I`m nearing completion on a Seniorita build and have tested binding the wings on with rubber bands,,but don`t really like the feel,,plus I got "Thwacked" once.

In my stash of parts,I have a Bolt on conversion kit ,and was thinking about using it for my build?

If I do it,,Where is the best place to mount the hardwood hold downs and do I need to beef up the area of the wing the bolts go through?

Or is it adviseable just to leave it as is with the rubber band way?

Seems with the rubber bands there is a LOT of pressure.

I know the Seal has to be tight,,but it seems to be excessive.

Thanks

I use two 1/4" dowels thru the leading edge into the dihedral brace at the front.
Two 10-24 screws at the rear into a 1/4" real ply cross fuselage brace.

What Tall Paul is showing you there is exactly correct. And in answer to the rest of your question, yes, you will absolutely have to beef up the cavity between the upper trailing edge sheeting and the lower trailing edge sheeting. Otherwise, the first time you screw it down, you will simply pancake the two sheets together and the screws will pull through. If the wing is not yet covered, simply form two wedges of wood about two inches wide tapered exactly like the rearmost inch or so of the innermost wing rib. Glue those tapered blocks in the cavities between the upper and lower trailing edge sheeting. Now, you will be able to screw the wing down tight enough to fly without crushing the trailing edge of the wing.
