The D5 versions of these kits were very short lived and no plans were posted. They tended to spin a lot and occasionally would be headed down under power. The spinning also could cause burn-through of the thin walled, long burn motor. I think Art eventually decided that having a few kits for the D5 wasn't worth the trouble.
OOOPS! As it turns out, I'm responsible for both entering those into EMRR AND was supposed to be responsible for tagging them as OOP. My bad. I'm glad you caught that for me
I personally know of no kits for those motors, although there are many you could convert.
