I started doing the aileron linkages last night and IMHO the 2mm rods are not strong enough to take the flight loads I'm planning on for this model so I installed 440 rods and the MK horns. It stiffened up the whole assembly quite a bit. I am a little worried about the pull/pull elevator linkage even though I used the MK horns. Everyone I have spoken to says not to worry but I have an uneasy feeling about it. I guess I'll know if/when it breaks.
