i just finished my ultimate fx today. i did my maiden flight which was pretty good. i still need to make the pushrods from the lower ailerons to upper ailerons. i am running an e-flite s75 for ailerons, jr281 for the rudder and elevator. i have a 35a esc but with an e-flite 370 motor so i can't go full throttle or i will ruin my motor. my ulitmate fx is not super stable when i take off and land. every time i try to fly it upside down the plane flips me back over. and everytime i go into a hover it throws me upside down but then flips me back to normal. the last problem with it is that when i try to go downward it whips down to a 90 degree angle every time no matter how much down elevator. my motor mount stick was offset by a lot did this happen to anyone else? i will post images in a little bit
