Wow.. thanks I found it. Looked at that several times and over looked it.. Thanks againThe manual shows the link's length with the ball ends on them... see chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.horizonhobby.com/on/demandware.static/-/Sites-horizon-master/default/dw10841936/Manuals/BLH6150-manual-EN.pdf
I would suggest also looking for a setup video that someone may have made actually showing more details.
I have a PDF and didn't see that info.. thanks
