hello everyone! here i'm again with my 3rd entry to the 2015 sweepstakes. this time its 1903 wright flyer scratch build with actual wing warping.... i was out of station for few days , that's why i'm late in posting and will continue the build from today onward..
since i was unsuccessful in getting plans for this build so i will have to figure out the dimensions to build this awesome flyer, though i have taken references from many google images...
so for this build i'm going to use 3mm depron , barbecue sticks, carbon rods, clear tape , glue and some miscellaneous stuffs (will figure out later)..
i started this build on 2nd July 2015.

yesterdays progress:- (15th July 2015)
the most painful and time taking process was to connect the wings as it took me the whole day to do the thing properly and now its all glued and its symmetric with 10cm gape throughout the wings...
(https://lh3.googleusercontent.com/--7pthR2n04s/VafGDB1SRrI/AAAAAAAAAms/aQu7s1uIe4Q/s1280-Ic42/17.JPG)
measured and poked some holes near the wing ribs where the sticks will go...
(https://lh3.googleusercontent.com/-SyISd-61Me0/VafGDXfLA9I/AAAAAAAAAmw/L-hkLAhqUvs/s1280-Ic42/18.JPG)
took 8 2mm carbon tubes and 10 barbecue sticks. they all are 10.6cm in length ( since i want 10cm of gape between two wings and my wings are 3mm in thickness so, 10cm+0.3cm+0.3cm=10.6cm)
(https://lh3.googleusercontent.com/-xI5jedMB8Bg/VafGDuE1jLI/AAAAAAAAAm0/wBGohtptsz0/s1280-Ic42/19.JPG)
completed wings.. these are 10cm all around symmetric...

some updates from 16th July 2015:-
while the wing is all glued and done, its time to build the wing warping mechanism..
took screw hole part from a 9g servo protector and glued it to the wing which will act as a connect point for the servo push rod.
(https://lh3.googleusercontent.com/-dQ1tWediQcA/Vav19kicE7I/AAAAAAAAAoE/3Prflp6lBv4/s1280-Ic42/25.JPG)
(https://lh3.googleusercontent.com/-j9jsDByl38c/Vav13OOTC0I/AAAAAAAAAn0/rtBwZe0Igjo/s1280-Ic42/26.JPG)
made the hole to mount the servo in place...
(https://lh3.googleusercontent.com/-e3-IxRW7rp0/Vav14UUE_UI/AAAAAAAAAn8/C4QNdjsP96s/s1280-Ic42/27.JPG)
servo mounted. i'm using micro servos for this build..
(https://lh3.googleusercontent.com/-j9oAk5D9Mu4/Vav2L9xJFuI/AAAAAAAAAoQ/uVNel77QHpY/s1280-Ic42/28.JPG)
glued a carbon strip at front for strength because the wing will bend at that point..
(https://lh3.googleusercontent.com/-Xda3B5tmSmc/Vav2MTyxZAI/AAAAAAAAAoU/N3LQl9WFVug/s1280-Ic42/29.JPG)

when the servo push or pull diagonally, causing the wing ends to warp... will post a video of the wing warping at the end of the build... for the time being wing completed..
now moving on to the frame..
starting with the back rudder part...
used these parts..

(https://lh3.googleusercontent.com/-YxsCPAfL9IU/Vav2t5y-41I/AAAAAAAAApE/kCAySYhrfjo/s1280-Ic42/35.JPG)
also glued 4 servo protector parts at the front and back of the wing to connect it to the frame.. it will also be a removable wing build since i face problems taking my fully glued planes to the field...

Very nice piece of craftsmanship.
BTW what glue you are using.... doesn't look like fevicole?
for depron purpose i use synthetic fevicole (i think this is what its called) its similar to fevicole but much cheaper (250g for rs20) and dries much much quicker then fevicol.. and for the other parts i use dendrite and super glue..
update:-
frame build continues,
bottom of the frame-

;D thanks... :thumbsup:
thanks rcrcnitesh :hatsoff:
Super cool
Good job, keep it up!
thanks...
This is some feat of engineering going on here Jayant.... Super build.. Well done!
What I find particularly commendable is the conceptualization involved prior to the build
:salute: Jayant
ohhh man... thank you very very much b4ggu sir and sanjay sir... model is almost complete but the weather here is not suitable for flying.. heavy rain from past few days but hope you will see the maiden soon........
Looking forward to it. 👍
completed the model but unfortunately crashed it (it flew for 4 sec i think) ... :banghead: :banghead:
couldn't take the flight/crash video but I'm here to show you the model before the crash and after the crash and also the video of wing warping..
I'm really frustrated right now but i don't want to leave my post alone and incomplete.. >:(
so here i go...:-
completed model:- (wheels are added for easy take-off and landing and added some strings to get the effect of cable as in real Wright flyer)

so that's it guys.. hope you enjoyed the build, i will build the upgraded version of this mode because now i know the weak points of this model...
i'm sad that i couldn't apply this model for the sweepstakes but i'm happy that i got a chance to create this amazing flyer and share it with you guys.. :)
Saw the post regarding the crash today. Really unfortunate but nevertheless a wonderful build. Eagerly waiting for your repeat build.
What was it that caused the crash?
