RE: rcmk s-520 has anyone run one of these yet
Also I dont know what hull you plan to use but 70 mph crashes with that much added weight in the standard fiberglass hulls just doesnt cut it. He went througha fiberglass hull inno time.you need to go with carbon fiber and possibly add a bulkhead. the pictures here do not show that but we added one later. Havent had a single problem with it since. Remember longer is better.
