Default Engine Break in

Well considering that a ringed engine has to be run for quite some time so slobbering rich it's unflyable there's no point in wasting money on high nitro fuel. I always use a straight 80/20 all castor but a mix of castor and synthetic is fine. The 15% nitro will only hurt your pocket, not the engine
