instead i decided to make one..
gone through all the website as possible.. didnt find any build log..
finaly decided to build my own so that i can make a build log later..
selected kinkade's slowhawk as my model and started to download as many pictures of that.. using my ideas and stuffs available locally and started my build few monts back..
the main problem was the gear assembly.. and searching for proper gears.. i dont want to spent more by getting gears online..
got some help from kazuhiko Kakuta(rcgroups) and models previously submitted in RCIndia as well..
now the wing action is almost good in my calculation getting enough trust..
see my video of wings test... and please give your valuable suggestions...
Bravo Arun , Good job !
I suppose it will fly as it is, just find some flying field with taller grass for minimizing ground strikes impact . Also some play with center of gravity will be probably necessary too.
If it doesn't fly then increase the flapping angle.Your one look like 30 degree ,most common is between 45-60 degree .This will lower the necessary flapping frequency as well.
Also if it is not stable enough make flapping angle asymmetric regarding the horizontal neutral line or for example if your total flapping angle is 50 degree make it flap 40 degree over that imaginary horizontal line and 10 degree down.
I wish you success and Happy New Year !
