You can change the modes on the transmitter.
If you take the module out you can flip a switch, you can put it in normal- or HSR mode.
If you picked the HSR mode, you can change that mode in the menu, advanced or HSR (3 of 2 way).
I thought if you're using the spectrum, you can put it in advanced.
The spectrum is just as fast as the helios in advanced with the 302 reciever, but correct me of I'm wrong.
