The June '05 issue of RC Boat Modeler shows 40 reversing speed controls ; most are not for high cell count however. I replaced my Twinstorm's reversing control with the Jeti600 after I roasted the stock one. The Jeti works great with 16 cells, survived sinking, & I've learned to live without reverse. Also, too much reversing can push water back up the propshaft, be carefull there. Go to OE, get a Jeti, & 'git 'er done is my opinion.
