Short life! The friction on those little brushes kill them relatively quickly. On average, you get 100 fligths. Sometime up to 300 flights, but also sometime less than a 100. So you replace them and keep going. Brusless motors last a VERY long time unless you drive them too hard (too much current).

It doesn't mean brushed motors are a bad choice... Most UM airplanes do not last 100 flights and quite often get destroyed before the original motor die! This keep the cost down, and so far, there's not really any good brushless motor that work on 1S battery anyway (that doesn't cost 1/3rd of the price of the whole airplane)
