RE: PA mini Katana vs ExtremeFlight Extra
ryguy mentionned another very interesting entry in between the ef extra and the pa katana; the BME yak in terms of size and weight it's right in between the katana and the extra, (to add to your dilema) and it looks extremely realistic, much like the extra. Any 3 of those would be excellent, but as ryguy also mentionned the auw of each must be taken into consideration to select an appropriate power system, if you allready have your power system you might want to choose accordingly.
