A nice program called Anim8or 0.9c

This is a small freeware program....small cause it's just about 700kb in size....and you don't need to install it...just click twice in the .exe and the program runs....
You can do many type of objects including airplanes....you can create animations, bones cameras and stuff....you can also render your objects...and work in full shade mode....the best yet is that can export your models to .3ds...It's a great gem to check out.....
One thing you must pay attention is that when you put the mouse arrow in a command Icon the name or function of that Icon appears at the bottom left of the screen....like microstation and stuff....

And some screenshots below...
