Nova is an "Almost Ready to Fly" kit that I bought primarily to fly as a two-stage rocket using the Estes B-55 booster.
This rocket flies great and the booster stage has ignited the sustainer every time.
In medium-size or larger fields I use a C11-0/B6-6 combination.
At upcoming Club meets I plan to try a D12-0/C6-7 combination and see what happens!
Fantastic D-powered boost. Second stage was awesome fast! Booster recovered within 25' of launch pad. Second stage drifted 200+ yards down wind!
