I haven't had a look at the pinion yet as I have got my son a tracer for his birthday and if I convert mine now he will get the hump lol.I will run it in stock lay out when I convert it but its something I could consider in the future but I am pretty sure it will be quick enough with the 1300mah li-on battery as it powers it nicely in the brushed set up.Silly question but when using it brushless I take it I want the esc out of lipo mode and in nimh mode?
