I am a strong believer in A8-5 motors. Most rockets

I am a strong believer in A8-5 motors. Most rockets actually can use the longer coast time anyway. If you know how to piston launch rockets you are always looking for a longer delay. When I do group programs of 100+ motors I always use rockets well suited to A8-5 and B6-6. The smaller fields and the ability to recover and refly your rocket easily makes lower power, longer delay motors optimal.When I do group programs each user flies at least 2 flights, and on average closer to 4. Estes is uniquely positioned to serve this market.
