So 9contestants for 4 prizes.

Best of luck, gentlemen. Start your flights and post your flight videos.
Remember you are not restricted to one flight.
And that hand launch has a 2x multiple over catapult launch.
Go on posting videos as your flight duration improves.

To get the contest up and running, I look forward to the first video of 10+ seconds hand launch or 20+ seconds catapult launch.

Edit: correction

Glidiator

Will now get down to making the Lunchbox -- following Free Flight's / KK's points very closely.

All parts ready. Was not sure what dope alternative to use. Will try the duco stuff possibly or the polyurethane clear varnish suggested by Free Flight.

K K Iyer

Only to protect from getting wet in the dew. Not essential.

I've used Touchwood before (available in a small tin too).

But will need several hours to dry. Possibly heavier than NC Lacquer.

K K Iyer

Three weekends left.
Enough time to test glide, hand launch to break 10 seconds, catapult to over 20 seconds!
May Diwali bring success to all participants...
Regards

Free Flight

Looking forward to see everyone's flight. Good luck to all.

Wish all of you a very happy Diwali and to your good health.

Regards,

K K Iyer

ANNOUNCEMENT

Deadline for posting video of your competing entry here, extended to 9pm on Monday, 14th Dec 2020.

Further extension is unlikely, as everything has to end sooner or later!

WeekendFlyer

How about a quick recap of rules for submitting entries/video for the contest ?
We all have been busy with constructing and testing the glider  :giggle:
Now it's action time !!!!!

CONTEST GUIDELINES

1. This is DURATION contest for hand launch gliders (HLGs) and catapult launch gliders (CLGs). Propulsion is limited to muscle or rubber band power.

2. Highest duration achieved and video posted here by closing date wins.

3. To emphasise flying, (rather than design, material, construction etc), and to provide a level playing field, this is a ONE DESIGN contest.

4. The model is the Lunchbox, designed in 1975 by John Oldenkamp, a well known American modeller. Selected for its simplicity and ability to easily do 10 seconds from a hand launch.

5. Since access to balsa is a major obstacle, kits are being made available. The kit has everything needed to complete assembly in a few minutes.

6. If you don't need the kit, and want to build it from scratch, the plan is available on Outerzone.co.uk

https://outerzone.co.uk/download_file.asp?planID=11309&FileType=Plan&Filename=Lunchbox_oz11309.pdf

7. If you wish to enter some other design, limit wingspan to 8 inches, and length to 10.5 inches.

8. CONTEST CLOSES 9pm on 30th Nov Monday the 14th Dec. Videos to by uploaded by then.

9. Prizes Rs 1000, 750, 500 and 250 for longest 4 flights.
Minimum eligible duration is 10 seconds for HLG and 20 seconds for CLG

10. Since CLGs can easily achieve twice the launch height of HLGs, duration of HLG flight will be multiplied by 2. I.e, a 10 second HLG flight will be treated as equal to a 20 second CLG flight.

11. Since the prize kitty has to be generated (mainly) from entries, participants have to contribute Rs 250 per entry.

You can post multiple videos, as the duration keeps improving. Only one prize per winner, though  ;D

No limit on rubber band size. Only TAN Super Sport rubber is not allowed, as only 3 of us may have it!



SI74

Prize offered by Free Flight:

"OK here is my prize for the contestants.

For the first person who gets 40 seconds plus flight, three flights in a row , on the same day, and you show it all in a video. l will mail you an unopened packet of the original  1/16 FAI Tan rubber (16 feet long) that I have saved for years. Since you guys are enjoying this contest, I am happy to present this prize to you. I have two such packets, one for me, the other is the prize for you.

Will include a good kit, firm light balsa CLG too. Should be able to mail it in an envelope with no custom duty on your part, I hope.

Go for it, I know you can do it. You are very close, bravo for your experience on a first model. Salute"

Hello sir I read this thread today
Is competition over?
I am interested, but also not interested to buy kit
Can I make my own and launch by hand as you said?
I am interested to build and fly if there is any restrictions of weight and size then please mention that because I am willing to participate.
Thank you.

Himanshu sir, competition is definitely not over. You are free to make your own launch. Iyer sir's idea is to promote deeper knowledge of aerodynamics through chuck gliders. I think there is a design restriction. Only Lunchbox allowed to make it more beginner friendly.

Lunchbox Chuck Glider (best flight 22s)
EaKa-1 WonderTube Trainer- Success!
