I beleive this is an evolution outrigger. A guy in massachusetts used to build and race these in the early 90's. I had a grand prix cmb 90 in it originally, and it would turn a modded H 50. Hence the name silver bullet, it flew. But it got tired and parts arent available for the grand prixs anymore. About two months ago i installed a CMB 1, new stuffing tube , strut, and complete radio including 1/4 scale servo. Now everything is new again. I have only run it maybe 4 times and it still needs break in. The break in prop is still on the boat, but it will come with others. I am slowly selling my boats, i dont have time anymore. i am asking $975. obo plus buyer pays for shipping
