Well Walkera remarks are: 1: It’s necessary to use the UP02 and UP02 adaptor for this upgrade steps.
2: This ugprade software optimized the programe,and improved the stability of the flight.
From what I read is don't waste your money on the UP02 and UP02 adaptor for this upgrade & most could tell no difference & also if you do upgrade it still says you are at version V1.0 not V1.1 so you can't even tell if you were already at the latest firmware or if there even was one.
