I think I got the drawings from a Tale Spin fan-site a few years ago, and I just checked a few days ago, there are still Tale Spin fansites out there and they are current too! I didn't know there was one for X-Plane, sounds interesting, but since it is a fictional aircraft there would need to be some artistic license taken to make it fly in a game like it does in the series, or even close. And yes it clearly had some power, even without the Super Turbo that Baloo burned out to rescue Kit in the Movie (also cut and edited to be the first 4 episodes of the series), speaking of which I didn't know that Disney had a rule about never making more than 65 episodes no matter how popular it was or not, weird.
It could be cool to have a real Sea Duck made, but making an aircraft is probably hard when it's not a frame and a parachute with a Rotax in a backpack, otherwise I'd love to make my own little airplane as you've seen talked about in another thread.
That other seaplane looks cool, but I don't know the series, it looks very good though. In other flying fiction news there are the wingless things in the Last Exile anime, now there's a plane that can't be made in real life lol. Yoko Tsuno's little twin-engine jet could be cool though, Roger Leloup usually makes all places and vehicles extremely authentic, except the invented ones of course, but the little jet clearly looks like a small Eurofighter.
Back to Baloo btw, one funny autopilot wasn't it?

The drink-dispenser is cool though!
