Sir I think I failed to communicate properly again.
I am aware of the fact that Iyer sir has chosen a classic and beginner friendly design for this competition. Also, I am not making any changes whatsoever to the basic construction. I am just adjusting trim tabs and nose weight. I will check reply number 318 once more sir. Also. the elevator tab that I am using has roughly the same dimensions as what you recommended. Its 8mm long on each side and is about 1.5 mm wide.

hitesh kher



Thank you sir i will try for 60 sec up ..
Congratulations Hitesh. a job well done. Your glide is very good, so your CG came out just right. Keep experimenting to cross that 60 second mark . You are so close. You have a good big flying field.  Salute

I just noticed. Very good Hitesh: You are right handed as seen in your second video post reply # 155. your glider in glide test went to the right. Yet in your latest wonderful video Rely # 317 you launch the glider holding in your left hand and rubber on your right. Result is that it climbs to the left and glides to the right. Perfect and good flight. Kudos to you to figure this out. Very nice !
Bravo

@Free Flight,

Hitesh is left handed.

So I set up his models for left hand launch...

In his videos Reply # 155, the first video, a bad stall chuck he uses his left hand. Then in same reply second video he gets a good glide with his right hand. Then his full catapult launches are left handed. Led me to believe he is right handed. Perhaps I saw  the video wrong.

Thanks for setting him up for the left hand pull.

Anyways, bottom line is that he is getting good flights and enjoying. Aiming for a minute that I hope he can soon get it. And all this with an office rubber band, no Super Sport Tan rubber joy here.  Clap

Free Flight sir,

Fooled me too.
Later he told me the right handed long test glide was by an experienced aeromodeller friend! Who helped him with the initial trimming.

Today he told me to donate half his prize money!
A nice gesture.  Clap

Respected memebers of the forum, herewith I have shared the HD version of my latest videos. Has some analysis sfrom my side. One thing that Sunil sir has told me is that I need to launch more vertically. Will do that. I reached 12 sec and 18 sec flight time in the videos. There is also a slow motion shot in there.

Congratulations Karthick. A job well done. Another delightful video from you. Your analysis is good in the video. A few questions that YOU have to find answers to: Why use a very long rubber band instead of more power from two short but parallel rubber band?  You correctly observed and stated that the glider is moving too fast with nose down, not floaty. You went to the right correction of removing clay to move the CG back. But could more be removed? The way to tell that is to keep removing clay till the glider no longer does any transition. Then add back small clay. Do you think it would help to float more if your stab tabs were thicker but very short very near the fuse. These are the experiments to think and do. I am sure you will cross the 40 seconds mark soon by questioning yourself.

In one of your replies you said "Need to follow MY intuition" good, keep at it. That is the key.

Good progress and happy to see the joy on you in the video. Having fun while learning is what matters.

Dear All,

The time has come for you to reach a slightly higher goals of consistent 1 minute flights that is the capability of this model. You guys are now hovering around 40 seconds a little plus or minus and am sure others will soon be there.

I had promised a tan rubber for the utmost three consecutive flights of 40 seconds on a single day with Tan rubber. But your hard work, makes me feel that I will award each of you you who actively participated with the 1/8 inch thick Tan rubber to send your gliders even higher and reach the minute flight.

Working on how to get it to you so please be a bit patient. So Hitesh, S174, Karthick, Weekendflyer, RC Guy please PM me your Email address so I can get in touch with you.

This is a wonderful beginning for you, but you can and will excel soon.

Now then, I have a recommendation for you, if I may please. You have to practice, so you need to build more of the SAME glider. I suggest the following way without balsa except the fuselage.

The technique was created by the world famous Japanese, Dr. Yasuaki Nimoya the inventor of the White Wings Paper Glider. I just made the Lunchbox ( LB from now on) using his techniques and  test glided in my basement. Near my house we have 14 inches of snow so not sure when I will maiden it outside.

 The advantage is that it will a)Most important it will continue to teach you trimming techniques by bending the paper easily and bend it back if it did not work or you are experimenting b) You can build it very fast as all you need is a balsa fuselage, a Manila folder ( available also in India for INR7 or so)  and the manila folder should weigh between 175 to 200 grams per square cms ( Divide weight by area)plus Feviquick and glue Stick  c)With the wing, stab and rudder of Manila Folder , balsa fuse and CLAY weight is around 7.3 grams, not much heavier than your balsa glider today .So the wing loading is very similar.  

I taught myself to fly competitive CLG using his building plus flying technique and have lost many in the thermals. They fly good and will teach you in a relaxed way.

I can volunteer a WhatsApp Video meeting on any Sunday morning my time  ( Sunday evening your time) where I can go over with you the details  quickly (very easy), better than typing many posts here, so you can start immediately.  One of you guys will have to take charge and create this video meeting.


 Next post I am attaching my two videos and two for the White Wings.

Let me know.

Ciao,

@Free Flight sir,

Excellent suggestions.

Here’s a Lunchbox with wings and tail parts made from a disposable dinner plate!

A Very good Question was asked: Can Manila folder gliders be reliable?  Yes very reliable no flex. Proof is in the 10 minute video below. Japanese HLG meet. See how hard they throw, see the launching style and how high they get. No flexing of wings etc. Even the senior guys are throwing hard, no complains from them (Note to myself : do not complain of bad arms).

Talk soon on the Card Paper flying!

A final recommendation. As discussed, if built correctly, learn to trim and transition well. Then tune out the glide. Last, but very very vital,  learn to "pick the air" .

Here the same Lunchbox CLG  made from card paper and balsa fuse. I used a Manila folder for card paper for just proof of concept. Optimization needs to be done . AUW 7.3 grams, can and must  go lower. Card Paper airplanes are good to learn CLG trimming concepts. Once the trimming concepts are understood well, need to learn to pick the air. Finally move to balsa airplane for some awesome CLG fun.

The CLG Mantra: Climb almost vertical, transition with NO loss in height, glide slow with nose slightly up. For right handed people, climb right and glide left.

@ Free Flight,

Great transitions in the video with no loss of height.

Wonder if people noticed that one of my Lunchboxes is of balsa, and the other has the wing and tail parts made of disposable dinner plates of foam!

Regards and thanks once again for your invaluable contributions.

Dear Mr. Iyer,
Thanks for your kind words.

Personally this has been very enjoyable. I think, I learnt more here because of the very good questions asked by the actively participating contestants. These guys made me think differently, that helped me to grow in the world of CLG.

Looking good!

Let's start a Bobni contest. Must ROG, stay with the original design, must use ordinary packaging tissue, use the same diameter prop, must be plastic prop and not home built prop, use the great rubber as shown in the photo. This model was built by most seniors when they were young. and they got started in model airplanes by probably it being their first kit.

To level the field, minimum weight without the rubber at 8 grams.
