hi everyone...
after a long search for biofoam, depron sheet. i decided to make plane from local material. then i found this sheet and i planing to make one. after spend some hours i made the plane but unfortunately 
i am using 1400 kv motor 7x4.5 propeller 1300 mah 11.1 v battery  4 servo reciver and total wight is 798 grams. but it crash i don't understand why few pics..

1. Try using 9*5E prop.
2. Reduce the weight of your flight to atleast 550 grams

1. Specify the other details too - wingspan, length. If you have adapted from a plan, give the plan URL
2. Do you know how to fly? Find someone who does and ask him to help you.
3. This model is NOT a trainer for beginners! The wing position relative to the stab indicates a sports model
4. 1400 KV is an incomplete specification for the motor, there will be some more numbers eg 2826
