    Where is the fuel cell in the NP01?

    You access it by taking the seat out on the inside. 2 barriers (3 with bladder) and more distance than the 818 from the motor (more than double). Plus no hot headers inches from fuel cell- that's why I moved mine on the 818R to passenger compartment. Better weight distribution also.

    Our experience is that you are not going to change the weight distribution, once corner balanced and a cross balance of 50% the distribution of the 818 will still be 40/60 with the tank anywhere within the roll cage area, as we played with this and no difference. Moving tank up front out of the roll cage area may make a difference, we did not play with that.

    I should of been more clear. I was talking fuel load offset.

    So the cause of the failure was a broken shaft, the exhaust side of shaft broke, not yet sure why, still looking into that, but the good part was that the compressor side stopped spinning so little went into engine and there was no chunks of fins or other debris from the turbo. as all fins are intact just bent and the VF30 uses thrust bearing so no ball bouncing around in there either.

    I'm thinking of a VF43 since it has a thrust bearing.
