RE: Repairing a broken stab - need help please
Don't use a drill use a piece of heated piano wire, experiment on a piece of foam to find the right temprature, do not worry if the hole is too big you can use an expanding poly foam glue to take up the difference and glue in the carbon rod at the same time, IMO if you use a decent size carbon rods or tube (lighter and just as strong) you do not need the flying wires, my 2M Extra has only one 3/8" carbon tube inside the manufactures ali tube, this was meant to be a permanently fixed tail but I made it removable, I have had no problem with the tail, Just make sure your alignement is spot on before you start gluing everthing together, if you have diahedral on one side break it off and start again. If you can remove the tailplane from the aircraft and do the whole job on a flat surface, it will be easier in the long run.
