I want to add a rudder to my IFO MK 3. I am in the construction process at the point of adding the rudder. Has anyone added a rudder to it? I see the Trainer IFO has a rudder but can not see how it is attached.

I thought of using the 1/8" tubing supplied and mounting it vertically in the right aft corner where the fuse stick meets the training edge. Then add a third servo behind the 2 that are already there.

ANY suggestions would be helpful.

Thanks,
Jeff
