Talking with some of the guys at the flying field this morning, it seems the FT guys are lagging at getting the plans available online. I have the Mini Zero, and one of the guys commented I should have traced out the parts before I built it. When I commented the plans should be online, they said they weren't there yet.
Not sure if there is some other issue holding them back, but it's not just the Corsair.
So I have printed out the Master Series plans at 75% size and built a smaller Corsair from DTFB. Some modifications to the power pod during the build to accommodate the battery but overall the same build and a smaller Corsair. Flies as good as the full size Master Series Corsair.
