The recent discussion on this thread has helped me to shape the details of my ‘so-called’ stage 1 experimentation. I now realise I should include some sensorless motors in the trials too. This should help to answer the questions I pose in my previous post relating to ‘cogginess’.

Recap: stage 1 uses commercially available in-runner brushless motors plus a commercial ESC (electronic speed controller). Wireless control is via a commercial Spektrum DSMR transmitter/receiver combination. Track power is either 7.5V DC or 12V DC with step-down to 7.5V via a commercial high efficiency buck converter. A smart LED as discussed elsewhere will provide stay-straight/lane-change commands to the in-track lane changer electronics.

My next post will show the hardware configuration for ‘stage 1’ plus, hopefully, some on-track results. This may take a few weeks!

Meanwhile, I'm happy for the debate to continue on this thread - that’s the way we all learn from each other :)

ps the unloaded max wheel RPM for the 5500KV sensored brushless motor running at 7.5V is 18,200 RPM as measured by tacho. Transmission ratio is 31:13.
