Here's another modification that you might want to consider if you're building the Super Kaos: Lower the stabilizer position about 1 inch.
I have a Super Kaos originally built in 1981 with Goldberg retracts, a Wing Mfg. canopy, and an Irvine .61 (still in flying condition). This single plane has been flown with 3 different stab locations. (1) With the stab in the stock location on top of the fuselage, the plane would pitch toward the belly when full rudder control was applied to hold knife-edge flight. (2) With the stab relocated to the bottom of the fuselage, the plane would pitch toward the canopy when full rudder was applied during knife-edge. (3) Now, with the stab located 1 inch below the top of the fuselage, the plane will accept full rudder control to hold knife-edge, with no need for elevator correction.
Note: The Dirty Birdy incorporated a lowered stab position.
If you have a stock-design Super Kaos that pitches toward the belly with full rudder application (and you don't have a fancy radio transmitter with computerized mixing), you might try adding 1 inch (height) "skid" plates at the tips of the stab, with the plates running the full chord of the stab-tip, and extending down from the bottom of the stab. This mod can help eliminate the undesired pitching. If the mod. causes the plane to pitch toward the canopy with full rudder application, shave down the height of the tip plates 1/8 of an inch at time, and recheck the plane's response to rudder application.
