Default CP & CG

Okay after checking the CP and CG with the D12-3 far enough back not to burn the engine bells, puts the CG on the wrong side of the CP. Already overweight, don't want to add weight to the nose if possible. With the E12-4 will be even worse.

Looks like without the engine bells for flight.

All the more reason to build that escape tower.

I predict adding nose weight.

Starting to make sense. Longer arm less weight needed. Just cranked up my design computer.

Already increased the size of the fins.

Peter Alway's book is coming in handy for this project. Little Joe II looks like it has the numbers I'm needing to draw the tower.

Default Life/$$

Life sometimes displaces hobbies.

Been hired to draw a home for a friend. Been busy last two weekends and now this one as well. I'll get back on this project once the home is done.

Didn't want everyone thinking I gave up.

I do have a tower designed and printed. It is very small it won't add much weight. Just more drag. Boost Protective Cover now part of rocket.

Best regards,
Mike Bauer

Any thought of making one in 1/70 scale for those who cannot get the Apogee kit?

Then a 1B in the same scale for those who cannot get the Estes/SEMROC one?
