Drag brake is fully adjustable when SSL is enabled. There are 4 settings that can't be accessed via the radio that require manual setup; voltage cutoff, temp shutdown, reverse mode, and blinky mode. Basically once set you will never touch them unless you swap between blinky/boost mode.

Then there is an SSL blinky mode. Which means that the other 8 adjustments (8 when boost is enabled, 5 when it's not enabled) can't be accessed from the radio and it must be setup via the button on the switch like a boring old speedo.

But with SSL enabled you can adjust drag brake, brake feel, throttle feel, yadda yadda from the radio. You can even assign the various levers, trim switches etc to the AUX functions. And even more insano since race mode has to be enabled you could have multiple set-ups that can be quickly thumbed through via the Rmode button.

So, thats a long way of saying it can be a simple speedo with double blinky which means no boost and no adjustment from the radio to a full ballz out crazy adjusting multiple parameters with a press of a button tech geek out.

It's nutty that the way the current ROAR approval is written that everyone that bought the bargain SV0/472 combo can't use the receiver even though there are provisions for a "blinky" adjustment mode.
