4 meter Plank - Build thread

[thenated0g]

@Mid7night
On my 8ft zagi i made the wingtips out of 2x layers of balsa with one layer of the same 6oz S-glass on the outsides and some carbon in the center to make it rigid. Now they are a lot smaller than what this will be but they are super rigid and strong.

Vertical stabilizer going in the bags.

Can't wait to see the beast at Sunset! I'm making progress on my Raptor too.

@thenated0g - the tail scrubbed up really well - it is all progressing very nicely - I am looking forward to seeing it attached to the fuse and cleaned up!

 

[thenated0g]

Thanks guys! Times running out gotta get this thing done

Left core ready, started getting the fiberglass cut.


Every year at the sunset event they have a free raffle, usually wayne from aloft hobbies gives away a bunch of planes. I wanted to add something to the pile so started working on this:


will get painted and vinyl like this:

 

[bracesport]

you are a good man!

 

[Mid7night]

Ok, I will DEFINITELY be entering that raffle

Along with cutting out full pieces of glass that cover the entire top and bottom i also cut out a few 1.5-2" wide strips to reinforce the leading edge and act as a spar. From right to left we have 80", 60", 40" and the large last piece is 20" but it goes the entire depth of the wing to make the ring join much stronger.



I used super77 to apply all the layers


Now that the foam core is reinforced with fiberglass (much more rigid, i don't have to worry about breaking it) i traced out the top and bottom on the plastic mylar. The next step is to wax (6 times) the insides of both mylars and spray paint the insides of them. Than i will be ready for vacuum bagging.


I also finished up my emergency box giveaway for sunset.

Good progress on the beast - you will be the star of 'sunset'!

I am hoping to do some CF work tomorrow!

Painted the Mylars.


Following Mike Patey's example of cooling his shop down to get more working time i cooled my shop down to about 55 or so and bagged the wings. Made a few mistakes which ill point out later, but it will still be a flyable plank, just some cosmetic issues and things that will cause me some work later.

While that is setting i started working on attaching the vertical stabilizer and making some foam board filler parts for the back of the fuselage. I used epoxy and cabosil to fillet everything and cover the foam board. I will sand that down and put some light fiberglass over that to strengthen it.

I think you need a longer bench

 

[bracesport]

I say go big, or go home!

 

[bracesport]

I am going to have another go at bagging wing - this time one piece with a 13 deg dihedral - I need to upgrade the suction as the domestic bag sealer is not up to the task!

I think I have found some 88g carbon fabric locally ($50/sqm - waiting on the specs to see it is bidirectional weave

Been slowly working on the other wing. All the stuff i showed previously but now mirrored. Also started thinking more seriously about colors think i have a final graphic to go for on the fuselage. The bottom white i am planning on being vinyl to give it some sliding protection.
Hoping my work gets closed so i can get some work on it lol
