RE: Sig 1/4scale C/W Cub build
Those are gonna look really good. Of all the Cubs out there, no matter how good the scale, the engine is always the shortcoming when it comes to detail. I built mine (1/5 scale) from scratch, and used pictures I made of a full-size cub engine, took measurements with proportional calipers. It took about a week. I look forward to seeing how yours comes out, I have a BUSA 1/4 scale J-3 to build down the road, and the website you posted looks great, especially if he might have a laser cut kit for the engine soon.
