Hi guys this is my first post and i would like to say what a great site, i found it while doing a Google search and its great to read your posts i am sure i will learn alot from you guys!. As a complete newbie to this field i have an idea about building an rov based around the fishing video cameras linked via a 200 ft tether to a 9'' screen as seen on eBay for around $160 Aus and from there build a frame with r/c motors for control but my main question is i read some where that i can use my 9 channel turnigy controller to control the rov via receiver /speed controller and servos is this possible and to what depth and distance would i have control under water ? .This is all new to me so any advice is welcomed cheers Andy

@trinescape,
Welcome to the Forum.
2.4GHz signals do not penetrate water very well, especially salt water, so unless you have the R/C receiver antenna on the surface you will not get much in the way of depth before losing the signal.
I had a submarine that used a 72MHz FM R/C controller and I was able to dive to about 5 feet before I lost control of the submarine. The R/C Receiver antenna was in a waterproof tube that extended about 18 inches above the submarine's WTC.
Regards,

I use an older 72 mgz JR rc transmitter that has a training jack on the back that will control all channels via 2 wires directly to the receiver. I have tested it successfully on a 400 feet telephone cable, but not under water because I am still building the ROV.
I am also experimenting with model railroad 'DSC' which allows many functions via 2 wires. This will allow fine control of my robot arm gripper (also being built).
BYW, great site - I have really learned much from many people.
