Thrust Vectoring?
 

In jetplanes (eg F22 Raptor) the military uses thrust vectoring to make fighter planes turn more sharply. Essentially, they can control the direction of the exhaust flowing out of the jet engine by directing the "nozzle" of the engine in different directions. To go up, the nozzle moves into a downward position etc.

I dont know how much thrust is generated by an RC engine, but theres is definitely some at full throttle, and I'd like to make the most of it....

Anyhow, for a straightline RC boat racer, the placement of the tuned pipe would be ideally down the center keel of the boat, in as straight a line as possible....

But I'm working for oval racing - always in a clockwise circle. So wouldnt it make sense to direct my tuned pipe a few degrees off from straight down the keel? And specifically a few degrees to "push in" on the boat around the corner, resulting in driving the boat's outside sponson around the curves? Or would the opposite be better (seems to me that would drive the outside sponson down into the water more and increase overall drag, because in a corner, more weight is already riding on the outer sponson, and adding more push to that side would increase the imbalance).

I havent seen any thought given to this, so thought I would post it for everyone.

thanks

RE: Thrust Vectoring?
 

I don't think that the exhaust on a model boat would have enough thrust to make any difference. These aren't Harriers or Top Fuel Dragsters. T/F dragsters and Funny Cars do use the exhuast pressure for free downforce, up to 600 lbs of it, this is the reason why the zoomies are angled up and back.
If I can stop the engine just by placing my finger over the exhaust, that kind of shows me that there isn't a lot to work with there.
It really can't hurt to try it though.
