The version 6 model is the FMS version (I think U have v3) what PW-RC is offering right now. It has flaps and the new tail wheel retract and a redesigned prop.
I'm not concerned yet with Mods, except for structural and safety. Mainlywhat batteries, chargers,etc. and other basic equipment I should get in order to fly the aircraft. Nota big deal if youdon't want to get into that, Not really your job to instruct me on the basics of electrics.
