So far the altimeter is a little disappointing.

First it is almost never zero or even a few tenths off at startup. Usually like -3.6 ft, which is a bit large of a variance for just starting up and sitting in a room without air movement. The tolerance should be able to be attenuated (?) if you were able to set the practical range of the sensor. If I have no intention of ever going above 1000 ft AGL, then its ability to sense pressure change to 50,000 ft or whatever is not relevant for me.

I put the sensor into a small block of open cell foam and it started counting down and kept going down to -487 ft. or something. Reset everything and it did it again. Apparently something occured when I stuck it in the foam. So I took the Spektrum sticker/housing/decoration off. I think the sticker was stuck to the top of the sensor or the micro-molex leads had poked through the sticker and there was some conductivity - heck I don't know.. But It seems for a few pennies more you should/could have put a small piece of foam inside to cover the sensor, which would help it be more accurate without the end user having to put it in a block of foam.

And finally, there is no way to get the DX18 to show the altitude and the voltage at the same time, which is disappointing. Even adding a 'current reading' to the telemetry min-max screen would be welcome.

Best,

Joe
