Perhaps using gift wrapping tissue paper applied with white glue might smooth out the surface without adding too much weight.

I'm going with 1/4 oz fiberglass on my current big build and it's really very lightweight - I've just had to learn to use a gift card to really squeeze out the epoxy so the weave is showing through. But it does require a pretty flat surface to start with. And it's not too expensive on eBay https://www.ebay.com/itm/272878069574
Thank you rockyboy!
I was thinking to use either this lightweight fibreglass or verry thin fabric.
The problem is that the foam i´m using sucks in the Epoxy.

Tomorrow i´ll try to use the shrinking foil again but i´m going to cut the foil into smaller strips.
The main problem will be the heat of my smoothing iron which melds the foam.
It´s a pretty good iron with a temperature sensor, a digital heat controll and a display but the minimum temperature it can reach is 100 degrees celsius (212 degrees fahrenheit) and that´s pretty much for working with shrinking foil. :(

An other idea would be to seal the surfase of the foam (idk which stuff i can use for this) and then cover it with fabric or fibreglass but that would probably go verry heavy and expensive.

Have a nice day (or evening)!
Hi guys!

I´ve made some progress in the past few days.
First i finnished the secound wing.



And i finished the first enginenacell.





I reinforced the mainjoints with fibreglass.


And fitted it into the wing.


Next i´ll cover it and glue it to the wing.

See you!
Hi guys!
in the meantime i´ve made some progress.
I started with the secound wing connection.
But there i recognised that my leadingedge of my wing is angled up for approx. 5°.

(Picture comming soon)

The onely way to fix that is to cut off the whole leadingedge and glue it on with the right angle. :(
I decided to onely cut of the first 3 thirds of the ledingedge because at the wingtip the angle is right again.


I also attached the Landinggear to the enginenacell.


That´s it until yet.

See you!
Hi guys!
Here´s the progress i´ve made over the weekend.
First i build a holding for the ESC.


Then i fixed the ESC with a peace of Velcro tape.


In the inside of the enginenacell will be a airsream so the cooling of the ESC is cooled.

Next i put a cap onto the bombbay so the content doesn´t drop into the fuselage if i fly a steep turn, a looping or inverted.


I also fixed the secound wing connection.


And i started with the secoung enginenacell.


The Next steps will be to build the enginenacell and to glue the inner wings to the fuselage.

Have a nice day!
Today i build the secound enginenacell and tomorrow i´l install the cowlflaps.


A few days ago i tryed out to cover a fuselage dummy with paper.
I saw this in the F100 build but i decided to use a newspaper couse it´s pretty light.
But i ended up with a pretty heavy and not verry good looking surface (I pained it and it looked a bit like a fleece).
So now i´m searching for a light and paintable material with which i can cover my fuselage without adding too much weight.
Do you have any suggestions for me? (under 80g/m² )

See you!
Hi guys!
I glued on one of the inner wings.


And i put in the cables.


I also finnished the secound enginenacell (in the video from the last post).
And i glued on the leadingedge of the secound wing, which was placed in an wrong angle.

I still have no clue how i can make the outer surface paintable and smooth and at the same time as light as possible!

Please let me know if you have any ideas.

A couple things to think about on the smooth / paintable side. I'm using DAP Lightweight Fast and Final Spackle sanded smooth. 3M also has a Patch Plus Lightweight Spackle that I haven't tried yet, but Wilsonman reports that it sands easier.

I've also got a can of Evercoat Lightweight Body Filler I plan to try soon, but I've been cautioned to try it on a scrap first as the two part poly resins might eat unsealed foam. I've seen people get great results with this stuff on big balsa sheeted wings though.

Then cause I want to prevent hanger rash I've been covering that with 3/4 oz fiberglass and epoxy. The fiberglass is definitely not necessary, but a nice touch. Another top coat option is to use a watered down white-glue mixture and painter's masking paper (you can find rolls of it cheap in the hardware stores paint aisle). I don't think this provides as much strength for the weight, but it's easier to work with.

And for another idea, you can always skip the paint - just sand it down and then apply a low temp iron on covering like the Hobby King line
https://hobbyking.com/en_us/workbench-hardware/hardware-accessories/covering-film.html - Wilmracer used this to put a great finish on his C.460 Caudron build - not sure if he did a filler coat under the covering though.
The problem is that i want to keep the added weight under 100 gramms!
The sparcle is to heavy for that but the covering film is the the idea i like the most.
I already tryed using covering film but it buckled up in the curves.
It´s probably fixable with using smaller strips of covering film.
The foil should also be able to overdraw little scraches.

Hi guys!
In the last few days i corrected the leadingedge of the secound wing.


And i glued on the secound inner wing.

And here you can see how HUGE this thing is.
The carbonfibre rod in the front is 1 meter long (39,4 inch).
After the glue has has dryed i was able to set up everything.


Next step will be to finnish the enginenacells.
