I just received a brand new flip 1.5 with a case as a part of the electrohub kit. I have built the quad, soldered, and plugged everything in correctly. my issue is that when i turn it on and attempt to arm, nothing happens. There is no led that lights up on the board- red, blue, or otherwise. i have tested the receiver with a servo and have tested the esc's individually. I am using a DX6 also. Any input will be greatly appreciated. Thanks.
