i think its ok now. thanks Os. i just installed the 500th motor today. the tail is now holding solid. except under extreme punchouts. i think that due to the 65hb's for tail servo. i'm using the 13t for pinion at the moment. that is working well. it also has the superskids on it. but i like the look of the stock landing skids. i have a set and will put them back on. cant wait till her again tommorrow.
