What 's the material that you have used for the making of fuselage.From picture it seems like Sun-board

Also let us know that whether you have used a normal thermocole sheet or Hd sheet for wings.

kplkum

Yes its sun board.and normal thermocouples.

Nice build ..
How much weight without electronics ?
How you shape wings? Looks like under curved .
Nice one.

May be 500gm to 650gm. Yes wings are under curved.

@kplkum: Your build seems to be good. A small suggestion, please check your trailing edges. Also, which airfoil is this? Did you used hot wire cutter for it?

kplkum

Just simple cutter..that's plastic cardboard.

You need to work on your wing for a better airfoil. Kindly make a hot wire cutter and using a good template slice out your wing.

Well... the entire wing profile may need to be looked into for being aerodynamic.  The model may fly... but with a very high aerodynamic drag.... i.e. high penalty on overall performance.  It could be a roll to one side, or a wing drop or a tip pitch up...... or plain extra drag.  Also look into your aileron thickness... they need to flush in properly with the wing aerofoil.
Happy Building
Well I been into aeromodelling since I was in School....  and then been in the air for over 30 years.  Now looking to be back into aeromodelling full time...

Ready for first flight. .mmm

@kplkum
You have marked your video 'private'. So no one can see!

essaargee

Youtube says that the video is 'private'  :) . So, no chance to see the video. ;D  That apart, What did you expect ???? It seems that you have made no efforts to take up the suggestions from those seniors who were kind enough to see your thread and suggest some changes, like Shobhit17  :salute:. The airfoil and the alignment of the control surfaces were sadly mistuned / misaligned  :banghead:. You have seen the result...  :( Never mind man, there is no end to the learning curve and it is never too late to start, learn and earn by experiences . Keep forging ahead  {:)} {:)} . Good luck. 

utkarshg13

@kplkum : everyone warned you for your airfoil and control surfaces. Not seen your video but could figure out what would have happened..
:iagree: with essaargee: " there is no end to the learning curve and it is never too late to start, learn and earn by experiences . Keep forging ahead"

Plane flys for one minute and after by mistake it fells down. Plane was frying perfectly.
