Any luck upgrading your repair base? I have the same problem, the Crossbill is just sitting broken right now. I somehow got the 2 platform scales needed (not sure how) but I cannot find the Rotor Balancers anywhere in my town, neighbors towns or incoming flights. I questioned GI about it and they said "don't worry you can get your parts needed for upgrade before your Crossbill breaks down" but they were wrong and did not tell me where to get these parts.i just bought my very first crossbill, started my first flight to waterfall and then it was broken. i found that i didnt upgrade my repair base so i click on it or my crossbill will be sleeping forever.
I realize that the items required for upgrading repair base have to be found in the drop of waterfall flight…
