installed fuel tank and engine. pretty basic stuff but i thought i would show a little trick for those that may be interested. i cut the fuel lines pretty much the length i needed before passing them thought the firewall but then i had a difficult time reaching them. so i used a bamboo skewer inserted through the fuel line holes and into the fuel tubing. then i just had to slowly work them them through the holes with a slow rotating motion.

pic 2: OS52FS installed. yes, no dummy engine yet. i won't make that until after the maiden and i know she flies well enough to put the effort into it.

pic 3: added a smooth card paper cockpit floor and backrest. also, covered and glued in the headrest fairing.
