Guys just want to say thank you for the great imput and will be taking your advice. I will ensure that the cap is removed when charging. That's why I have joined the sub forum, to learn how to use rc subs correctly

For some reason the pics are at an angle , if you click on them they straighten up.

one thing i am noticing is i am getting a vacuum between the tube and upper deck if anyone has had this before let me know and how you dealt with it thank you

Did you open any holes in the deck or in the tower?

[Mikesmatrix]

Hi yes put lots of holes in deck and have now put a few holes on the deck of conning tower I'm going to try again. She goes up and down. She sits at water line but after going down she is fighting to get past the larger holes at sides if I pull her up past holes you can here air rushing in then she sits at water line again

I'm sure with her running forward she will climb up. Tried again static and still getting a vacuum. I have trimmed her so she sits with a quarter of the conning tower out of the water so she is buoyant with full ballast. Just had to add a small piece aft above the water line so she goes up and down flat thanks for your reply . I am open to any other ideas.

make sure the underside of the holes are chamferred (like a countersunk screw)... it may help with surface tension of the water on the holes.

Thanks for the advice. I thought I had her trimmed but drilled 4 more hokes in the conning tower side prices and there was air trapped in there so now she fully submerges on full ballast. I need to add foam in conning tower to have part tower sticking up at full ballast. Cheers for the advice

I also need to drill more holes in aft top deck . Air is moving around under there. After diving at conning tower depth the bow will be slightly raised. I add foam to aft above water line on boat and balance it out when I dive next time to conning tower depth the stern is to buoyant under water and bow dips down I'm guessing air is not all escaping and changes balance each time.
