Build new Quad + frame

After the crash on yesterday I again rebuild the frame using new 12mm aluminium square pipe with same length of 14inch or 355mm with 10x4.7 props. Built the frame and mounted the motors and electronics. Reloaded the software with 4.5 + reboard firmware.


During the test it seems to be good. Trying to achieve a hover vehicle by adjusting the EPA and trims. Most of the the part did work well. But as soon as I finished testing I switched off the Tx thinking that I unarmed the Quad. The moment I switched off the Tx the motors started to full rpm and the quad flipped and two props were broken. BAD DAY for me.


I replaced one broken prop with the new one I have and I don't have anymore of them. Trying to get them locally from Chennai or Hyderabad. But I couldn't get any pusher props anywhere in Hyd.


What to do. Its in final stage and needs to be demonstrate on Monday.

KK multicopter

Hi, I've made a Quad X copter using KK Multicopter blue board v4.5 (ofcourse I waited for 15 days to receive the board after placing the order). But mine is not going up. Its rotating on the ground. I don't what the problem is.... I've tried and tweaked as much as I can do by referring many sites. Also build 4 frames. But in vain. Its been two weeks I'm trying to make it fly.


I've used 

1450kv outrunner brushless motors

12A BEC Esc

3S 25C 2500mAh 11.1v battery

(Above all Powerhd company)


kk multicopter blue board v4.5

Futaba 6 channel T6EXA Tx

Futaba 7 Channel Rx at 72 Mhz


Everything seems to be fine. The board is getting armed and all the controls are working fine.

The weight is under 900g.


Trying to figure out what happened since 1 week.

I'll be more than happy if some one could help me on this ASAP.
