When a new Iron Builder competition starts up, it’s hard not to feature some of the fantastic creations that come from the parts-usage head-to-head. In this round, both our competitors are trying to best utilize the Technic rotor blade in red. In a strategic move, challenger Duncan Lindbo attempts to cut down his competition with a brilliant chainsaw creation! It’s such a clean model, with excellent lines and a superb use of the seed part. But the log it sits on is equally impressive, all knotted and gnarled on the exterior, yet smooth and ringed where it was recently cleaved. Good luck to Duncan and his challenger Dan Ko as they duke it out!
