Hi everyone,
Wonder if anyone would be interested in attempting a one minute flight with an unpowered, RC/non RC, Chuck glider/catapult glider/discus launch/ rubber powered model, if some prize was offered...

If at least 10 members are willing, I would consider putting up a prize of say Rs 5000!

Come on guys.

Please see reply #12 for details

Here’s an example (that unfortunately I can’t match)

The Kremer prizes are a series of monetary awards, established in 1959 by the industrialist Henry Kremer, that are given to pioneers of human-powered flight. The competitions and prize awards are administered by the Royal Aeronautical Society's Human Powered Aircraft Group.[1]

The first Kremer prize of £50,000 was won on 23 August 1977 by Dr. Paul MacCready when his Gossamer Condor, piloted by Bryan Allen, was the first human-powered aircraft to fly a figure eight around two markers one half mile apart, starting and ending the course at least 10 feet (3.0 m) above the ground.[2]

The second Kremer prize of £100,000 was won on 12 June 1979, again by Paul MacCready, when Bryan Allen flew MacCready's Gossamer Albatross from England to France.

A Kremer prize of £20,000 for speed was won in 1984 by a design team of the Massachusetts Institute of Technology for flying their MIT Monarch B craft on a triangular 1.5 km (0.93 mi) course in under three minutes (for an average speed of 32 km/h (20 mph)). Further segments of a total prize pot of £100,000 were to be awarded for every improvement in speed of at least 5%; the next segment was won in the MacCready Bionic Bat with a flight of 163.28 seconds on 18 July 1984, piloted by Parker MacCready.[3] The third segment was won by Holger Rochelt flying Musculair 1 designed by Günther Rochelt. The fourth segment was won on 2 December 1984, with a flight of 143.08 seconds in the MacCready Bionic Bat piloted by Bryan Allen.[3] The fifth and final segment was won by Holger Rochelt flying Musculair 2, after which the prize competition was withdrawn by the Royal Aeronautical Society on grounds of safety.

There are currently three Kremer Prizes that have not yet been awarded, for a total of £150,000:

26 mile Marathon course in under an hour (£50,000),
Sporting aircraft challenge stressing maneuverability (£100,000),
Local challenge that is limited to youth groups (under 18 years) in the UK.

Perhaps a 1 minute flight with a hand or catapult launched glider is not even worth attempting...

Hi,
Only six interested so far.
I guess a one minute flight from a hand launch may be too ambitious.
Let me simplify.

Target: 30 seconds flight (with supporting video)
Model: Hand Launch Glider (no engine, no motor, no prop, no catapult, no histart, no towline)
Closing date: midnight Sunday 1st July 2018.

Prizes:
1. HK T4A V2 Tx/Rx (unused) or Rs 2000 for the first HLG flight of 30 seconds or more posted on this forum after midnight today
2. Rs 1000 each for next three ...

If there is enough interest, will try to sponsor more such contests within my limited means...

Edit
Hand launch includes javelin, side arm, discus and tip launch!

Prabal, Taksh, Kanav, Imperial Fire, Rooster, Gaurang, Kalyanda, Kiran
Welcome on board.
This weekend is a good time to build a new model or repair an old one.

Please post pictures of your build and videos of test flights as you go along.
May hopefully attract some more members...

Sir, intially you did allow rubber power and catapult. I think 30 seconds with a hand launch is really tough. Even the world record is 29 seconds on a paper plane. I think catapult and rubber power should be allowed.
DLG may be a option.
some chuck gliders do achieve 30 seconds but what i mean to ask is cant catapault be included?

I think 30 seconds with a hand launch is really tough.
No doubt a challenging target. But 55 seconds, that too indoor (in a hangar) was achieved in 1941!
I had organised a similar contest in Delhi in 1968. At that time we used to get about 10 seconds, so the target was 15 seconds. And the prize was Rs 10!


Even the world record is 29 seconds on a paper plane.
I never said you have to use a paper plane. I expect balsa and/or foam/glass/carbon composite models. The video posted by Rai sir only shows that even a paper plane can do over 20 seconds

I think catapult and rubber power should be allowed.
Postponed for the present due to lack of availability of rubber and props

DLG may be a option.
It is. But free flight, not RC

some chuck gliders do achieve 30 seconds
Here’s a 20 second flight video of my model launched by a friend


but what i mean to ask is cant catapault be included?
Presently excluded due to difficulty of standardising the catapult

This challenge is not impossible. Make an attempt. Make several attempts.

Excellent  Clap
Exactly the kind of attempt intended.
With this model I could probably exceed 20 seconds!

Post 1 or 2 pics (and videos) in this thread for everyone to drool over.
