Feedback on circuit board for custom Flight Controller

I removed the R1 and R5 pin (between TX/RX CP and uC) and now it works at least!!

Ah, but there is a larger crystal on it? Maybe that is the one going to the other MCU onboard that I believe is the on board (programmer)?

I can at least recieve Serial prints! My LED doesnt blink in the blink sketch, but I get something at least :smiley:
