no more scratch building....especially from biofoam.....its a useless material.... ...............everytime a make a plane..the same happen...it happened with my f22 raptor also...

Nope, biofoam is an easy to fix material that is cheap (yes, it is brittle too).  The issue is that you put a motor on such a model with no real control.  You should try to make it either a free flight one (rubberband powered) OR you should make it a full remote controlled one.

anwar sir i tested it by the method u told chucked it without any motr or anything...but after 3 meters it went up..nose at 80 degress...then fell directly of its tail

tomorrow going to buy sunpack sheet 7 feet by 4....it will cost around Rs 400

The whole idea was to do it into tall grass that would absorb the impact... looks like this was not done ?

sir couldnt fine any ground with tall grass..so tested it in my garden

hi,

i presume if the plan landed tail first that means that the plane was not nose heavy ,

But i think all gliders needs to have nose heavy to do a forward flight.

Akky don't get frustrated so easily. Everyone learns from their mistakes. So, try and build another one with proper knowledge, there are many experts in this forum who can guide and help you whenever necessary.

Good that you are not quitting. Try your luck with Coro. But don't undermine Biofoam. You see Ashta sir fixing totally ravaged Biofoam plane to fly - he fixed my Estratos whose left wing broke from middle and it flew again!!
A 80 degree climb would definitely result in a stall followed by a nose dive. Your plane was  Tail-heavy. There is this common tendency by newbie like us to make our plane Tail heavy when there is very small window of 'Angle of attack' and a slight high alpha leads to a stall.

slight nose heavy plane is better to start with. Only learning from your own mistakes would help you. If the basics are wrong, it won't be long to crash even a shiny ARF/RTF.

All the best.

goining to do it again...and put some weight on the nose

finally my plane has got a name..."DOWN 4"......todal did some decal work on the main wing

an d when i come to quiting from this hobby...its near to impossible...onece a person is in he cant get out....
