Piper 2 version 2 belt tensioning system

One of the additions to Piper 2 which is also backward compatible and may be used in version 1 is new belt tensioning system. Previous version have been using zip ties to tension belts so the only way of slightly loosening belts was to cut zip ties and use new zip tie. 

This picture shows intermediate version with tensioners on both ends of the belt. Final version has tensioners only on one side.
