Belnder is free, open source modeling, texturing, and animating software. It even has a game engine, so you can enjoy piloting your creations (with a little more practice).
You can download Blender here:
http://www.blender.org/And they have a quite a good forum here:
http://blenderartists.org/forum/index.phpThere are a few trolls on the forum sadly, but mostly the regulars are OK and there are one or two really helpful people there.
However, the help forums are great, and there are a few dedicated helpers who always try to answer your questions (if it hasn't been asked before). You can search the site to find answers to common frequently asked questions, so you may get no response if you post a request for help without searching first.
