It seems to have the RX2623V-D. That would be based on the DEVO protocol. So yes, they will be compatible.
But DeviationTX would also be compatible with the older WK (and more) protocols, e.g Spektrum DSMx for Blade 200SRX (flybarless fixed pitch with SAFE system).
Wow, flybarless fixed-pitch. Never flown that. Will probably will much better than a Blade 120SR
