Sorted - Well I think. Opened the motor endbell to find a blob of solder shorting the B and C wires together. Because this was in the endbell not the winds the motor wasn't getting hot but everything else was. I bodged a capacitor from an Ezrun (wrong rating but its what I had) and gave it a test. 4 minutes running before the insane speed caused me to break a wishbone, and everything is at acceptable (if on the warm side, but its a hot day) temps. Battery recharged to have used 2200mah in that time - much more like it.
Not sure the cap will hold as its not the right one but the car now works.
Thanks all, especially SMD for great service/advice, boo sucks to Modelsport for taking far too long to send my new transmitter.....
