I remember being offered a free plane back in the 70s. Somewhere up north, and it needed recovering (maybe a T-craft?). Wasn't interested. My dad had a few offers for free planes - pay back hangar or tie down fees, pay annual, pay "get it flying" and ferry fees. He never was interested either.
As far as this guy, it seems the only thing he knows is that he wants plenty of viewers (yeah, I'll watch a few more).
For myself, my last "big" resurrection was a (free) 1983 Yamaha 1200 that had been sitting for 16 years. I started with: "Will it turn over?" jump started (yes - and sounded like it had compression). Does it have spark? (yes). Dump a little gas down the intake - yes, it ran. From there I started investing money. Battery, gas tank (original rusted thhrough), hydraulics (brakes - clutch), carb removal, cleaning. Got it drivable and spent a little more. Drove it a few hundred miles and the gremlins of storage started showing up as the multiple bells and whistles started appearing (cruise, air ride, etc). I sold it for what I had put into it. Maybe I should have made a Youtube video... Dennis
