It looks like there will be a motor change for the Big Nuke. I weighed the Nuke for a final time with everything in it and the empty weight is actually 10 pounds and 5 ounces. Thrustcurve says that the J315 will work, but I am not sure. I am thinking about changing over to a J350. What does everyone think?

Your prepped rocket will weigh about 12 pounds, and a J315 has a lift-off T/W~6 where as the J350 gives it a lift-off T/W~12. The J350 has a much better margin to handle wind gusts which are likely in April in Amesbury.
