Okay, now we are getting somewhere. I may even put in a hardwood joiner in the center sections for more strengh. I picked up 20 sheets of 1/16X 4 X 48 today, so we are on our way.

I noticed that Sig sells the 7/8 tube and insert for $17 that is 16 inches long. I'm pretty sure it's the same one they use on the 40 size Somethin Extra. The part # for the tube and insert is SIGSH778.

Exactly what methods do you use to make the holes in the foam for the servo wires without weakening the foam in the center pieces?

By the way, about how many flights have you guys got on your Herk's so far, because I fly about 3 or 4 times a week, thats the penalty of living 7 minutes from the flying field...LOL
I'm planning on flying the Herk quite often and was a little curious on how well it holds up to a lot of flying.

I'm a little concerned about the way the plans call for mounting the engines in the nacelles. I just can't believe the fiberglass won't woller out around the screws from viabration. I'm trying to figure a different way in mounting the firewalls.
