RC India

Friends..Colleagues..
a real way to get excited is, refueling the tank, or recharging the battery pack,and run to the maidaan, before 5.30 AM, and fly in a manner of scream...flat..emmelman..knife edge..s roll..falling leaves...
or, fill the tank, or charge the battery pack, look for a good time to get shades..and release craft in to water..and enjoy the sheer natural show offs of the crafts...
but nothing is going on as the heavy rain is going on..out side..
so its the time to think about some thing indoor..so, i decided..and made an ornithoper within 30 minutes..all with handy things around me..even i wondered as i finished it.. :bow:

sorry for the multiple postings..my connection is too slow and basic..soon i will change it in to 3G..as our nearby tower installs... :banghead:

i searched along my rooms for some stuffs...and got some balsa strips..shifted from my earlier project works...

i took some strips...

and took a motor gear assy, from an old scraped heli..tail rotor...a perfect EP 120 combination..

time to fix a cam on it..more clearly a crank..is from a piece of bicycle spoke..

i took nothing as a calculation, but all from my previous experience...
start to build..the main mast..all with drops of super glue..

so the tail structure..in detail...i reinforced it with some struts..in addition...

thanks for the balsa..light weight..

adding a cross post to hold the flapping hinges...

hinges..time to find some ball head pins..i took these all from super glue packing..have ample..

so time to fix flapping arms..

showing the BDA of the flapping mechanism..

showing the TDA of the flapper..in this position both stroke setting was almost same..but later i alter the port wing, in to less, to get a circular orbit in flight.. :giggle:

reveals the tail plane structure..i gave a slight inclination to get a circular orbit..

time to apply tissue..i got this type of tissue, from our depo..its a crape like tissue..

and finished...it took about 15 minutes..almost..

showing various angles..

Nice work !! ... does it fly well ? eagerly awaiting flight video ... :)

Buzz..fighting with connection... :giggle:

and time to find a battery..no more to think..scrap one from any of my helis..

showing underside...

and moment of happy...at first she showed some erratic nose down attitude..but i displaced the battery to tail side, and especially to port side, to get a circular orbit..and not fast..but flies..nicely..a great satisfaction...nothing official about it..ahhaaa... :thumbsup: :giggle:

it is not possible to upload a big file from my connection now..so i am uploading a small file..and will shoot a good video at day time..

Friends..i posted this here not to show, anything, and not to boast..but you can see how simple is to make a craft our own..its nice experience..

Wow!!  :o Simply amazing !!!  :thumbsup: {:)} :salute:

Buzz..nothing amaze..anyone can do...we call this ideas in our native languages as "POTIKKAIKAL" means, some 'HANDY TRICS"..and nothing is extra ordinary..you can see how simple is to make one..and sorry for the bad photography, because i cant move very faster, with my body, because of my bad health..but i will shoot a good video at day time..and i hope many of us will try once..and its my sweet ORNEEE... :thumbsup: :thumbsup: :thumbsup: :giggle:

How did you manage to rotate this Ornithoper in such small circles inside the house? How did you control this?
Your Radios are well maintained! saw them in the background. Also the engine on the table . do you intend to make a boat of it? That would be intersting.
 Did you try your Futaba for a submarine application.


Shreekant

nice work.. anyways take care of your health also . so what happened to your health?

Rooster..i shifted the driving arm, of the port side, and displaced battery in to port side..tail also bended a little..and no any critical calculations..at first it worked too erratically..but i balanced it with battery..and added one more pin at centre, and at front cross bar..and by tomorrow, i will make it even better, for a good flight...

Pratheesh..i got an accident..cant walk freely...its ok..

you are from kerala right? which part?

Not clear roopesh! maybe a flight in the open would be good to observe.

yes..my native is Kerala..God's own land..
Rooster..i use all stuffs to all..i make all types of craft..its a pleasure..and now earnings also..

i will shoot a good video at daytime...and have to reinforce the joints once again...

and also have to rework on wings..altitude is losing fast..so, i hope i have to fix a wing with more area..and a big tail..and afraid, that wont fly straight..hi..hi.. :giggle:

Hi Very nice Built...Where did you bought that kds radio and for howmuch you bought it...How is the performance?

thats the most creative thing i have ever seen..

Great build Roopesh sir, you've become an inspirational figure for me!  :bow:

 :bow: :bow: :bow:
Hail!! This is something!!! on of the few great DIY thread I noticed in the recent times!! You would definately inspire many people to attempt the same, like Ashta's Quad set a new precedence!!

Yes, please give a plan to build if possible, with required material.
Will be a lot of help for those who cannot build anything (like me) without foam and cf  :banghead:

Congrats Roopesh, one more mile stone!!!  {:)} {:)} {:)}

Friends..its nothing..and not a perfect machine..and all you can see the steps from my postings..and i will make it better by working on it..and will fix a radio, from a little heli, so i can avoid crashing it on walls...and now i am in a little trouble, that its not flying in a straight line.. :giggle:..and we do not need any plan as you can see, now just need some practical experience..all you can see none of my models are from plan, and from my imagination..except the scaled crafts.

When it is flown without RC, then definitly will have a better control & result with RC.  :thumbsup:

and million thanks for the wishes..and care..Chkalyan ..i bought that KDS 7 ch radio from Bangalore,at the rate of 6500/-Rs, include 4 Hitech std servos. it working nicely, and in my inspection, the internal parts resembles the most Chinese units.but in my experience the old 4 channel Futaba is the King... :thumbsup: :thumbsup: :thumbsup:

yes Maharana..by night i tried to shoot some more videos, in straight line..but it crashed in wall and broke its flapping arm..and will make it worthy... :giggle: :giggle: :giggle:

good one  :salute: :salute:

thank you Dini..and i shared this here not for a boast..but i expect many from you all..so our knowledge will increases..and yes creativity..so our Form..because all we are RC INDIANS... :hatsoff:

Very nice build... :thumbsup:

seems like tied from to the roof from threads

Vineet..i will rework on it some..and will add a radio..then shoot a good video..sure...

good work ...it took me more the 2 weeks to built mine ;)

Joy..by this night i will replace the tissue with colorful one..and yes bigger..with bigger tail..and will add a radio..and hope will fly nice and straight...but here rain is going on..ohh...

This may be of interest to those who have been following this thread.

Great, Great , Great..
very very nice roopesh sir...
 :hatsoff: :hatsoff:
 :bow: :bow:
a simple , basic built sir...
before seeing this thread , i was scared of ornithopers and i hated them due to there complicated mechanism....
actually , really say, i was not interested in seeing this thread as it has word ' ORNITHOPER'.
Now , after seeing the thread , i am really interested in constucting such bird...
and
keep yourself fit and fine sir.....

Great built Roopesh bai, really a great one...... {:)} {:)} {:)} :hatsoff:  Please post some outdoor video also.

It looked same to me as well.

Rooster..dont panic..none of my work is a claim..but i am studying a lots from my modeling works..my first ornithoper was in 1989, in my academic years..and was powered by a simple rubber band..it flown well..but the vicinity was the Gymnastic stadium at Thalassery..but now think about our convenience in modeling..so, at present i am working on a new ornithoper, big, and fully radio controlled..so, i am studying a lots on it..and i am too thankful to Sushil Sir, for the link..and thank you all for the inspiration to make even better one..and thanks for taking inspiration from me..its a great award for my birth..and will post a good video, after clearing all technical problems..it was a crude machine, and was flying only in circles..but giving up is not my option...wait a little..please..we must make it..

Adithya..dedication and patience are the key of model making..i learned it from my GURU, Sreedharan Sir, NCC Instructor, and it was a stearn training..no give ups..now you can see how simple is to design a machine..try to make ample of various crafts..

Sushil Sir..a million thanks once again for the links..and please ask me any help that i can do for you..its a pleasure... :bow:

Awesome Build Roopesh, you really made it look very simple  {:)}

Thank you Amit..thank s for the inspiration..

good luck....

Good morning ..and thank you all..by last day i managed to make an even bigger one..all with bamboo strips.was tied up with my project works..and will post all details..so, all you will get how simple it is..and how nice it flies..give me a little time.. :salute:

So is it tied/hanging from the ceiling or not  ???

Sun..i will repair the same machine..and shoot a good video on day time..its simple.. :thumbsup:

It was a very simple and honest question, i was kind of expecting a Yes or No answer. Any way never mind, have fun  :thumbsup:

Sun..thanks for the inspiration..give me a little time..because i need some good mood to work on this simple machine...

agreed

+1

Well, I don’t think any wrong there; Roopesh has already mentioned it as non-rc version.
While testing it crashed and yet to build a new one with rc. These things happen / usual while undergoing these experiments.
And also I will feel proud if I build an Ornithoper even a hanging one.

No strings attached, SLS? ;D

We know it , just asking , never means to disrespect any one . go on roopesh.

Control line or no Control line this is really a nice one.

Good job buddy.


Thanks for the link sushil_anand, love it.

Hai Friends..back here..i lost my Ornee after some deep circles, crashing my wall..after my accident, a fast movement, or hurry is not possible..and yes because of my excitement, i made it crashed..so, finding a radio is a must.. >:(

so, i scraped a micro radio, from my little heli..based on PWM its a nice one..

so i made a new ornee, even bigger, and powerful with a new gear box..

gear box is changed and its too powerful..

the radio receiver and battery are too light..

Friends..and Colleagues..now she is flying nicely..very nicely..with a great FLAW...she climbs in a steep angle, and in deep circles..at beginning i thought it was because my adjustments..but now i realizes, that some thing wrong happening in my design...it circles to port wing side...
friends..and Colleagues..instead of making fun..can anyone advice me to rectify this problem once..?
because i have to make this fly in to a correct and perfect one..a straight flying one...i tried with altering the tail plane..attitude..but still persists..
please give me any advice about this phenomena..but i never give up..this is the time to think about Write Brother's history..success at last..after hard efforts...
so, please help me..once.. :help: :help: :help:

sorry..adding a long view of the new machine..

advices..tips..guidances.. :banghead: :help:

Drop (several full stop)... and write complete sentence insted of SMS type.

It's rule of this forum.

In all ornithopter forum or post it is clearly written that the flight control is made by tail control like rudder and elevator. Some turnings may be adjusted with back of wing center shifting. Actually it control the pitch of the wing during movement I think and creates differential thrust. Just search RC Ornithopter in youtube and you will get lots of stuff.

In RC, it's easy to adjust CG but make it a rubber powered and you will realize the adjustment process. Extra will be Torque and time/duration to be take care off.

Good morning, and thank you Kalyan.i will go for a good study, and try with a rubber band powered one..thanks for the valuable points. :thumbsup:
