Well, after an eventful day at the ME regional today I have to thank Paul Wragg.
As my Durango parted company with its rear prop pin half way down the straight on the warm up lap, it cut into the LiPo and produced possibly the biggest smoke cloud I've seen from an RC car!! (very spectacular).
I pulled it to the side so something could be done with it only to hear people saying "I'm not touching that!!".
As I ran from the rostrum I saw a figure running through the smoke towards my car. Mr wragg was the only one brave enough (? lol) to plunge his hands into the depth of the smoke and unplug the LiPo.
Thank you Mr Wragg. You probably save my car from imminent death!
