    What advantage does the bellcrank give you over using direct actuation? Is just that you didn't have room to turn the servos 90 degrees in the WTC?

        Yes, I could only fit these little 'microbe' sized linear servos with travel athwartship, hence the need for bell-cranks to translate the output to a longitudinal one.

            Hobbyist who convert 1/64 Hotwheels/Matchbox cars use these 1.7gm servos in lieu of those linear servos..

                Excellent tip, Romel. I'll look into those. Thanks.

                            Why does the paint have a mottled pitted appearance?

                                Fish-eye. Some crap got into the mix. It'll sand out. Goes away entirely after a heavy, well flattened clear-coat. Not my first rodeo. Ain't finished yet!!

                                    will make weathering easier. Marine growth and grime.

                                        David, that Albacore sail is outstanding. Truly one of your best yet.
                                        If you can cut, drill, saw, hit things and swear a lot, you're well on the way to building a working model sub.

                                                I woke up stupid this morning. Thinking of representing that 'city crest' we see at the leading edge of one of these boats sail.

                                                Some fine painting on decal film seems to be in order for the near future. Will be good to once again haunt my drafting-room upstairs. A fun departure from the usual grind of the shop.
