I have a recently purchased Venture 50 & have set all the linkages as per instruction with the swash level at mid stick & zero pitch etc. To get it to hover corectly in normal mode it is nescessary to give it a bit of left & back cyclic. In order to get the tranny trims back to center can you use the sub trim to set the swash of level or should you do it on the linkage or should it be something else?
