38 miles is not enough for a loepard !!
exemple :
a tiger1 could ran with 1 fill up a 100miles off road.
3800 ma battery = 38 scale miles ,so to be at the scale for effective range for a tiger1, we would need 3 x 3300ma batteries or 2 x4800ma .
for a loe , it should be even more.
that means my tiger1 fueled up will cost me over a 100$[:@]
