be using them in my Aurora if they still make them in the next century when it's finally released. LOL!!!

How are the servos holding up? Any slope developing in the metal gears over time? How many flights would you say you have on yours now?
Thanks for any info in regards to these servos.

Ive been slamming hard on them and creashed​once.

adn the servos are holding up perfectly. I brought it in hard while inverted and tried to roll out on an engine failure and hit hard. My first worry were the servos but nothing happened to them.

8717Servo's

After some aprehension, I installed them along with the JR 770T gyro in my Trex 600N. I can only tell you that they are the only servo's that I will use again. The manufacturers are catching on as the RJX Extreme 50 have made allowances for them also the new JR Vibe 50.

The gyro is more than equal to the 611 as far as I am concerned. Finally JR made a good unit. The piro rate is bolistic and holds firm.

I don't regret filing the Trex 600N frames a little to make them fit.

This is a winning combination for sure.

CJ,

I've had these servos for several months now and wouldn't change them for anything.

I must have put 30+ gallons through the machine and there is no issue with the servos what so ever, and I tend to have a hard smash every month which requires new landing gear, blades spindles boom or some other part.

One of my machines still has a Futaba 9kg digital servo on the pitch and it just doesn't come close to the performance of these JR ones.

Best investment I ever made, makes everything crisp and smooth......
