Old junk? Drones are old junk? Do you even understand what a full scale war with Russia entails? Total annihilation of Europe for starters.
Currently that entails "large drone attacks" that kill two and injure dozens.
That's a little short of the full scale war Russia could wield in WWI and WWII.
This seems like quite the assumption.
It is generally a mistake to attempt telepathy/IP.
Russia not doing nearly as well as one might expect for an aging out core of a former superpower is not an equivilance with their target is kicking their arse.
The grind Russia is having to go through against Ukraine is an indicator of how it might fare against a full NATO (sans the US).
