So with a helper I was able to borrow a handheld radio today to test out the radios. Again this plane surprises me as the radios were able to transmit and receive on both COM1 and COM2.
I'm feeling confident that my gamble of paying extra for the radios worked out in my favor.
I'm not sure if the GPS is working however...it boots up just fine but it cannot pick up a signal. More testing is required.
