Re:Hell of an achievement. (Score:5, Informative)
As a R/C modeler myself, the specs of this plane are basically what I learned to fly on. Think: standard trainer with an O.S. 61 engine. This sort of plane can typically fly about 20 minutes on a tank of gas, and never more than about 800 feet in altitude, and never more than about a mile and half away. Things you have to worry about are:
1. Running out of gas.
2. Having the temperature conditions change the performance of the engine, causing it to stall. (It is not uncommon to tweak the fuel mixture on a model airplane on nearly every flight through an afternoon of flying.)
3. Such a small plane is susceptible to fairly small gusts of wind that can make if fly off-course, flip it upside down, etc. Anything more than about 15mph wind, and most model airplanes get tricky to fly. Especially if it is gusty (i.e. not a constant wind speed/direction)
4. Battery life - standard R/C batteries will last for about 2-4 hours max.
5. There is no way to restart the motor if it quits
6. Things can (and often do) come apart in flight. These things are made of balsa wood and heat-shrink coating. I've had planes explode in flight, wings come off, tails come off, etc.
Now, take a model airplane that is only about 5 feet long and with a wing span of 6 feet, and operates as described above, and modify it so that it can:
1. Fly continuously for 40 hours.
2. Fly through day and night in a variety of temperature and moisture conditions and not have the engine quit, or have to adjust the fuel mixture (since you can't do that in flight on the TAM models)
3. Navigate 1900 miles by itself, negotiating mid-Atlantic weather, variable wind speed, variable wind direction, variable air density, temperature, etc, with NO help from a pilot.
4. Somehow provide power for all of the electronics for 40 hours
5. Somehow fit 5.5 pounds of fuel, plus standard R/C radio, plus a home-grown GPS auto-navigation system, plus an alternator for the electrical equipment, plus two telemetry data systems, plus the computer to run it all into a plane that only weighs 11 pounds (think: two bag of groceries) and not weaken the structure so much that the whole mess DOESN'T fly apart on you.

The primary benefit of a vehicle that uses the water as its transport mechanism is that it can't crash! It could stay a few dozen meters below the surface for optimum travel speed and emerge from the water at intervals to update its position by GPS and wire that and other data such as temperature, atmospheric pressure, wind speed, and the like back to the crew on land.
Once nice side effect of traveling in such a dense medium is that a great deal of instrumentation weight would be okay since it's easy to make things float in water. The same cannot be said of the air! That means it might be possible to use a device like a gyroscope to keep track of heading while under the surface. Try loading something like that onto an RC airplane and you'll need some big wings.
