I would hope they are included as we have no clue as to what spline they are or length needed. This is new territory unless I missed something. I've got batteries, mini Brain2, and Jeti rx all ready for it. Sure would suck to have to delay the build for appropriate servo arms

Parts are now listed on SAB's site, as well as the servo horns.

The integrated motor is certainly interesting from a design pov, although I've had zero hassle with the simple gear drive on the OXY. So is it really a step forward? Well as a designer myself, reducing parts count is always a good aim, but only if there are no other compromises. So let's see how this SAB motor and new airframe actually perform when they start shipping.

Parts costs will also be key on a heli like this, as OXY parts are pretty reasonably priced. SAB parts are usually expensive, plastic or not. I was surprised how much it cost to get my G380 back on its feet after damaging a side frame, lower plastic tray and skids.
+1 on all you said. I love my Oxys and they fly incredibly well on 4S. If this is offered in a 4S setup one day I would consider one, but with the weight of this thing, it looks like you need 6S for it to be at a good performance level. I don't like the lack of flexibility as with the Oxy and 3S-6S. But, if I was already running a 6S Oxy I would have already ordered if I could share the packs. IMO, it is definitely the ugly-duckling of the SAB helis and sort of looks cheap. Not because of the plastic either compared to other SAB helis. The Comet still retains some good looks. But, looks aren't everything.

Me too.
Parts aren't as bad as I thought they would be on first glance.

In going to the SAB website I saw that the a servo comes with a servo horn, so I'm going to assume each one in the kit will as well. Had to buy a bag for it though. Damn, got all I need to start but the Heli.

Now I see its delayed again till the end of July, patience trainig

What I see is "...around 2 week delay" posted on June 29th on their website, which puts the estimated date of July 12th for arrival to dealers. Hopefully I'm not missing anything either......

Ah- yeah that's the new date alright...I thought you meant another 2 weeks from there!
SAB USA has stated the 12th for a few days now- so hopefully that's firm.

No need to apologize, I think I'll speak for myself in saying that I'm a little excited to get this new toy:-)

Yeah, would be nice to be able to share packs with the OXY 3. I'm currently running my OXY 3 on 3S packs, but I'd consider converting it to 6S if it could then share packs with the SAB. But not sure I'd actually keep both these little helis long term. I'll probably try the SAB next season when there is a decent amount of user feedback (assuming positive) and probably a stretch option. Then I'll run them back-to-back for a while and then continue longer term with the one I like best. I love this size of heli for its convenience, but only need one in my fleet. OXY 3 has been almost faultless, but I do like to try new things.

Since the 60a v4 weighs the same as the 50 but has telemetry capability people end up going with it. Total overkill amp wise but a lot more features for a small weight penalty over the 40a. Tareq uses a 40a on the Oxy with the Xnova motor so no one on the planet really needs more than a 40a other than wanting more features.

I would guess the same goes for the 380 and 420mm, believe the 80a HW has full telemetry capability. If I remember right the 60a doesn't do mah consumed and the 80 does, no idea why anyone would put a 100a on unless it has more features idk about.

60a esc's are rated for 480mm helis and people smack 550class helis around with 75a no prob, so even a 75a is overkill on a 420mm. 100a is entering the realm of ridiculousness. A $30, 60a YEP could handle the Xnova 3215
930kv for the 380/420 no problem so people must be upping for more features for the Goblins just like the Oxy

Although massive ESC overkill seems to be popular these day in general for some reason. At least with YGE/YEP I've ran them right to their spec'd limits and they barely get warm. Sure they could handle even more but they're spec'd at a number that ensures long term, trouble free operation.

If people aren't upgrading for features, they're just wasting money and adding unnecessary weight.
do you think the 280 series without the one way bearing in between negative and positive pitch with a flat throttle curve wouldn't draw more amps.
seems crazy but I have the 50 amp V3 on my Dominator with 360mm blades before and after and works fine no binding on the goblin either 3rd flight power loss with this quick spin up quickly after..I assume for Safe Auto.
Sounds crazy I know but what would activate a feature like that hobbywing calls it a load soar
