Hi -
I have seen references to the spacers but as far as I can tell, none came in the kit. I believe that my kit came with the wood package for the Nuance as the aileron servo mounts looked a little different from those shown in the manual and the mount for the belt drive installation was not included. I am using an AXI, so that was not a concern.
Looking at the stabs, given that the root rib is balsa, I was not sure that a spacer would do much good unless if is glued onto the balsa and allowed to rub against the fuse. Is that what you did? I looked for photos but did not see any. An alternative would be to glue a 1/32 piece of ply covered in ultracote at the base of the stab to act as a spacer.
Thanks,
Teo
