I needed it to lift my spirits up. Title: Re: Biplane : Model 5 Post by: Swapnil on July 21, 2011, 10:21:00 AM Good one! :thumbsup:

Title: Biplane : Model 5 Post by: naatumach on July 21, 2011, 12:51:53 PM I used all the basics in building this a/c and im very happy with the results
1. Used an airfoil 2. Proper aspect ratio 3. Fully enclosed electronics 4. All weight concentrated at 1/3rd Line Title: Re: Biplane : Model 5 Post by: Swapnil on July 21, 2011, 12:55:22 PM Wow, looks like a hungry shark!
Title: Re: Biplane : Model 5 Post by: naatumach on July 21, 2011, 01:26:02 PM Thats the jist :) vintage decals with a hint of tribals
Title: Re: Biplane : Model 5 Post by: sunk? on July 22, 2011, 04:19:40 AM hi mate.
looks good.....is it a 'slow flier'? I am looking at doing a fairy swordfish..............had the plans for a few years now. regards don Title: Re: Biplane : Model 5 Post by: vineet on July 22, 2011, 08:46:18 AM hey bro just go to near by ground and make some footage , cant wait to see it flying .
Title: Re: Biplane : Model 5 Post by: ashJR7202 on July 22, 2011, 11:27:03 AM nice build!!!!
put some wheels for ground clearance otherwise ur prop will hit ground while landing!!! all the best!!! Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 11:35:58 AM WOOOWWW...naatumach...its so nice..and simple yes...your work inspiring me a lots to make a BI...thanks for sharing this effort..and yes sure please post a nice video here..awesome...indeed from simple materials...
Title: Re: Biplane : Model 5 Post by: ujjwaana on July 22, 2011, 02:07:52 PM Woww!! this is a nice build!
Since you are using non laminated bio foam, see if you can tape the leading edges with clear scotch tape to save nicks from landing. All the best for the maiden. Title: Re: Biplane : Model 5 Post by: naatumach on July 22, 2011, 02:23:01 PM Thank you all...
Sorry the plane broke, i cant put up a video. It flew only once. The problem is that the motor is just strong enough to pull the aircraft straight without any strong winds. I have a 135W motor + 20A esc + 8060prop Till i go back to college and save money to buy a stronger motor, 30A esc, prop and a new battery,total of around (Rupees 2500), my rc is under hibernation. It was a slow flier and that one sortie was a lot of fun i was able to make one whole circuit of the ground. @ashJR7202 : sir i did that after i fixed the crash, but the a/c didnt have any strength to pull up. Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 02:28:07 PM oh noooo..please make her flyable...
Title: Re: Biplane : Model 5 Post by: naatumach on July 22, 2011, 03:27:44 PM I have decided on a motor and it would only cost me Rs825.00 + cost of props.
But i have only 6days left at home so there is no chance i can get the shipping done and still be left with the time to work on it. Sorry people. Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 03:48:05 PM ok..but keep it in mind...and your work inspired me a lots..so within this time i managed to make a pair of wings...after many years..i am back in to aeromodel making..but friend..back pain is intense..so need some rest..and sure your work is too inspiring...because it is simple...
Title: Re: Biplane : Model 5 Post by: naatumach on July 22, 2011, 04:00:12 PM and you have "ALL" have inspired me to take a chance of buying them in such a short span of time :)
@roopeshkrishna : get well soon :) Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 05:03:55 PM yes..because..Naatu...biplanes are simply...irressistible...ha...ha...thank you...
Title: Re: Biplane : Model 5 Post by: Swapnil on July 22, 2011, 05:14:29 PM Vaibhav, if you don't mind me asking, what does 'naatumach' mean? :)
Just curious 'cos I saw the same user-name on roboticsindia, dailymotion, indianguitartabs, moneybhai, splutterfish etc. Title: Re: Biplane : Model 5 Post by: naatumach on July 22, 2011, 09:13:58 PM naatumach doesnot mean anything its just my pseudonym. I have always had it, my dad made it when i was in seventh class, he makes really cool and unique pseudonyms.
you can find more deviantart, google, 3dm3, fb and lots that i cant even remember. Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 09:28:46 PM nice...hi...hi...then, will it say as nattumakkk..or nattumach..?
Title: Re: Biplane : Model 5 Post by: naatumach on July 22, 2011, 09:31:12 PM yes. its pronounced with a 'k' and not a 'ch'.
Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 22, 2011, 09:37:11 PM thank you naatumach..cool name...
Title: First Flight: Biplane : Model 5 Post by: naatumach on July 26, 2011, 06:07:57 AM It flew! *dance-dance*
After lots of glitches. Finally i strapped on the 260W motor and flew it. Here's the flight log. Launched at 65% throttle. It climbed. Went pretty far ahead. I did a little maneuver. Then I got too excited and wanted to land it, so i foolishly cut the throttle and expected it to glide back. I didnt throttle again because it was just above the ground and i didnt want to damage the prop. So it landed with a thud. Because of which a wire got loose on the inside. I came back fixed the wire. Posted this message. Now im going back out again to find a camera man :) I have the video of the maiden flight. Will post it after this flying session. happy landings :) The image has been photoshopped, it elevator is the new one and its shadow shows how it looked before i cut it. Title: Re: Biplane : Model 5 Post by: Swapnil on July 26, 2011, 06:14:04 AM It flew! *dance-dance* ... Awesome! {:)} I wish there was a dancing smiley for such occasions! ;D waiting for the vid... Title: Video: Biplane : Model 5 Post by: naatumach on July 26, 2011, 08:13:29 AM Sortie 2 and 3
I really need to learn to land. Good sorties :) I am flying low for the sake of the video. This concludes this vacation's RC build because the 260W motor melted the battery's wire and caused the originally loose wire to come off the battery. http://www.youtube.com/watch?v=ejzsGMJm7So Title: Re: Biplane : Model 5 Post by: Swapnil on July 26, 2011, 10:07:30 AM Nice flight! :thumbsup:
Wish I had a ground like that around here! Title: Re: Biplane : Model 5 Post by: vineet on July 26, 2011, 11:07:30 AM good man :thumbsup:, make another video of high flying with a good cam.
Title: Re: Biplane : Model 5 Post by: naatumach on July 26, 2011, 01:07:23 PM Thank you... sorry cant make another video, i have no battery. I need to buy a new one. This battery is unserviceable and i am apprehensive of digging in because of all the stories i read about exploding LiPos
Title: Re: Biplane : Model 5 Post by: roopeshkrishna on July 26, 2011, 01:17:52 PM NAAATTUUU....awesome...heeeyyyy....its even more inspiring...thanks for sharing...
Title: Re: Biplane : Model 5 Post by: Swapnil on July 26, 2011, 05:06:41 PM ... and i am apprehensive of digging in because of all the stories i read about exploding LiPos Don't be! I turned a brand new 3s into a 2s for using in my Tx by ripping one cell out. You just need to be careful enough that's all! Title: Re: Biplane : Model 5 Post by: rcpilotacro on July 26, 2011, 06:21:06 PM Naatu , good build, some more streamlining probably ? Food for thought..
Title: Re: Biplane : Model 5 Post by: naatumach on July 26, 2011, 06:57:42 PM Yes sir, definitely. This build's motto was no loose wires.
I want to build something like your skywalker. i would love to try a balsa build. But i dont know how to make a balsa a/c. I have seen a lot of pictures but i am looking for more detailed tutorials. Title: Re: Biplane : Model 5 Post by: vineet on July 26, 2011, 11:36:38 PM today i just ripped off one cell from my 3s 1800 mah zippy pack as the battery got bulge , now it is working fine but less throttle as i am now gettin 7.2 instead of 11.1, but the thing is now the battery is not warming at all even on the full throttle as before it was getting dam hot on full throttle , and even looking very nice .just be carefull on balancing plugs and while soldering.
Title: Re: Biplane : Model 5 Post by: naatumach on July 26, 2011, 11:45:50 PM After Swapnil's post so i fixed my battery. Its good to go. :)
Tomorrow morning i'll go for my sailplane's maiden. Title: Re: Biplane : Model 5 Post by: Swapnil on July 27, 2011, 10:06:24 AM Did you record the sailplane's flight? Eager to see it! :)
Title: Re: Biplane : Model 5 Post by: arunh on July 27, 2011, 10:20:02 AM Hey Naatumach...
awe inspiring build and fantastic flight - aptly aligned to your signature -- build fly modify.... Way to go.. Cheers, Arun |
