Hi periscope lost the iternet but just got it back online. What you said is right and i fixed the front dive planes and had the rear planes rc'd. You still need a bit of speed to dive put you dont have to go as fast to go as deep. Once you rech a speed at each you dive you can dive all the way to the bottom at that speed. If you use standard 2 channel operation you must keep accelerating to go deeper and the deepest you can go is 1.5 feet.

Hope this helps

P.S Look at my failsafe thread.
