@the public
the (low) drag-coefficients are calculated for a perfect smooth body.
In reality (especially for the VIIC-body) the cd-values are a little bit higher,
because of body-roughness (ceilings, cannon, flood-openings, body-paint, fouling...)

P.S: Lost my money on E-Shore in trying to get an old 27MHz radio control system ... instead of throwing good money after bad i ordered a 12channel 2.4GHz from outer space in the east. That necessitates an redesign of the antenna routing to the surface. [Sigh]. On the other hand i get a pressureless diving tank for free ....
