75" 3DHS Edge 540 V2 Assembly Thread.

Never quite sure where to start one of these threads, so here we go! I'll edit this page as I go. I've already started to build this, so I'll be adding pictures quickly.
My build is looking like this:
Motrolfly 4330-216kv

XL Blazing Star Standoffs (Had to ream out the X mount holes to use this)
Castle Creations Edge 80HV
Futaba SBS-01C Current Telemetry Sensor
Futaba SBS-02G GPS Sensor
12S setup, two 6S in series.
Falcon White 20X8
Extreme Flight Carbon 3.5" spinner
MKS777 for the tail (had laying around)
MKS777A for the wings (also had laying around, but only because old style doesn't fit in the wings since they are too tall)
Pulse 2S 1350mAh for the RX
Futaba 18SZ
Futaba 7008SB

Here is a link to the maiden flight:

Here is to what I'm sure is everybody's least favorite part about putting an ARF together. Hinging. I'll share what at this point seems to be the quickest method with good results.
First, I'll make sure each hole is clean of any obstructions and allows the control surface to deflect without binding. I must say that 3DHS/EF did an excellent job prepping this. They burned each hole so it's pretty clean, and left very little touch up work on my end... awesome.
Then I'll scruff up each pin with a little coarse sand paper for good measure.

Next is the most satisfying process that I learned from the forums. Get a old barley soda can, cut it in half (cuts easily with an Xacto blade), wash it off. Flip it upside down. Put some petroleum jelly in it (Vaseline is the name brand Petroleum Jelly). Heat it up so it melts.

Bend each hinge pin in half, dip it in the molten Petroleum Jelly, fold it the other way, dip it again, work the hinge. It will start to clump up when it cools off. When it's hot, it seeps into the cracks of the hinge, once it starts to cool off it will build on itself creating a protective shield against the epoxy later on.

Then set the prepped pins aside for the next step.

Then the "fun" part. 30Min epoxy one aileron at a time. I use a small mixing cup, and a round stir stick for mixing rod finish. If you need another minute of working time, spread it out over some aluminum foil to delay the cure time.
The dowel/rod fits in the hinge pin holes great. I cut up some paper towels and have some lacquer thinner and denatured alcohol ready for the cleanup.
I get the mixing sticks here:
