Guys,
We have to watch how questions like this are asked and by whom. New sign up of the forum asking about a remotely controlled vehicle to travel a long distance.
Could easily be a terrorist fishing for technical information or an enemy of what ever country you reside in.
Yes, the information may exist on the net and be available, but do you want to be the one to provide it to them?
Technology like this is controlled under export laws of the USA, and even if you are in another country they could still controlled by the USA, sorry but it does work that way sometimes. Your own country will have similar laws.
Even if you are not familiar with the technology export laws you can still go to jail for it, if technology is passed, without the proper license.
Beware, the old saying "Loose Lips, Sinks Ships", still applies just as much as during the previous wars. The world is still a dangerous place.

Terrorists and enemy nations already have all this information and technology available to them, and no, it is not controlled under export laws as a lot of this RC stuff we use comes from the Far East anyways. China has no qualms about selling to questionable clients.

By all means, ignore these pie-in-the-sky threads started by one-hit wonders, but don't pretend it's because the NSA will kick down your door if you tell someone how to plug a servo into a receiver.

Not entirely true, for example, you could put everything together from commercial parts from China, like a model airplane with a camera on it, sell it to a foreign national, and you just provided them with a remotely piloted drone used for surveillance.
That is a violation of the export laws and can be prosecuted for it. In the US and Canada, products made in Canada can and do fall under US export restrictions also.
Even though someone else may be doing it, you don't want to. it is the FBI who will be asking the questions.

I agree with the one thread wonders with some obscure question which no one else is doing, sometimes I say to myself, if they have to ask, then they do not have the technical ability to do it anyway, no matter how much help they ask for.

If the OP is not a troll , they could have clearly described what they want to do. At least they had the decency to make a suspicious request for information like a good terrorist.

Reason for this was my first question on this forum was because i asked the same question on local forum for rc/hobbies. And one of them referred me to rcgroups.com , and said i should try to ask them about it. So i did

Anyway, found what i was looking for, thanks to some users here and lots of research.

R/C reception is pretty much line of sight. If the model is beyond your ability to see it, what is the point---?

looks like more an unmanned warship than a RC boat, with GPS guiding system. Even more, with sonar system to avoid colliding into rocks or anything else.

Just as a point of interest about the discussion about long range control of model boats, and why we must turn a wary eye to persons who ask about such items, is due in fact of terrorist implications.

Many years ago, before the DRONE craze, I had a visit from the local FBI agent to my hobby shop, who requested that if a person, unknown by me, (not a regular customer), came in looking for a remote controlled plane or car that could in fact carry packages any distance, to take note and notify the FBI of the person and the sale information. This was before 911 which go to show that they were thinking along the lines of a terrorist attack with a radio controlled vehicle.

With the advent of drones, and now with the capability of programmed GPS control, I can see where the threat becomes very much more real. .I do not think it will be too much longer that we will see a crack down on the proliferation of the drones of all types, where the operator can be taken out of the equation for the operation and flight of the drone.

Guys,

I am sure, they (various gov. agencies) monitor RCG, and other similar sites. Plus, they occasionally "visit" us, at our club runs. We have had the same requests. Just "think", before commenting or answering.
