I intend to incorporate MOD 77 but the MOD leaflet gives no advice on how to incorporate when the rudder is the hollow NG type. I asked Europa and received the following response. Has anyone else encountered the same problem that could also offer advice? many thanks

I remember the shop floor coming to see me on this issue when building the Demo aircraft last year and although it is not in the Build Manuals yet this is what we did:
They had to shape a block of blue foam which was bonded into the rudder leading edge in order to provide a layup surface for the cloth and bracket installation - easy, well not really - it is a bit awkward to do.
I remember they had to be careful in shaping the block so that it could be slid into the rudder leading edge and positioned so that it overlapped the cut-out by 50mm i.e. 25mm at each end. The block can be bonded in position with Redux 420 and cotton flock OR just Flox. As stated above, the foam is not used in a structural capacity but just as a surface to lay up on.
Also, you will need to keep checking the fit of the bracket as you go along as I seem to remember the cut-out had to be adjusted slightly in order for it to fit in its correct position - something about variations in the size of these welded brackets maybe. Please bear this in mind and I would appreciate you letting us know how it works out in your case. |
Many thanks
Alan
