I get 3 runs out of a 180mah lipo receiver pack on my BD. So apparently not only is my 180mah pack powering my car, but the BD is charging it as I run.
And for a guy like me that does not own a laptop, a tekin will cost me as much as 2 BD's.
Tekin+Hotwire+laptop = 2 Advanced speed controls.
It is a year later and the same conversation is still going on.
