i just noticed on my copter x when i go left or right full rudder i start doing my 360 spins it starts out i gues u can say normal but the longer i hold full rudder the spins get faster and faster.....like a linear speed up on spins is a good way to discribe it....thats not normal right? it should go to MAX piro spins and soon as it goes full rudder right? unless this is normal
