ET! A mold is a cavity into which you apply the desired amount of glass, it ISN'T a GDF Viper fuse off the rack from what the attendees tell me. It is lighter. The wing is different - 6 or 8 inches more span for some extra area and laser cut wood vs. foam core / balsa / carbon spar or injection foam / Obeechi etc. From what I hear it is right, IE - not stressed for 200 mph...
And if you were designing from the ground up, you would probably size the fuse differently in the first place. The original was designed to accomodate the head of the ICDF engine and the tanks and the weight of that setup.
Given a clean sheet of paper, you will get the next level of performance. That's the BVM way. Why he makes his own ICDF engines, his own retracts, even his own filler valve!
