Joe as a after thought Ive just checked the XYZ site and there break in oil is 30/1 when breaking a motor in Ive found the best way is in flight let me ask you a question if you buy a chain saw or a weed eater do you start it up and let it sit on the ground for two tanks ( i think not ) when flying at half throttle there is far more air passing over the fins than will ever be gained than on the ground.
ZYX do suggest running half a tank of mineral oil to help bed the rings which i would agree with for the first start after that its 40/1 again all my motors run on 40/1 DA85 DA100 and DA70 plus DLE55 and the XYZ53.
