James Humphreys 1 Posted October 2, 2020 Share Posted October 2, 2020 Ok getting ready to glue the rudder to the fuselage balsa the instructions just say glue but don't indicate which glue, The model uses a mix of thin/thick Ca along with 5 & 60 minute epoxy. What would you recommend. Ta. Quote Link to comment Share on other sites More sharing options...
FlyinBrian Posted October 2, 2020 Share Posted October 2, 2020 Do you mean rudder or fin? If it is balsa to balsa then PVA, CA or epoxy will be fine If you mean glue rudder hinges to the fin then CA or epoxy.

Graham Davies 3 Posted October 2, 2020 Share Posted October 2, 2020 Hi James, I'm a firm believer in aliphatic resin for balsa and ply. Spread it on, push together and clamp, and wipe off the excess. Super strong and minimal excess weight. It's also not brittle like epoxy can be. If you can, clamp. It reduces the air gap and gives very strong joints.

kc Posted October 2, 2020 Share Posted October 2, 2020 Large amounts of epoxy at tail end might add weight, but would work. I would prefer to use PVA and spend some time getting the fin vertical and bracing it whilst the glue sets. I find it's much easier to glue the fin and tailplane into place after covering, which means PVA is easier to wipe the excess away. Cyano or epoxy can spoil the covering.

Piers Bowlan Posted October 2, 2020 Share Posted October 2, 2020 The problem with cyano is that it grabs instantly so there is not much time for adjustment, although with a tight wood to wood joint, is very strong. I tend to use epoxy for attaching the fin and tailplane but PVA or aliphatic (Superphatic) are very good too. Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted October 2, 2020 Share Posted October 2, 2020 If the fit is tight with no gaps, ca/pva/aliphtic or epoxy. If you have a loose fit epoxy. Quote Link to comment Share on other sites More sharing options...

Bob Cotsford Posted October 2, 2020 Share Posted October 2, 2020 It should certainly be ok on the tailplane, I use the blue bottle 'weatherproof' version for most wood to wood joints. Quote Link to comment Share on other sites More sharing options...

Agree about cyano disfiguring covering but a nice clean finish with epoxy can be had by simply wiping any excess from a joint with a kitchen towel soaked in meths. Quite possible to remove unwanted epoxy from covering even when the glue is partially set - don't leave it too long though! Quote Link to comment Share on other sites More sharing options...
