I kind-a just threw this together:

1) Old Black and Decker workmate

2) Scrap poplar 8/4 x 12 lumber end

3) Scrap 2x4's and plywood and drywall screws

4) Old wideband radio parts with S48 servo

5) Scrap wire and pins for pushrod.

6) Large engine test stand mount.

7) Dubro 16oz tank

8) A few screws and rubber bands to hold the tank and radio bag.
