Paul.
You are absolutely right about using a trailing throttle on IC cars. I don't have much experience with IC cars, except the real ones, but certainly with electric it is far less critical.
In fact thinking back to our tracks I can think of perhaps 2 corners where we are actually on a trailing throttle for any considerable time.
I just got some more bits for my CGM today, including the lightweight blue motor mount - extortionately expensive, some more graphite diff wheels and graphite rear hubs.
We'll get that weight down eventually.
