Credit cards can be cut with scissors while the CD needed the Dremel and a small hacksaw.
Wow, those look better than store bought ones.

Fiberglass circuit boards also make great "high end" control horns. Find a good one (some are Bakelite and are brittle, others are too thin) with the right thickness, cut it out, drill it, and sand off any offending copper paths.

Fiberglass drywall tape makes excellent reinforcement for thin foam stress points. Just stick it and rub a bit of glue.

Dremel or just scissors . The thin plastic film coating will come off , but I've never had one fail from being brittle .

I got tired of digging thru the drawer for the smaller, leftover size of piano wire or cf rod for small projects. Wood base with replaceable foam.....had it organized with tall in the back to short up front, but that only lasted a week or so.

I've tried the hot glue hinges, the floppy disc hinges, even the store bought fiber ca hinge. But for simple and easy, the packing tape hinge is the way to go......plus I get my packing tape for free.....don't tell my boss

Plastic tubes, shave cream caps, pill bottles, etc. make good hole cutters. Just file and sand the edges sharp, and twist and turn them into the foam till the hole is made.

Bread-bag clips work great for control horns and guides and wood scraps can be handy too.

Japanese bamboo blinds make vey good small pushrods among other things. A lifetime supply from a 4 by 4 ft. blind. They are a little over 2 mm or 3/32 in.
These veneer strips and sheet from Home Depot have glue already on one side and need only be ironed onto foam for strength/ bracing.

I like the bread clip idea, but the wood and magnets have me a little lost.??

for easy and superlight control surface activation , we use Pull-pull cables (string) and no need for control horns , just a short piece of a bamboo skewer does it . Works remarkably well, weighs almost nothing ... cost almost nothing too ..

I happened to have some "Left over from Kite building" Kevlar thread.
NO stretch and Super great for Pull Pull set ups.

Been using PP on a 5 yr old FalClone 60 , No problems !
Same on an Old Timer Buccaneer.
And an over sized 3D plane - The Red Trim.

For Pull Pull on Heavier Gliders I use Berkley Leader line, stranded and plastic coated.

Joystick trans made from an old computer joystick and a cheap HK Orange transmitter.
Foam pockets to keep batts warm for winter flying, made from the thin clear foam that electronics comes packed in.
