Talking about holding foam... i got this 6-pack of glass jars from my local bits-&-bobs store.. nice parrallel sides. Filled with sand they make nice hold-em squares while waiting for glue to dry...

Save those foam food trays , you can cut them into flat sections and glue them together to make a plane ... here’s a pic if the latest Foam-EZ , canard , made from grocery store foam chicken trays ... FREE .. Colored tape (Fast-pac) makes it pretty ....

I save all the old vacuum formed packaging from what ever I do buy.
Just used some from a couple 3 packs of CA tubes of glue to make servo protectors.
Used em for making air scoops, covers for esc's to direct airflow and water protection.

And don't forget the plastic Dixie cups, they make great engine cowls.

Everytime I pick up something I see in the parking lots, my wife asks me what part of the plane is that trash going be for.

Old lead wheel weights or battery cable....cg balance
Broken driveway fiberglass marker.....spar
Stiff wires......landing gear, control rods
Used zip ties....cut off the unused end,still usable
Plastic caps....because Im always losing one, and this one might fit
Metal bolt washers.....flat cg balance, cut slit and insert
And many more that I cant think of at the moment

Here's a good tool for your electric screwdriver.
Take your worn out Dremel and cut about 1 inch off the drive end. File the hexagon flats to fit in your screwdriver. Doesn't take that long as it's mild steel and easy to file. Also the outside diameter is the right size for your driver. Screw the drill chuck on the threaded end and your good to go.
It's handy for drilling wood and plastic where you don't want or need the high speed. I use it much more than my regular drill.

Fly, great idea for the screwdriver chuck! I wonder if I could turn down and thread a long disposable screwdriver hex bit? (Might be too hard, eh?) I have two of the little screw drivers like you show; harbor freight 4.5v type. When they wouldn't hold a charge anymore, I swapped in a 1 s lipo (850mah split in half) that worked OK, but I found I could squeeze a complete 2s 850 may lipo in the handle after a little trimming. I soldered motor wires and ran the balance wire out the back for charging. Running the little motors at 8 volts hasn't damaged them, and I get several weeks of use from packs that won't fly a plane anymore.

One of the easiest ways to change your thrust angles on smaller electric motors is to break off the end of an Exacto knife blade . Loosen the screw and slide it behind the motor mount. So much easier than washers and you don't have to take the screw out.
I also use plastic spoons for air scoops.
