New Project?

[Brandon Atwell]

Trying to find some RC SVG files and stumbled across this.

Doesn't give any bore/ stroke numbers, or any sleeve pictures in the previews. But looks to be a super cool project, $5.80 for a download....

It's tiny as the measurements state: 3D model size: X 10.8 × Y 17.4 × Z 8.22 mm
So 0.4 by 0.7 by 0.32 inch.. More a model of a model... Smaller then the old cox engines used for line flying
