7HV and 9180 servo with compass arms @ 17.5mm work with vbar ( see last post))

[AnTi Taco]

for the guys using the outrage servos what servo arms did u end up using...i was gunna use the stock outrage wheels like i always do when i use outrage servos but this helis is direct to swash and don't think it would look right with circle wheel so wanna see what others are using and what i should use..i do wanna stay away from metal servo arms cause i hear the strip your gears in a crash and i rather strip a plastic arm instead...

Yeah I was just measuring this up when installing my servos and noticed none of the Outrage options really gave me the 17.5 thats called for.

Stock Atom 500 futaba arms work perfect on Outrage, MKS ot Futaba servos. Give you exactly 17.5mm from center

Thanks for the heads up, just placed an order for some.

Hyperion, Savox and Align too.

I used the stock compass arms from the 6hv

[John Cook]

yeah the atom 500/6hv Futaba arms. Or you can use the MKS 4 point heavy duty arm, and cut all arms off but one.

Any Futaba splined arm will work, it's just getting it long enough and then strong enough that's the trick.

I just started building my 7HV and I have Outrage 9180's for the cyclic servos. I went by the hobby shop today and picked up the Du-Bro Super Strength arms and they did not work out. The nut on the ball link hit the metal bearing block because the Du-Bro arms stick out very far from the servo. I guess I will have to wait and order some different arms.

The arms that come with the Outrage servos are strong enough, but the best hole is at 19.5mm. Will that 2mm make a huge difference?

i didnt open every bag in my 7hv kit but does the kit come with any servo arms like the 6hv did?

Mine did not.

[AnTi Taco]

I.use the atom.500.stock.servo.arms.that come.with the 6hv on both my 6hv's and I would.like to use them.also.on.my 7hv but I'm a little worried that they won't home up....they don't seem like there that strong....would u guys trust them on your 7hv?

[Gawl]

Got the Atom 500 arms in the mail today, I don't see how these fit the Outrage servos. The splines line up but trying to push the arm on...forget about it.

[heathy]

Mine were tight, but went on fine. You are using the futaba ones??

[Gawl]

Yeah, its going on but I'm having to REALLY push it. Very very tight fit.

yeah i use them on my 6hv with those arms and they are a tight fit but i guess that a good thing

[John Cook]

Dave Kettlehut, and I use the atom arms. I think Eric Brandenburg uses them too. Tony uses the MKS arms that he trims as I mentioned in my prior post.

The compass arm hold up fine in flight, at least that's my experience. In crashes they are prone to stripping the splines though, so keep some spares around. I think the MKS arms are beefier, so probably less likely to strip, but you are just moving a point of damage somewhere else IMO, ie other links etc... Something has to give you know!

The compass futaba arms are sold out everywhere any one have a link to the DuBro arms that work? these the ones right?? if so i have a set of these already that i got in a trade but they are the JR ones (WHITE ones) and from the center of the screw to last hole is 18.5mm so its 1mm over the suggested 17.5 mm is that ok?? also are the stock atom 500 futaba ones 17.5 exactly? i know a post

I tried these with the Outrage servos and found they stuck out too far on the elevator servo. The nut would hit on the metal bearing block.
