I was wondering if this model uses the same traditional Synergy arms? The carbon tear drop shape piece that bolts to a plastic wheel? Just getting stuff together.... Thanks
-
No it does not. You will just use the servo horns that is supplyed with your servos.
-
OK thank you, glad I asked.
-
As always if you are using metal gear servos then use plastic servo arms. That will save some heartache :)
-
Futaba style spline, we're recommending 14-16mm. The mks servos came with 17mm and the geometry was a bit aggressive.

So what brand/type did you end up using to get 15mm? cyclic arms for the prototypes?

Hitec has a futaba spline 15mm.

So being a fairly inexperienced builder, where would I order these arms? Just to be clear, I DON"T want to use the arms that come with the MKS? 8)

The dubros are 16mm and sab 500 arms are 15mm. We've been flying some different configurations lately and updated the manual to recommend 15-17mm arms. Off the record, 15 works well with vbar/ikon numbers and 17 works well with cgy.

The Mikado servo arms also work well... if I recall they were 17mm using the center hole.
-
Again, could someone recommend specifically what/where to order for the servo arms?
THANKS!!

I'd start with the ones that came with the servos. If none of those are suitable, then look at some of the other options mentioned. On larger helis, I like the Dubro heavy duty arms, but on this 516 with mini servos, I'd probably go with regular Dubros.

I'm Using the Futaba aluminum 20mm single arms. The second hole is 16mm distance so I just drilled it and tapped 3mm then red locktited the balls in. Using futaba 173 servos . cgy750 settings in the 50's for both cyclic and pitch, so they're perfect. Provides for 15/15 collective and 10/10 cyclic

Thats straight from Mikado USA... Amain carries them as well, but currently out of stock there.. A quick google search will provide u several other vendors as well.

i was going to order the mks 9767 servos but this arm discussion is confusing me.
the arms that come with the servos are not suitable for the the 516? we should be ordering other arms to use?

As long as the arms provide 15-16mm ball spacing, they should work.

I use the MKS horns with 17mm on my 516. Cyclic throw is perfect on my Vortex. And it flies awesome too.

I would deal with Allen , I have gotten great service from him. Got a problem he helps you out. Prices are in line with the other big Dogs!

I ended up using SAB arms at 15mm flys great

Be advised that the Dubro super strength arms may result in stripped servo gears in a crash. They’re that tough and rigid. They also have more clearance from the servo case, which might throw your geometry off. I’d advise the regular arms if you’re going Dubro.

Please, provide a part description or weblink for these Futaba arms with 16mm holes.

Why is this? Is it for crash safety or some sort of RFI thing?
Thanks.
