Hey Rusty, it measures 440mm long x 290mm wide x 250mm high, the side panels are machined from polypropylene therefore are buoyant, the frame is constructed with 15mm x 15mm openbeam anodised aluminium and all the fittings are marine grade stainless steel the front wtc i designed and machined myself from delrin, I had a similar wtc for the rear but decided it was to small for 2 batteries and decided to use BR end caps utilising a aluminium tube that I already had, I will need to add some form of additional bouancy, I do have some high density foam that I will probably use.
The control for now will be via my Rc controller and a pair of pwm-ppm fed to the rov then ppm - pwm to speed controllers / servo’s and an rccc board that can switch AV feed and control the lights and switch on the GoPro for HD recording.
Batteries just now will be 2 no 3 cell turnigy 5200ma/h in parallel.
Ideally I would want to control the rov via a ps2 controller pluging into the top box, feeding something similar to apm so that a osd can be introduced utilising the open rov pressure and compass module, and of course really need a good purpose built neutrally buoyant tether and an affordable price
So that about my plan any questions ask away.
