Peter Posted October 13, 2020 Share Posted October 13, 2020 Hi peter Miller I have just started to cut out the parts to build your S-9 Chaos. I have a question regarding the wings. I see the main spars are tapered down to 1/8 from R6 to R11 which side of the spar is tapered is it the outside face or the inside face which locates on he bottom of the slots in the ribs. Many thanks Peter Mercer Quote Link to comment Share on other sites More sharing options...
barryt Posted October 15, 2020 Share Posted October 15, 2020 Hi Peter, From the designer's own thread. The spars are tapered on the inside because the ribs get narrow so you will notice that the spar slots get shallower towards the tip. If they didn't the ribs would be extremely narrow between the spar slots. So you should taper the spar before laying it down but you can taper it once pinned down but obviously before gluing on the ribs Edited By barryt on 15/10/2020 14:58:51 Quote Link to comment Share on other sites More sharing options...
Peter Posted October 16, 2020 Author Share Posted October 16, 2020 Hi barryt Many thanks for the info regarding the spars, it makes sense now. I'm looking forward to building the S-9 through the winter months. Peter Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted October 16, 2020 Share Posted October 16, 2020 Yes. You are the second person with that question. I am sorrry to make the old quote. "When all else fails...read the instructions!" If they are not in the magazine instructions. It pays to look at every related part, i.e. spars and the rib slots etc. Plans can be complicated but checking and cross checking will usually solve a conundrum Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 1, 2021 Share Posted April 1, 2021 I hope the build is going well. The other one in the club was flying yesterday. I want tp get mine back in the air but I have two models that need photographing in flight first. Quote Link to comment Share on other sites More sharing options...
