On the contrary, anything that can make these dammed electric things go away the better. the interesting thing is how you design the seal, not the rotors. The twin rotor idea is not new. From what I can see, I am the only person who has made one run for longet than an hour whereas single rotor designs such as Cross, Coates, Gabelish, Bishop and the like have made singles run for tens of thousands of miles. If you lived anywhere near me in Brisbane you are welcome to come and help but I have no idea where in the world you are. I need to make it a commmercial success yes, but I am not in it to make a fortune, already lost one so hey, not an issue. No, I am here to stop the march of theses battery powered items with the soul of a brick. So, for me, the more the merrier. Picking an engine up to start cutting metal whithin months now, in fact going to get the bsae engine whithin a month and start hard designs. Determined to take my bike to work and back on a daily basis by Christmas this year. If someone beats me to it, I will still be happy. Go for it fella.
