Daniel,
First of all welcome to RC Universe! Now, $33 is pretty cheap for a plane. It can also be a very expensive piece of junk. I'm leaning toward the piece of junk. For $33, you will get a plane that barely flies, and no way in heck is going to fly for 20 minutes. More like 2-3 minutes with the stock (crappy) battery. You will end up frustrated and turn your back on a wonderful and rewarding hobby.

Tight budgets can be a problem, but have you checked around the local club where you live? Many people in this hobby are generous souls, and willing to help out the new comers with their training, AND their equipment. If you lived closer, I'd have you set up with a proper 40 size glow plane, engine and radio to use until you could afford your own.

Stay away from these cheapies, and save up for something decent. Good luck!
