Looking to build new fuel tanks for the Rocket and I'm putting together my BOM. The Rocket shares a common airfoil with the -4, -6, -7 and -8, so any of those tank ribs should work. Looking at the Van's store, there is a dramatic difference between the prices of the tank ribs between the models. The -7 is significantly less expensive (like half) than the -8, for example. Any idea why this is so?
