I am using a Spektrum DX9 and a Naza V2 on an F450. On my little 250 racer I arm the Naze with a two-position switch, and we find we prefer this to the sticks-in arming on the Naza. Is it possible to set up the Naza for arming this way?

Hi, buddy.

What do mean by "250 racer" and "sticks-in" ?

Still don't get it. Sorry~

Sorry  Naza can only trigger the motor by CSC

I  don't know the software of the spek, but it's is possible if you can to override the command to simulate the CSC. With futaba and the flight mode maybe is possible.
For the OpenTX user it's very simple, try to watch this video:
