Why some 400 motors toast.
watch your Mibushi(all 400s) that are marketed from germany because they like to cover the cooling vents,I cut back the sticker on the graupner shown .My U.S. marketed ones Zagi E- Flight,ect they are aware of the cooling vents and do not cover them up.(( From the people that brought you the Micro Jet)) yuk, Yuk
