After reading all the comments about converting a $10.00 foam glider to electric, it does not appear to be a good idea for someone just getting into the hobby. I need something that's not to costly. I am 71 years old and on fixed income.

Yes, the glider conversion can be a bit tricky for beginners. Choosing electronics, finding the CG (center of gravity) and making control surfaces can all combine to have less than favorable results for the maiden flight.
If you are looking to get into this amazing hobby, I would try first to find a Flying club local to your area. They will assist you with where to start, and tips, etc.
Thankfully, this hobby can be done very inexpensively. the average foam board airplane is less than 5 dollars. Most of us use Dollar Tree Foam board, which is super lightweight and of course, only a dollar per sheet. this foam can obviously be found at Dollar Tree stores in the USA and can be ordered online from flitetest or other companies.
If you are interested, my first reccomendation would be to build a chuck glider. the FT Tiny Trainer is a great option, as it can be motorized down the road. For this build, you would need 3 sheets of foam, as well as the tiled plans on FT’s website:

Building this plane would require some hot glue and maybe a few BBQ skewers and rubber bands but likely nothing you couldn’t find around the house.
Building the plane as a glider would help you determine if you are interested and you would like to continue and put more $ into it. If you aren’t, you are only out of 3$.
If you choose to take the next step and put electronics inside, the biggest expense will be the radio. You can find decent ones used for well within 30 bucks, but getting into the lower end of computerized transmitters will take you near 200 dollars. All the other electronics can be bought easily for under 100$.
Hope this helps!
