I have seen E9-4 powered Estes phoenix missiles fly fine.
* Nose weight is needed to make the CG move back to where it was with the D12-3
This missile has fins above and below the CG, so if you do not line them up
they will act as "flaps" or "vanes" or "flap vanes" and generate lift that makes
rocket fly all over the sky (and maybe ground).
* With the correct nose weight, this will weight a few ounces LESS than a Maxi
can fly on an Estes E9-4. I strongly suggest using a 6 foot long 1/4" diameter
to allow the model to build up airspeed.
If you fly it "normal" with a D12 it will go "x" feet high. If you add nose
weight to fly
it safely with an E9-4, it will go a tiny bit higher, but not as high as you
AND every time you fly it with a D12-3 it will then fly lower than it would have
originally designed configuration. Somewhat of a waste.
