Yes - we live in a world where it is often perceived as quicker to learn by ‘trial and error’.

When it comes to designing nRF based digital multi car systems… careful reading of the instructions/data sheets definitely makes sense :)

In designing a multi-car system (12 or 24 or 36 cars), with 8bit throttles and 100Hz refresh rate (frame rate) and frequency hopping… much of the 10millisecond ‘frame’ is spent switching between transmit and receive modes or changing channel - each involves significant settling times. 

In my prototype digital system these important settling times account for over 80% of the full 10msec frame. Consequently, data transmissions account for less than 20% of the frame - but happily this is more than sufficient to meet my system performance target :)
