    Could anyone tell me the approx. nose weight needed for an Estes Phoenix? Mine has been built for over a year now but not flown and I'd like to fly it soon during my vaca week. The instructions have been misplaced as well as the clay that came with the kit. Any help would be appreciated.

    Download OpenRocket and use a sim file for the rocket to add mass to the nose and determine how much you need to balance it. The Phoenix is a very tricky rocket to balance. It needs just over 1.0 cal stability to fly and NO wind.

    Depends on which model OP has. The Jim Z link has three sets of instructions. The third set lists two pats of clay weight (check page 14 of the pdf), the other two don't. OP, if you've got the version that needed weight, Estes clay weights are .25 oz each. So, I think you need 0.5 oz in the nose. If you've got one of the other two, then you might not need any.

    It wouldn't hurt to follow Arsenal78's advice and use OR, either.

    It’s the older Estes Challenge series kit.
