Mainman presents a yellow Vic Viper, dedicated to Nate Nielson, who passed away in April.
Nate was a prolific builder. More about him here, here, and here.
There was a memorial fly-in at Brickworld in June and another one at BrickFair in August. There will be a final fly-in at BrickCon in October.
UPDATE: Mainman posted an exploded view, for those of you who are interested.
