There is a 3/4 of an inch difference between the top and bottom. I measured from the back of the bulkhead for the nose gear to the rear end of the bulkhead where the servos mount. The bottom was 8 1/2 inches while the top was 9 1/4 inches. So it is worse than I thought unless I am missing something.
bluemax,
That doesn't seem right. If you are referring to the former where the stock nose gear would normally mount it can't be that far off. The stock nose gear block bolts directly to this former which puts the wire pretty much 90 degrees straight down. Maybe you got a Monday or Friday version.
