Sometimes I set the roll trim 1 or 2 clicks to the right depending on what model.Take the long ranger for example I always have to set the trim tabs a little forward and to the right on the cyclic trims.All models vary a little.but most require no trim adjustment.Some times I shift the CG on a model to correct flight charecteistics,Actually only one the sun dog. I moved the CG forward .5" to get the heli to fly stable in inverted flight as well as upright and the cyclic aft a few clicks, now it hovers dead solid bolth ways.It just takes some playing around and soon it will all be second nature.[sm=spinnyeyes.gif]
