Eric builds a modified mini IFO
The original plans called for a pull/pull system for the elevons. Too flimsy for my launch and crash style of flying. So, I used the same technique used for the trainer IFO of carbon rods.
Also, notice the white tubes. These hold the rudder on. The original plans had much shorter, poor fitting tubes. I found tubes which fit the rods perfectly. This way, the rudder does not flop around at all, and is firmly attached.
