Built by a famous modeler, Pierre Kerjean.
Seen in 3 issues of the french magazine RC Marine.
Scratchbuilt hull and diving system (no kit)
Baxter ballast system with autostop
Retractable and working bow planes with safety system when retracted
Automatically deployed when the ballast is full

The builder chose this config to get the best turning radius.
A blue LED indicates that the pump is in working order.
Of course the stern planes works too.
Model+radio+charger included. I have some instructions the builder made too. and few drawings.
Here are some pool pics...
