here are some videos of my sub running in the local pond. the first one is when she was still in primer and still working out alot of the little issues, and the other is when it is completely done except for the ballast system which i am still fabricating. both of the video my younger brother is driving i need to teach him how to operate the camera instead of my sub.

Great build. Kinda reminds me of those egg-shaped model planes.
Looks a bit stern heavy, nothing a little foam or ballast shifting can't fix.

she is a little stern heavy right now but it dosent have a ballast system in it yet, and the only way to keep it under water is to trim it like that but i hope to put a snort air ballast system in before summer. if i do take the weight out of the stern or put more foam in there the nose dives down and then it nose dives when i try to dive, am i doing something wrong or do i just need to find that perfect amount of foam and weight?

any photos of the insides? Very much interested in the sealing method and motor you're using.

only one pic of inside right now made the wtc out of lexan i know everybody is using tubes but i like the idea of a box it just seemed easier to build and put electronics in, so far havent had any problems. right now im just using a cheap low rpm motor from aqua craft but eventually i want to put something better in so hopefully before next summer.

since this pic i have put in a Sambra labs receiver and did a little bit different placement with wires but its pretty much the same now as in the pic.

here is some new pictures of the sub. i made new stern planes and put in some new electronics along with a dual battery connector so i can run two batteries at once for longer run time. so far everything works great only had it in the hot tub...... pool has been closed all this week due to snow days. so hopefully tomorrow i can really test it out.

I'm amazed how you maintained a nice level submerged run.
