i know a fella who has put the rd bladed arb on the rear of his s1
his not too impressed with the kit itself but it works for him
really cant remember what he is doing on the front
think mine will be custom made jobbie i think
thats made me think about the back as well now, bugger!
yeah, not sure about the front arb, the seirra one is designed to go behind the engine, with struts in front, obviously back to front with the esc, and i don't think the blades will be long enough????
