Bought this as spare replacement for my Formula Tuned Motor. Those manual said these brush must be replace after 15 or so pack of battery, personal I think it can lat more than that. Get it before you brush need to be replace. Must Buy.
Escova de otima qualidade, sempre subistitua as escovas velhas do seu motor por escovasoriginais Tamiya, é nitida a diferença de potencia do motor com escovas novas.... Essas escovas servem em qualquer motor tamiya standart.... vale a pena manter algumas para reposição..... Recomendo
Great replacement brush for any standup brush motor.. increases power hugely once a new brush has been worn in because of the extra pressure on the comm because of the extra length. the tamiya brush is a very good brush and they wear evenly i am very happy with the product and will continue to use tamiya brushes.
