Nope, but I've built two of their 749s, Which I happen to prefer anyways. And I've built two of their DC-6Bs which I highly reccomend. Plus all kinds of other Heller/Airfix stuff.
To the point however, I love the kits. The only fit issues on the 749 is getting the five pieces of wing together smoothly. I glued the fuses together, then in a massive assembly the middle underside plus both tops, bonded securely to the fuse roots. Then I added the underside end panels last, and had to deal a little with that seam, but it's underneath so what the hay. The landing gear is nice and sturdy. I wouldn't waste time on the cockpit as there's no way to see anything through that tiny windscreen. Must have been kind of weird to fly.
I've got the L-1049 reissue in an Airfix box, in the stash. it's destiny is to be an EC-121.
