#75
Pics no. 9-12
As there is a page break here, you need to see post no 73, 74 and this together to make sense of them.

These 12 shots represent perhaps 1 second in real time.

Since pic nos 9-12 don't make any sense without reference to pic nos 1-4 and 5-8 (which are on the previous page), i am repeating posts 73,74 and 75 here, so that they are all on the same page.

Pics 1-12 need to be seen in sequence...

Will ask Anwar sir how to solve this problem of how to keep connected posts on a single page.

Hi everyone,
About 3 weeks back INDORE TLG1 just exploded on hitting the ground in a full speed dive.
Since then repaired/glassed front fuselage.
Weight has gone up from 44 to 51gms. Loading has gone up from 3.1 oz/sqft to 3.6!
This 15% increase has reduced still air time from 35secs to 25 secs.

Chuck glider enthusiasts may be interested to see the attitude of the model in the launch/climb phase.
Here are 12 stop action grabs from this Sunday's (20/4) video (courtesy our videographer Aunt)
Pl see them in sequence.

Good Stuff. Seeing this - I have also made a TLG and started flying it.

Am pleased to report that all the hype is true - TLGs are superior to conventional chuck gliders.

It is also a great crowd puller .

Been experimenting with reducing nose weight.
After a certain point, the CG has been moved back so much, it is behind the neutral point.
The static margin becomes negative,
And the result is SPLAT!
(Will try to repair before next weekend...)

Iyer sir

you need to post youtube videos a shown in the image below, basically if you notice url within Square brackets in the beginning and slash url at the end isn't required and you need to lose http or https, instead use www. In fact correct to post'em is also simpler and easier

easier way is keep posting and i keep cleaning them up, then that will entail the delay of me noticing it


Thank you for sharing the tip on how to post videos with in-place view instead of just the links.

Just posted a few videos in the following new thread: http://www.rcindia.org/cars/veels-on-5er-hobbies-video-series-for-rc-car-hobbyists/msg203925/#msg203925

Hi everyone.
Back on this thread after nearly nine months.

After the SPLAT last June, repaired her, but she didn't fly like earlier.
So decided to replace the fuselage body...

K K Iyer

Repaired.
Ply fuselage sides for more strength, and lead covered with hot glue for nose weight.
But she now weighs 50gms instead of 44gms original.
No HLG can tolerate 15% weight gain.

For those who are interested in wing loading data, she is now at 3.5oz/sqft.
HLG/TLGs of this size should be in 2oz/sqft range, ie about 30gms for this model of 0.5 sqft area.

Since I used the lightest available balsa, I fear my Make in India efforts are simply not up to international standards...


K K Iyer

CG still over 50% back from LE.
Note fin is not touching down.
