that is a good question. In all the testing I have done (and there has been a TON) I have never needed a RX pack for the boat on 14cells. having said that.. I also have found that the addition of the extra voltage did not add anything to the "fun factor" of the boat. I run my SV on 12 cells and leave it at that.

IF you feel it is best to use a RX pack then by all means go ahead and get what you want. That works too.

ROCK ON
