Actually very easy, took the two halves of the broken stab and cut them the same lenght. Got the correct angle (anything between 110 and 120 is good), glue the two together, then trimmed a piece of wood at the correct angle to glue in the middle. Just for a little more reinforcement, put a small piece of plywood inside fuse and ran a small screw thru the center stab assemble after glueing all on. Had to also shorten elevators a little to fit.

Although I used to race pylon with V-tail planes, I kind of did this as an experiment to see if there was any big difference in flying. I expected some tail wag and less sensitive elevator , but plane flew excellent, almost seemed to be more stable. Had to add a little tail weight, I guess because I lost the fin and rudder.
