FPV49 v4 custom
#1
Hey everyone,

I'm here to introduce to you my first ever Depro-Scratchbuild flying wing.
I never had a flying wing nor did a depron build, so please give me your advice!!!

I took the planes from a norwegian forum where FPV-Trond introduced them.

The electronics:
- Turnigy TGY-777 Slim Wing DS/MG Alloy Case Servo 5.5kg / 0.10sec / 23g
- NTM Prop Drive Series 35-36A 910Kv
- TURNIGY Plush 40amp Speed Controller
- FrSky X8R-SB (The one i won from Oscar ^^)
- 2x ZIPPY Compact 3700mAh 4S 25C (so 7400mAh 25C 4S)
- PZ0420M 600TVL Sony
- CC3D (wanna test beta/cleanflight for planes)
- vTX: Don't know yet. Maybe it will get the 600mW from my Armattan F1-6 (and this get a new raceband vTX)

You will see that i try to modify it, i hope it works.

If you have questions or suggestions feel free to write!

BuildLog:

18.01.16 Started by tring to find the mid of my sheets because the were 2cm short.


The first cut out part ... damn big those 120cm
Left the rear for the "mod"



20.01.16 Finally cut out all the sheets ... and they fit okay ... like 1-2mm off. for the first time i'm okay with it.
You can see i left a straight line like in the version 3 of the FPV49.
After i get my motor attached and my electronic bays cut i'll cut it down.




29.01.2016 Glued it together ... okay i made big mistakes. My whole building room smells like Uhu Por and benzine.
The i had nothing to press it against and when you put the sheets together the are not movable.
So I hat to pour benzine between the sheets to loosen them again ... shit work, still messed it up poorely.

Put in two carbon tubes 6/4mm (about 70cm) in the leading edges and one 12/10mm (100cm) as an "A-spar" over the motor mount (you can see it some pictures below)

See yourself:




Next up i beveled the front edge. I got rid of some of the bad glueing.
But still i had to adjust cut the trailing edge. 

30.01.16 Started cutting out some space for LiPos and the other electric components.


If you look closely to the bottom of the picture you can see the Carbon tube.



I found out that the fuselage/wings are not really dry yet (maybe cause i had to loosen the sheets up with so much benzine :/ )
So i will let that dry out some days.
So i have some time to do the control surfaces.
Most people suggest to make one spar of carbon long into them. Sorry guys, but that's not helping with torsion.
So i just put it in like the photo below. It still cen bend (but it will be attached to the fuselage) but it won't twist. And there is the whole point of it imho.

01.02.16 one of the control surfaces




So that's everything for now.
I'll continue whe i have some time left, atm my job is very time consuming.

Cheers
Diego

That looks sweet!  Nice build so far... please keep up the pics.

I love wings.  I learned to fly on an Assasin.  loads of fun, fast, agile and quite crash-proof.  I have several types and building wings is what got me into scratchbuilding.

Formation flying, close proximity, combat... let me see ya try that with a quad!

To anyone thinking about flying wings:  Just do it!  Build it, Fly it, race it...  and then build more so your friends can fly with you and you can knock them out of the air!  Angel

Post any questions or comments and I'll see what I can do to help.


Blue skies, Brother

FPVTrond did an amazing job with the plans for the FPV49 series of flying wings. I built and flew two of the v3's and they were just awesome! I crashed the first one because a servo linkage came loose. The wing did an amazing death spiral into the pavement....foam was everywhere, lol. The second v3 was stolen from me....very unfortunate. I'd like to get another set of FPV gear and bulid this v4. I really enjoyed flying it.

So far, your build looks very good and your choice in electronics looks very good. Best of luck with the rest of the build and with the maiden flight!!!
ZMR250 FPV Racing Quad with 5.8ghz
HK Skyfun with ImmersionRC 5.8ghz 600mw vtx
Scratch built foamboard canard with 1.3ghz
