I don't have a definitive answer regarding the expected life of the rotor (magnet strength). I see no difference in current draw / rpm @ = volts / temp between Hacker motors with <300 flights and those with >1000. Here are a couple of links to info regarding temp related loss of strength in magnets: http://www.mceproducts.com/knowledge...-dtl.asp?id=23 http://www.coolmagnetman.com/magstren.htm It appears that general operation of our motors is well below the temp where ''demag'' is to be expected.
