steve watkin Posted February 4, 2012 Share Posted February 4, 2012 First ARF build as a returnee after a 5 year lay off.When it comes to joining the wing halves together on the high wing Calmato the instructions suggest that all you have to do is push the substantial plywood dihedral brace into each half and tape the two together over the centre section ! Seems a little risky to me but I appreciate that things change over the years....................will this work or should I really be using epoxy?

Alan Cantwell Posted February 4, 2012 Share Posted February 4, 2012 only if there is room for the epoxy, if the brace is a good fit, then use it as designed, on the YT models, we get asked lots of times if tey can be 2 piece, the answers always the same, only if you make a new set of joiners that actually fit, they are made with enough room for epoxy to get in Quote Link to comment Share on other sites More sharing options...
steve watkin Posted February 4, 2012 Author Share Posted February 4, 2012 The joiner (singular) is a good tight push fit so I was really asking if I need to epoxy the root ribs together. But upon thinking about it, that's not going to add any real strength is it?So if I'm not going to glue them, what tape is good? Quote Link to comment Share on other sites More sharing options...
Alan Cantwell Posted February 4, 2012 Share Posted February 4, 2012 i keep glider wings on 4metre glass scale gliders wtih no more than a piece of white electrical tape top and bottom, i take it with this model that its a top winger, with the wings banded or bolted on?

steve watkin Posted February 5, 2012 Author Share Posted February 5, 2012 Bolted with two bolts at the back and two dowels at the front, so the wings are well located when fitted.Suppose I'm coming to the conclusion that Kyosho have got it right!!

Ben B Posted February 5, 2012 Share Posted February 5, 2012 I'd epoxy it. On my Calmato (sports 40) it said you don't need glue but in the UK instructions said the epoxying of the wings was recommended strongly. Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted February 6, 2012 Share Posted February 6, 2012 Steve, We have a Calmato TR (flies superbly BTW), and we opted to epoxy the wing halves together - including liberally coating the joiner itself). No real justification, bt old habits die hard! tim Quote Link to comment Share on other sites More sharing options...
Alan Cantwell Posted February 6, 2012 Share Posted February 6, 2012 if you decide to glue it, i must stress that there must be room for the actual glue, if the spar is a dead fit in the slot, then there will be no glue gluing just the wing halves together seems just a balsa to balsa join, waste of time---and glue good strong spar, good fit in the spar box, dowels up front, 2 bolts down back, what are you going to do with the thing? 3d flying? its a trainer, Quote Link to comment Share on other sites More sharing options...
steve watkin Posted February 6, 2012 Author Share Posted February 6, 2012 Posted by Alan 4 on 06/02/2012 16:53:08:, what are you going to do with the thing? 3d flying? its a trainer, What do you think puts the most stress on a wing centre joint, an experienced pilot doing low airspeed 3D or a beginner not realising that he is loosing height and gaining air speed and then suddenly pulling full up as the ground comes into view? Well it is a "trainer" !! Quote Link to comment Share on other sites More sharing options...
steve watkin Posted February 25, 2012 Author Share Posted February 25, 2012 First two flights today with NO glue. It's still in one bit! Edited By steve watkin on 25/02/2012 18:11:03 Quote Link to comment Share on other sites More sharing options...
