Have you checked the TX to see if you have any mixes enabled??

Turn off ALL mixes. Inhibit them (INH)... especially the REVO feature!

You can fly with absolutely NO mixes set in the TX.

It is VERY unlikely the RX is the problem. The RX 'listens' to what the TX has to say and does what it told via TX programming... mixes and all.

Is the TX you have a heli or an airplane version radio??? If you're using the Airplane version, some mixes are ALREADY enabled as default, so you'll have to inhibit them... Not realizing these mixes are 'ON' will cause you to pull your hair out in frustration.

You didn't list which servos are plugged into which port# on the RX.
