Well finally my parts showed up.
SAB told Flying Hobby to ship me a new frame side for free. I had to argue with Flying Hobby for a week to get a 45$ discount on this order... I can't say I'm thrilled about the customer care over there
Anyways, all I need to complete this is now here.
I also purchased a glue gun today (I know this will be needed later on).
The new frame side.
Frames sitting on top each other to check for match. They seem to match pretty good - much better than the old one, that's for sure!
Frame rebuilt, again... Although the frame sides did match pretty good, I had to pay careful attention to the geometry while assembling - it's still a tiny tad skewed, but it levels out after putting on more parts further down.
Putting on the landing struts.
Sweet
Had to fill up some energy (Norwegian chocolate, some Swedish candy and Coke - mmmmgoood)
Battery protection tray.
Assembling belt-tensioner.
The manual does not say whether to use thread lock or not, but I applied it anyways.
I have no idea what use this is going to have LOL Guess it'll be revealed later on.
I have been pondering the pinion choice, or "pinion pulley" as it were, for some time. Gaba's friend's 630 with the Kontronic ESC did very well with the 22T pinion - but as Lee informed me, the Castle ESC is weird when utilizing the governor function; as it wants a rather large pinion.
This is the Castle ESC program, governor setup:
With the included 20T pinion I get 2000 rpm as max headspeed.
With a 22T pinion I CAN get 2300 rpm, but as you can see I get "minimal governor overhead". So the "safe" HS on this pinion would be 2200 rpm.
With a 23T pinion I hit my target HS of 2300 rpm (which the manual recommends for 3D flight).
So I got the 23T pinion.
Attaching motor with the motor bracket.
The pulley is to be mounted 22.5 mm from the bracket surface.
The manual says to cut the motor shaft right above the pulley. This will assure that it does not penetrate the batteries in case of a crash (which will happen sooner or later LOL). I'll do this tomorrow.

Nice Marius,
I'm jealous. Been doing some window shopping tonight. Can't get away from the Goblin though. I see one in my near future
Thanks Lee. There's always something with more bling around the corner. If the goal is to always have the latest model -we'd all be bankrupt
We need another Goblin on the forum Kyle - start selling stuff
LOLThanks Sam. If I could afford it, I'd hop on a plane and come build your bird

Cut off the top of the motor shaft.
Mounting the remaining springs and trinkets on the motor mount.
Swash drivers.
Swash.
The head comes pre-assembled from the factory. I've decided not to disassemble the head to check for TL and grease, as the manual states I do not have to. I KNOW we always disassemble - but I'm taking my chances this time.
Tail assembly.
This thing acts as a brace inside the boom, as well as providing threaded holes on the sides.
When positioned, I glued it into place.
Tail rod guide.
Tail case brackets.
After the glue had set, I mounted the boom supports on the outside.
Mounting tail case.
Assembling tail rod. This could have been made in a better fashion I believe, as it is sort of hard to assemble (tight fit), and feels a bit brittle as well. SAB could have made this thing complete with the threaded rods at the ends - the builder should not have to do this.
Tail servo mount was incredibly tight!
Where there's a will - there's a way!
As the tail servo lead comes out in the same end as the tail belt, there's a chance the belt might damage the wires. So the lead is wrapped in electrical tape, then hot glued to the inside of the boom.
Tail finished.
I have just realized I do not have the servo horns needed for this build! I'll see what I can dig up tomorrow...
6-7 hours straight of assembly - I'M BEAT! Good night!

This is really gonna eat! Already awaiting your first video of this sweet bird!

just watched the video for the 500 and if it is the same as the 630 kyle stacy said the white nylon bolts you were not sure of are break away bolts for the carbon tail boom so it is less likely to damage the boom..... And yes you are rocking this build i agree with canongraphy... i am deff. going to start saving for the yellow and blue 770 goblin man that birds is gorgeous... soon very soon MY PRECIOUS!!!! weezem shall have you!!!! lol

Thank you for the comments everybody

Now this is what would be called the "marriage" in a automobile factory - LOL
Canopy mounts.
I will not be mounting the head just yet, even though the manual says to.
Put on the swash.
The swash got stuck at the bottom and the top of the anti rotation bracket, so I sanded it a bit - smooth as ice.
Goodbye JR
Hello Goblin
It took me some hours, but I got hold of some servo horns. I needed single horns, I could only get multi - but I'll make it work. Here I'm finding 90° on my servos.
Cut off the remaining arms.
Sanded them round.
The manual does not state what servo goes where, so I noted down where I think they should be...
Servos mounted.
The horns could have been a bit longer as you can see - but they are within specifications.
The ball is about the right length - could maybe have been a bit shorter if it was to be 110% perfect.
As you can see, I took off the swash before mounting the links. These links were hard to snap on, so it was much easier with the swash out of the way.
Powering up to check for level swash.
Swash level right off the bat - that's a first!
ESC mounted. Used four zip ties and one velcro strap.
At this point I make a mistake. As I read through the next pages, I make myself believe it's a good idea to wait with assembling the Rx/Gyro platform. What you want to do here, is mount the three pins - and leave out the platform itself for later. JUST MOUNT THE PINS.
The reason for me not mounting the gyro platform is that I saw this is to be mounted next. This is to be mounted UNDER the platform -so of course you don't want the stupid platform in the way. But again, I should have mounted the pins.
These are for mounting the boom.
This tool was included in the kit. It is for tightening the boom to the frame.
Mounted the tail belt. This is a mistake - I SHOULD HAVE MOUNTED THE MOTOR BELT FIRST.
Mounting motor.
And this is the point where I realize I should have mounted the motor belt first (not able to mount belt because the tail belt is in the way).
Another mistake. I should have slipped in the motor belt before I mounted the motor.
Motor- and tail belt mounted.
Aaaaaaand this is the point I realize I should have mounted the pins for the gyro platform before installing the boom...
Crap.
This is the point where I'm realizing I'm super tired and cannot do anything right - so I'm calling it a night. Maiden tomorrow?
