#26 Model airplane build clinic... Astro Hog.. It flew
I'm building an old Sig Astro Hog kit. The kit I'm using is from 1983.
Almost ready to fly
More first flight pictures at last post
This is a newer version of the original Berkeley kit. The construction is a little more complicated than a nice laser cut kit, but still a fun build.
Step one. Take an inventory of the supplied parts. All I was missing was the decal.
Start building the parts to make the plane. The ribs need plywood doubler's added, spars have to be reinforced and the wing tips have to be laminated.
I used a piece of left over spar to stack the ribs and sand them so they are all the same. Die cut ribs always have variations between ribs. A little sanding and they're nice and straight.
Wing tip parts
Spar pinned down and ribs glued to bottom spar. Hole in ribs were added to allow servo wire to pass through. I'll be using two servos instead of the single servo with torque rods.
I added the trailing edge sheet for the top and the wingtip.
The plans called for bending the 1/4 inch square spar to go over the end rib and attach to the wing tip. To relieve stress, I used a razor saw and made a small cut on the bottom of the spar at the last rib.
The spar bent easily and I've since sanded the tip and added the gear blocks. Some sheeting and I'll start the second wing half.
Second half same as the first.
