  ok so the sensor doesnt have to be perfectly level because it will still compare the two readings right?

  ok i think i can use the wires that came with the plane. So i need to cut a ventilation hole where? nose? canopy?

  The wires don't matter. If the prop spins the wrong way, just switch two wires (doesn't matter which). As for moving the ESC, you need to lengthen the leads (solder on longer wires). Either that or move it inside the fueslage (ideally with a ventilation hole)

  oh and can you help me with my ESC? i dont know what wire goes to what. The motor wires are red, black and yellow so those are easy. But the ESC is just all black. There are A,B and C labels on each wire but i dont know where they go. I was think a volt meter would figure it out, is that correct?

  what if the sensor is near the tail end of the fusealage?

  I cant move it, its leads are too short. Its a 50amp ESC driving a 25amps motor. It cant get that warm right?
  how could i move it?

  Also, is that your ESC above the wing? If so, you'll want to move that, too. When it gets hot, it will throw off your IR sensors.

  The sensor needs an unobstructed view of the horizon on both directions and should be parallel with the forward motion of the plane. We mount it diagonally so its view isn't blocked by the tail, but the way you've got it it's blocked by the whole fuselage, starting with the canopy (the sensors have a >90 degree field of view each)

  well my gps is actually on the hood not the fuselage. But i did flatten that area.

  so it not being perfectly level wont matter? Its only off a hair
