Some parts for the 1/48 scale G7 torpedos I’ve been designing and gathering parts for, for my type VII build. Hoping to be able to finish the first prototype soon and if successful, test it

George,
Thank you, but nothing new here that hasn’t already been done by many others before me. The nose and tail pieces are 3D printed parts I printed that I may or may not use as masters for resin pieces if needed. The design files for these pieces are mine that I created in CAD using declassified blueprints of G7A and G7E torpedoes.

Got the the internal chassis designed and printed yesterday that the motor, timer module, reed switch and LiPo mount to and keeps everything tidy and concentric to the rest of the parts. Tested the finished assembled chassis and everything worked as it should. Ran for 5 seconds then shut off. Just need to finish the tail fin section and mount the prop and prop shaft. Then hopefully do some wet testing after the ballasting is checked.

Unfortunately these are the largest size photos I have been able to upload without getting a “file too large” error message when posting.
The propeller is going to be a 3 blade design that I modeled in CAD from scratch. Have not been able to find a suitable size off the shelf produced propeller other than what can be found in small plastic ship models. I’m a mechanical engineer so it’s just easier for me sometimes to just design and build parts from scratch then try to search for a needle in the haystack.

Consider micro drone props-I am using 2 blade but you can get 3 blade also ...https://www.rcgroups.com/forums/show...5&postcount=15 -BG

It was an experiment at 1:64. Capacitor power, magnetic reed switch, composite body tube- with cap you don't need timer circuit or battery...but you do need to charge after every run-but charging takes 30 seconds! The smaller you go the more problematic the weight becomes. You want the torp to just float level when dead in the water Also check out the launch and charging system : https://www.rcgroups.com/forums/show...-give-it-a-tryLast edited by Bob Gato; 06-24-2020, 10:15 PM.
