Hmm it would be a great addition, however the starboard side is exactly the one where the hull will be opened, and the very same position of the pillenwerfer is approximately 1,5 cm away from the rear end, which brings it to spot where the cut out will be, and i have no idea how could i add it, obviously it cant float in mid-air, unless if i could make some kind support for it., maybe if i would add thick piping on top of the torpedo compensating tanks, but that would not look esthetic in my opinion. Transparent holder is also not really appropriate, since it would be visible, should i leave it out?
I'll get to the E-motor cooling fans for now, and will wait for your opinion regarding the pillenwerfer.
