KK has valid points. Looking at the Slo Mo footage few take away on flaws-
-the aircraft is starving for power,too heavy
-off course flying skills
-structure and design count major one

@K K Iyer:
not at all sir...
In fact its great to know I'm getting to learn so much regarding building planes....
Reading about is different and of course building and flying requires a different skill as well....

I am working on another plane...
these points help me incorporate changes to my model at the same time...
Sorry if any of my comments did offend you, it was not at all my intention...

its just that I have lot of excitement that's why I wish to explain more and more about how I went around designing it...

@iwincar:
Agree with you....
yes the craft was starving for power, though really couldn't understand why...
Do you think is the motor underpowered for the weight or is it a design issue...

@k k Iyer:
also the plane seems brilliant...
do you have the video of the flight...?

Archer: in fact your design is quite different reminds me like the one saw with sketches of Leonardo Vinci (certainly not comparing you) but visual feel to it quite radical ...
Since u r an techi there is distinct ratio to weight:dimension: motor:battery: prop size

Da vinci...
whoa didn't know that..
do you have a link or any other info regarding that...?
would love to see it...
(I hope he did not patent his design... )

would agree to you on your second statement...

Wow Great Plane Sir

Chk da Vinci flying machine designs

yup the design does seem radical guess he tried his best to mimic the birds in his ornithopter design....
I really wonder what if it flew....?

Not brilliant. Just nice. Here's a 35sec clip...

nice flight and it is brilliant...

Hope I fly my next plane properly...
also manage to get a little more air time....

I know adding landing gear would mean extra weight but it will help save the prop, most of the time

Good job on the overall plane very innovative :-)

Thanks Hellyflyer....
and will definitely take your advice....

I should have added them in the first place....

The whole thread is a breath of fresh air

Archer, this is a very interesting and commendable effort. As an engineer myself (IIT-B, Class of '79) I appreciate and commend the thought and effort you have put into the very original and well planned design and build.

After going through the comments by others, I can assure you they have not really understood what you are doing here. Therefore go on tinkering; you are almost there!

All the best 

thanks a lot sir...

I'll do my best and will continue to experiment.....
