Hi Guys,
I've got yet another GP Spacewalker question

.
What is the right way to install the large control horns for the Spacewalker ailerons? The ailerons have a wooden control horn mount on one side (the bottom), but just monokote on the other (top). I've got these DuBro control horns:

It seems to me that tightening the bolst will just pull through the monokote.
How did you other Spacewalker owners get around this? Any pictures that will help?
Thanks,
Carl
