Let us know how it goes.

20 hours is about right, that's how long it took to build my first one. The second one took about 8 hours, it was alot easier to see what was happening the second time around.

The hardware was also a concern of mine, the second kit I built was missing a control horn, (that or one of my cats drug it off, who knows), but thankfully the hobby shop had plenty.
