We use canopy cement to hold tails on foamies and servos in the wing and stuff like that.

Gawd Knows I've tried..as RC56 cannot be shipped to Canada. No idea of why though.
Those glues do hold but barely in my testings. Suppose on whether one is happy/can deal with a light grip or wants it to be "glued' on until forcibly removed. Don't want my canopies flying off at speed basically
Ca works well but the Fogging can be a serious problem.
Foam Safe /non fogging Ca might be good.
But I haven't personally tested that.. yet.
Plastic sources? No need to buy any as we are being Buried alive in packaging plastics and drinks bottles.
Yes we do have a lot of packaging around but I am looking for plastics that can be bent (like on a cub) without stress cracking or crazing (fogging cause by strain).

Most packaging plastics are not suitable for formed windshields.

The reason RC 56 glue works well is it has a solvent in it (probably the reason it can't be shipped to Canada). I use contact cement for my windshields cause it holds better than RC 56. I mask off the area to be glued and paint the adhesive on the plane and windshield, wait about 10 minutes and stick them together. It requires a near perfect fit and some planning cause you get one shot at putting it together.

I have been having trouble finding suitable clear plastic except from packaging which is probably PET-G. Here are some techniques that I use for installing windshields on high winger scale models:

Make a pattern from manila folder and carfully cut it to fit with some overlap at top of fuselage. Use pattern to scratch shape onto plastic with an awl, etc.

Pre-make pin holes by forcing pins through plastic in to scrap balsa for pins that will go into the fuselage top. Do the same for windshield sides.

Apply RC-56 or other similar "canopy glue" to top of fuselage where top of windshield will be glued. Canopy glue is water based and turns clear when cured. It can also be removed from plastic with damp Q-tip when fresh.

Force pins through plastic into fuselage top using needle nose pliers gripping pin near the point.

Apply glue to one side pillar and wrap plastic around and secure with pins making sure that bottom of windshield is down to boot cowl. Repeat for other side.

Run a bead of glue around bottom edge of windshield.

Let glue dry until white glue turns crystal clear. Carefully reomove pins while twisting and supporting windshield so they don't pull up windshield material. Trim excess material from fuselage top edge.

Add a strip of colored tape around bottom of windshield to cover any small gaps, etc.

Nothing like a neat new windshield installation

Or you can cut off silk pins, drill holes and use the pins to hold the windshield in place.



Finished project;
