Hi Guys,
I have always hated putting the L/E sheeting on the wings, some planes are worse than others. On my recent build of a 1/4 Fokker DRI I tried something new(to me anyways). I lightly wetted the outside of the sheeting with Windex and let it set for a few minutes then I attached the sheeting along the top spar with Med CA. I let this fully dry then lifted the sheeting and applied Med CA along the top of the ribs and the L/E. I then used a heavy walled 1-1/2" metal pipe(longer then the panel)and gently but firmly rolled the L/E sheeting down from the spar to the L/E. Once the sheeting was down on the L/E I shot accelerator along the joint at the L/E.
This resulted in a pefrectly smooth sheeting that was well bonded to all the ribs and the L/E. If your wing does not have spar webs in place at this point you can always go back and wick thin CA along the joints.
Later!!
