Large Model Association Forum

Its been suggested by Jan, at Adfa models, that i use magnets to secure the canopy on my fournier built by Jonesy from his kit, (and very pretty it is too )
Rare earth ones have been suggested, now, this canopy is over a foot long, does anyone know where to get these things, and are they safe? i intend to use 2 leading edge dowels, and place the magnets along the canopy rear, they have to be small, but very very powerfull, anyone any ideas where to get them, and what type? will they affect the radio?
(spekky reciever,)

Allan,try these I have used them www.magnetexpert.co.uk

Allan,I have found the label that was on the box for the magnets I used on my Mitsubishi.
part no.F330NA [NORTH]
SIZE--20X6X1.5MM
QUANTITY--10
MATERIAL-N42 NdFeB +NiCuNi
I will check to see if I have any left.[Long shot]but you never know. Sorry Allan I have looked at my canopy but I used all ten.
I hope the above info will help you.Brian.

10!!!!!!!!!!!!! I thought i would be using a couple thanks Brian, much apreciated one thing, with 10 magnets, how do you get the canopy off? or shall i start looking for a scale crowbar

Allan,I actually used 16 because the Mitsubishi has two separate canopies,and there is one on each corner making 8x2 =16 because you have one magnet fixed to the removable canopy,and one fixed to the frame of opposite polarity.
In your case you will need 4,because you have dowels at the front and only require magnets at the rear.You could get away using just 2 magnets if you use a pieces of steel instead of the other two,but the holding power will not be as great.
ps.I think a pack of 10 cost about £7.

Loads to choose from on ebay, you can choose the size and thickness you want. I got a pack of these for £2.90 free p&p: Neodymium Disc Magnets 2mm dia. x 1mm thick (Pk of 50).

is 2mm eough? what diam and thickness have you guys used?

hi Alan i have a pack of magnets i use on canopies. they are about 5mm dia and 12mm long, would you like me to post yew some?

Thanks Paul, just ordered some 10mm diam, 5mm thick, i am wondering if i have chosen too big, come on guys, where are you?

And, after Brian told me he had put the sizes in his post i have cancelled the HUGE ones i ordered, and re ordered the same as Brian had put in his reply to me, shame i didnt bloody look in the first place, thanks guys, and thanks to Paul for the offer

I use the small 2mm x 1mm ones to hold small switch & charge point hatches shut (1 in each corner of the un-hinged side, plus 2 more in a ply plate in the fuz, so 4 in total).......for a large canopy, I'd be looking at something 6-10mm diameter.

Cheers Phil, i have ordered 20x6x1.5mm, i have always been a screw person, but Jan suggested i try these things, the jurys out

I've used four 2mm x1mm on my 1/4 scale Me109 canopy, ideal for keeping it closed. They will pull the canopy closed from about an inch away.

blummy, how powerfull are these nimoduim nimoe little magnets
