Won't that defeat the dual rx feature of the newer unit?
you'll have rx backup on all of the important stuff, and be able to get back on the gnd w/ a bat or rx failure.
Do you really want backup for smoke and NG steer ???
On the servos you don't have going through unit how do you have them hooked up to both rx's?
You don't. I have 12ch running off of rx1 and 7 off of rx2 (the backup rx)
