MattyB Posted November 10, 2020 Share Posted November 10, 2020 Posted by Stephen Jones on 09/11/2020 17:04:49: Hi, do you mean the April 2015 RCM&E here With the cartoon Cutlass And the KFm aerofoil here KFm-4 is my favourite - it's got very benign handling and is easy to build as you can score and fold the top and bottom pieces around the LE, then glue it to the centre layer on both sides. Whichever one you choose I'd recommend armouring the LE with Duck tape or similar (or fit wooden LEs if not using the fold around method).
