If you cut out your Trex canopy as detailed in the Align instruction manual you will more than likely notice that the aileron control levers attached to the swashplate will bind with the top rim of the canopy. There are several fixes to this. The best I heard was softening the canopy with a hard dryer and bending the now slightly supple plastic out of the way of the swashplate cyclic pitch control rods. On my own machine I made the modification pictured below, which although untidy does fix the problem. In a future dremel episode I may tidy it up :)
