One of my reasons for getting into RC is my interest in electronics...it seems to me that there is alot you can do to add to a plane that you can make yourself...

My question, not knowing how this works, may sound dumb...

I know you cant reliably check absolute fuel level as the plane moves, but is it possible to check the fuel pressure. Im not sure how this works, but i know that in racing, the fuel is given as the pressure, since the motion would mess up a traditional reading...is this possible in a plane?

My idea is simple...i know most people just time their flights...but im always looking for different ways to do somthing...and i thought why not have an on-board monitor that reads the pressure, and when its drops to a predetermined point, you would be signaled by means of a low-voltage LED Strobe on the outside of the plane somewhere...

If thats not possible...i would probably do something for an onboard timer that alerts you in a similar way...

Before you say its overcomplicating something, i know....i know....i know.... but the materials would be light weight, isolated from the radio gear, and simple...not to mention a little cool....
