Cyano will stick pretty much anything, might not be the best choice though, will the parts get handled in use, they dummy exhausts or similar ?

canopy clue works the best formula 560 dries clear and has a bit of flex in it , so takes little knocks better

They already painted Martin or is there work left after gluing ? Been impressed with the Brown Gorilla glue myself, it does expand though, canopy glue I've used that's good, neater than epoxy for me.

I fill the parts, if they are hollow, with a balsa plug, this is where your glue choice matters, ( I use CA..no good for you, but perhaps the gorilla glue would be good.) then tape fine grit sandpaper to the place they need to fit and rub them over the surface, you now have two parts with identical surfaces, and a nice fat area to glue. Wood glue will now give you a very good bond.

hello martin, consider aquarium grade clear silicone...small tube around about £5.00 great for what you want...strong as out.

Try using Modified Acrylate 2 pack adhesive . It sets very quickly and etches into most plastics and is very strong . Its quite thick so has good gap filling qualities .Ive only seen it on the net but you may find it in the UK

I always use Deluxe RC Modellers glue for canopies and other plastic bits, works great, sets clear.

Another vote here for canopy glue.

I just put the plastic wheel well inserts into my Kyosho Mustang using UHU-POR as a contact adhesive, which I find works well for fixing plastic parts to foam or to balsa. I wouldn't hesitate to use RC-56 if I was going to leave it taped into place for 24 hours in accordance with the directions.

If you can't use medium cyano, then I would suggest varnishing the wood and using either fish tank silicon or decent double sided tape.

... no need for extravagant solutions here, Martin.

If the plastic parts are hollow, Dwain's tip is a strong one.

If they are 'plain', just use a drop of Deluxe Superphatic as it will achieve a perfect solid bond between the plastic/wood parts without nasty odours or fumes... yes

Cheers

I use canopy glue. Needs to be held securely and given plenty time to set, at least 24hrs or longer.

Watch out for silicon if you are painting anything after gluing it together as paint generally doesn't like silicon. I've used brown Gorilla and canopy glue in the past, both take paint ok.
