Cheap 3D printed H quadcopter

Dropping the quadcopter from different heights to see if it is breaking :)

Hi guys , this is a cheap quadcopter i have built to test my obstacle avoidance system. Since there is going to be a lot of  crashing i wanted it to be strong so i made a model in 3D and gave it for printing 

 and the outcome was

i installed 

4x EMAX CF2805 2850Kv motors

4x HK SS 15-18A ESC

KK2.0 flight controller

3S 11.1v 1000mAh battery

5030 propellers

and flysky radio

 Outcome :

The frame is strong even 7mm thickness and it can withstand crash of any magnitude.

i would like to thank 3Dprintronics.com for printing the frame.
