Ernest,
Getting the water to and from a remotely mounted radiator is not as big an issue as getting enough airflow through it while on the ground taxiing.
Chances are the engine will overheat before you even get to the end of the runway.
How do you propose the cool the engine on the ground?
Just curious, as Kelly Troyer was comtemplating remotely mounting his radiators too. I don't know what he finally decided.
Picking the air up from the wheel well's rear wall, and dumping it at the rear of the turtle back.
Nearly half of the prop is pushing air under the plane, and the plane sits at about 8 to 9 degrees incidence on its gear. Even on the ground, there is going to be a high pressure area at those wheel wells, and if the prop is turning, there is going to be a partial vacuum near the end of the turtleback. It won't get full flow like it will in flight, but I'm confident it will be enough for ground operations. If it is not enough, I'll get 'creative' with wheel fairings or gear doors to direct more air down the intake...build in a scoop that gets retracted with the gear.
You mentioned the exit path as near the end of the turtleback. Is this on a Dyke Delta? I don't know about the Delta, but on most conventional airframes the top of the fuse. behind the canopy is actually a *high* pressure area. Have you checked this out with the designer of the airframe?
