madyottie 82 Posted May 8, 2020 Share Posted May 8, 2020 I've built a new rudder blade for the Noelex. It's a kick up, rather than dagger type. Just wondering what is best for packing around the cheeks, so it can still swing up/down easily, yet doesn't flop around. Discs around 350mm diameter would be ideal, to prevent the control lines from slipping down the sides and getting stuck. I have previously used stiff mylar, PVC and similar things, happy to use same again but no idea where to find it these days. What would people recommend, and where would I get it? Also, does anyone know where to get thin (10mm ish) extruded polystyrene? I want to mess about with some shapes. Quote Link to post Share on other sites
splat 55 Posted May 8, 2020 Share Posted May 8, 2020 do you have an adjustable clamp type arrangement to prevent lateral spreading? Quote Link to post Share on other sites
madyottie 82 Posted May 8, 2020 Author Share Posted May 8, 2020 Yes, used the ridiculously over built existing rudder stock. Blade ended up being a bit thinner by design than the old one, hence requiring a little packing. Only 2-3mm total. Top end is majorly strong, so I can add thickness for experiments. Will make new stock one day, but not for this winter. Quote Link to post Share on other sites
