The simple adjustable weight system shown was added to an AC Slayer 49" Mono which uses a 35 cc Zenoah & a Performance Unlimited tuned pipe. The hull could not be balanced to the designed balance point, 17.5" from the transom, after adding the 3 " diameter, 11 degree baffle tuned pipe & muffler. This was after moving the engine, radio box, fuel supply, etc., as far forward as possible. By placing the newly designed weight cavity 16.5" forward of the designed balance point, a single 4 ounce brass weight balanced the hull. The cavity, made from a 2.000" ID X 3.350" deep tin can, which is epoxied in place, could hold three .750" thick weights with a maximum OD of 1.760". These removable weights are sitting on the same size .625" carbon fiber rod used on the cat's weight system. This rod is threaded into a glued in PVC base plate with a 58/11 nylon thread, & it is removable. The machined PVC cap is located on the ID of the .625" OD carbon rod & the ID of the tin can cavity. Radio box tape is used to seal the machined PVC cap. The entire system was made in less than I day.
We will be testing the system this Friday & Saturday, 6/8 & 6/9, 2019 at the Suffolk, Va site.
