Small magnets for canopy hatches


Can anyone tell me where I can source some of the small round rear earth magnets that some parkfliers are using for holding down canopy hatches?

Thanks,
Bob

Keep it small. These magnets are powerful. If you do need more holding, put a magnet on either side instead of something like thumbtack on one side like I do with my kits.

Thanks Doug,
I can order 1/16" diameter x 1/32" or 1/8" diameter x 1/16" thick discs from http://www.wondermagnet.com/dev/magnets.html what size would you recommend?

Unfortunately there are no Radio Shack stores here in New Zealand.

if the little ones won't work for you, perhaps a small magnetic cabinet latch will suffice! (note this being for 1/4 scale aircraft...)

Thanks Doug, one further question if you don't mind. Do you have to make any allowance for the magnetic field when positioning your radio receiver?

Bob
P.S. Can you give me a idea of the cost to ship a MiniFlash kit to New Zealand ? I have got the impression that U.S. International postage rates are many times more than your domestic rates.

Good idea Roger, I wonder if you could just cut them down to size to get the right amount of magnetic grip. I'll try it out and post the results.

Kiwibob;

You might be able to order them from RS on line. GWS planes use one about 4-5 mm in dia. they work great. maybe a supplier of GWS stuff in NZ can get them.

I aways have to say something to anyone from NZ on here. My wife is a Kiwi from Invercargill. We visit almost every year. My next project is a P-51D finished in NZ livery. I got photos from the RNZAF museum in Christchurch.

See ya....

For magnets on-line, try ForceField ( http://www.wondermagnet.com/dev/magnets.html ). Look at items #47 & #48. These are good for holding your canopy, hatchs, wings (on micros), etc., and they are cheap (about 12 to 15 cents each.

Gouda, thanks for the info. The hobby shop in the next town stock most of the GWS range, I'll give them a try.

Please pass on a "kia Ora" to your wife. I hale from Hamilton in the North Island.

Your P51D will be unique in RNZAF livery. They seem to be a very popular aircraft among ezoners.

Cheers,
Bob

For some magnets a bit closer to home, try Watts Up Hobbies (NOTE: prices are per packet of 5 magnets).

I get most of the magnets I need from broken CDROM drives. There is usually a round magnet to hold the disc down, and two small square ones inside the laser unit. They are usually glued in with epoxy, but can be removed by grabbing with pliers and twisting off (don't try to soften the glue with heat - Neodym loses its magnetism at quite a low temperature!).

My latest project is a 'Sport400' plane which has magnets to hold down the wing, as well as two hatches. Hopefully it won't fall apart in flight
