Two things and then I have to get to bed. I have to be up in 4 hours and have stops to make on my way to work, making the drive 99.14KMs to and 75.64KMs back home and costing 15.82 litres at £.78 per or £12.34 for the trip
Getting back to the subject at hand, I knew Airtronics servos were wired differently, didn't know about Spectrum hence the question. I've never been a fan of mixing brands due to issues that existed when I got into the R/C hobby so this is unknown territory for me. As for the gyro, I knew how the mechanical ones worked since mechanical gyros are used in the artificial horizon indicator on full sized aircraft and it was easy to describe. I know Piezos are the norm now but not how they work so, rather than give wrong information, I went with what I knew to be correct and easily understandable. Now, time to find a pillow.
Later guys
