Re: Looking for slip rings and distributors

For reference, we did not use the Mercotac slip rings during the season but did test them post season. I also contacted Mercotac years ago and came to the conclusion that we would be running them above their specifications. Mercotac has multichannel units and we could have run multiple circuits in parallel but those get big, heavy and expensive. Ultimately we read the rules to say mercury was not legal and didn't want to hinge a design on that risk. Once we found that Bomb Squad ran the 230's all season with no issues we decided to test them ourselves post season. If First specifically disallows the Mercotac slip rings and lifted the COTS slip ring rule we feel that we have a good alternative in the two designs we've posted on CD. These could be 3d printed by the teams and assembled or if Andy has his ears on... There are also windmill slip rings on Ebay that we have evaluated and would handle the current no problem but they are big and heavy.
