does drag brake use up any battery power?

[blueb8llz]

i currently have my drag brake off, but if i set it to 10%, will i notice a slight decrease in runtime since instead of coasting (which uses no battery) now its applying some brake. also what are the advantages and disadvantages to having a drag brake set.
to me one advantage is, i liked it how on brushed motors it wont coast that long..and the disadvantage would be for jumps...it will prollly bring my nose down.
