its a good idea on any chain run of this distance, regardless of wrap. Chains stretch considerably, and do crazy things under power. If you are planning on having seperate chains running to each module, and mounting space is a concern, then you can use this design, with a sprocket floating within the chain

If it is just one piece, then you will probably need a idler to get enough wrap around the globe anyways.
