Cheers Hotshot III
Thanks for the tip fella, gaffa tape is also now packed in amongst my ever expanding hauler.
TBH from what I have read and the advice I have taken from some mates who all run 1/8th EP buggies, with a mindful corner exit trigger and sensible ESC set up I am hoping the 20mins is achievable. I'll let you know fella, how it goes in a couple of weeks when I have a meeting lined up.
I chose to gear up to achieve circa 45mph in the knowledge 1900kv run on 4S is less power hungry than a 2200kv on say a 16T to achieve similar top speed. All will be revealed when I hit the track if my gearing suits me and the track layout.
If you've not seen or used the RC calculator at the link below it might be useful or of interest, certainly helped me get my head round which range of pinions could be useful with which motor.
