Flight testing is going well. I gained a few knots on the true airspeed by installing the wheel pants.
I noticed at altitude the OAT was reading about 20 degrees higher than it should be. The probe was installed in the very bottom tail, just in front of the tail tie down. I believe it is picking up exhaust heat in flight, since it reads accurately on the ground engine off.
I repositioned the probe under the right wing, at the middle access panel. This will keep it in the shade, and away from any hot exhaust gases.
Hopefully it will give more accurate readings in flight, which should give more accurate Density Altitude and TAS calculations.
