Sure some use there own stock transmitter with hookups to work on the FMS Simulator, I elected to get the control box at around $25 so not to tie up or use the battery transmitter etc, but your choice, not much more investment you can get the controller...but here's one of likely many threads on this:

Good luck on the Blade 400, if your not aware check the Radd method for taming these highly responsive CPS, perhaps the best self instructions available, really helped me avoid some of the crash progression ...Its the Best ..<>..

Radd, know it, breath it, memorize it, it works !! Battery One !!!!
