Are you new to RC aircraft? Have you flown before? Where are you located? What type of plane are you hoping to build? Lot's of questions here...

It is very doubtful that you'll find a mold... You will have to make one. Why are you making an aircraft out of fiberglass anyway? It will be heavy! And most kits of that material will be much larger than a motor that size will be suitable for regardless... And crashing a fiberglass plane is usually a complete loss of airframe!

The foam they sell here in Canada is usually not a proper type for building aircraft either. But depron is available at the hobby store for a high cost. I ordered a bundle of Fan Fold Foam from the USA and have been happy ever since. I suggest you find an online foam dealer and have it shipped in to you.

No foam ?, why not use wood ?.

Balsa wood would be the first choice. No balsa ?, then other lightweight woods may be suitable.

No foam, no wood ?

Do you have cardboard ?, quite a few models have been built and flown successfully made from cardboard.

No cardboard ?

Any water nearby ?, fishing can be a good hobby

So you can buy fiberglass and resin, but no foam?? What country??

Unless your a experianced fiberglass worker, making a mold and a plane out of fiberglass is not so easy.
Plus all fiberglass planes are a lot heavier than foam/balsa planes.

You don't need foam to make a mold, I have used wood for the plug.

Here's a link to a pusher jet mold I made. It took a lot of time and doing it just right.

Every country must have foam It's a commonly used material for insulation in buildings and scores of other uses. Then there is balsa.

You cant buy moulds for planes, if you really do want to mould your own then you have to make a 'plug' from wood or whatever, then make your own female mould over the plug... then after all of that you can lay up the actual model inside the female mould.

This is a very skilled and time consuming process and usually only makes sense if you intend to mass produce. As noted above, for small to medium size models moulded fibreglass tends to be quite heavy.

Hey Jude, (sorry couldn't resist that one)

My humble suggestion is try your hand at building the SUPER EASY from the cheapest model airplane material....dollar store foam. Not sure if you have this material in the Seychelles though. It is made from extruded polystyrene foam sheet with paper sheathing on both sides. A sheet of 20 inches x 30 inches is a dollar at most dollar stores.

If not available there, you can order it in, but it won't be as cheap anymore.

Check out these threads:

From this model, you will learn how to build and then learn to fly it as well. This is probably the easiest RC airplane to build and fly. If you can draw straight lines, use a box cutter and spread glue, you can build this plane.

And if you are breathing, you can learn to fly it, no problemo.

After this model, sure as the sun rises in the morning, you will be addicted to RC. There are tons of plans for foam sheet airplanes in these RCGroups forums to last several lifetimes of model building and flying....for cheap.

Good luck!

If you want to see what has been made using cardboard -

Click on the Search, (near the top of the page), type, cardboard, set it to Show Threads, then click Go.

It will list any threads with the word 'cardboard' in their titles, (my search came back with 101 threads). Obviously not all will be useful, so to simplify which threads to look at, don't click on the thread title but click on the tiny 'paperclip' symbol at the end of the title. This will show just the pictures that appear in the thread.
If the pictures look interesting, then have a read of the thread.

One major point, weight is the enemy of flight, and some cardboard can be heavy, so try to keep your models as light as possible, they will fly better.

There are materials that you have not thought of that might be available. Plastic toy bats, for sale signs and house insulation foam board. I know an island is limited on what they bring in but you might have something you could use.
