Hi I have a manual for the Gaudius however it is different than the kit, so on the ailerons you will have to install the servo first, then enlarge the slots for the servo arm, now you will have a reference of where to put the aileron horn. It just glues on inside of the rear wing spar. Be aware that the aileron servos go in backwards by that I mean that you will be looking at the bottom of the servo not the top as one would think, the factory installed slots will have to be made larger also as they seem just to be a reference. Hope this helps.
