This sounds like the tail gyro is reversed or not working at all. The RX2702V has a switch to reverse the Servo response - switch 18 on this diagram.

Just a last note on the RX2702V, The TX needs to be set for 120 deg swash plate, not servo type 1 as in your settings. This is from the V450D01 V1 manual:

That's so true, I cannot even remember how the stock firmware looks
