im a react user......
any other option beside original transceiver
maybe spectrum 2.4 or futaba 2.4 or sanwa 2.4 ?

i've read a couple of posts that say spektrum rec will work but latency is not as low. something about operating in low res versus high. ???

You can use the Spekrum DSM NOT DSM2 receivers.

I almost forgot...make sure you visit the Nomadio site and download their latest and final update then transfer to your radio. Did some research and found that you can use any Spektrum rx as long as it is DSM...won't work with any DSM2 rxs...latency is at about .11, Hope this helps...
