Been very ill for a week now after useing it on the planking for the rockerbox covers on the spitfire :sick: :sick: :sick: :sick:
Thanks for the offer Garry i will try again today, i would like to get in touch with DEPRON FOAM the people that Tony uses as they seem to be about 30 pence a sheet cheaper than Steve Webb but cannot contact them so if anyone has a phone number for them, please


If you can find the right thread on the 3 M site there is a glue like /Cyano ( could be a modified Cyano ) which maybe a 2 part one. If you were to contact them I am sure they could advise Loctite do a rubberised instant glue However the container is rubbis. It is rigid with two push in sections on the sides which you squeeze to dispense the glue. OK all fine so far but if all the contents are not used fairly quickly the remainder thickens and won't run to the nozzle/ I complained about this and was sent a replacement bottle. And guess what. Yes exactly the same bottle I don't know if contacting will do any good but these bottles need changing to an all flexible tube like a toothpaste tube. Try 3M#s I think it was called an adhesives forum.

I hate the stuff, I only use it for furry hinges and NEVER for building.

There is nothing like a dream to create the future.

Actually I usually use the Bob Smith Industries one or BSI as it's know I get it from HK it is the odourless one comes in several size bottles I use the 2oz thick and thin, very good stuff far better than the Deluxe BUT it's $23 a throw, I had run out of it and tried some from the local DIY shop industrial strength and by god did it nail me, never again, although I still have a couple of bottles, Hmmmm I wonder if I leave the tops off in the kids rooms :evil: :evil: :evil: :evil: :evil:
I use it a lot, because I CRASH A LOT :S :)

.......because I CRASH A LOT


I haven't crashed for over three years. B)














maybe it's because I haven't flown for over three years. :blush: :( :(

I have, once, but it was a structural failure in flight. (probably too many 'G's!) I've had a couple of near-misses when a servo failed in flight.
I HATE those furry hinges, always remove and discard them, and use proper nylon ones with a steel pin in the pivot - and I pin them in!
I've seen too many control surfaces fall off, when the builder has used those furry things, and been a bit mean with the cyano, (i.e. ARTF) so the hairs have stuck, but the hinge itself hasn't.
And - of course - cyano will not stick to cyano, so you can't re-glue them!

if you are calm and collected when all about you are going berserk - you've missed something important!
