Just to "clarify" one thing.
When Carl said "Adding all the parts in Sandman's original Mars Lander results in 3.42 oz." Carl wasn't talking about the new SEMROC model that I built, he was talking about an "original" Estes kit that I lent him. BTW...I do want it back.

Well I would just like to say that I am very happy that you did not pass. I have 2 of your kits and will build one soon. I did replace the wraps/ upper rings on my clone with yours. That would move my CG forward. The main body rings in my clone are much lighter than the your rings. My legs do have some wobble in them.
Did I understand that the legs CAN'T be more than 13 1/2 in pad-pad? Mine are at 13 with the lander not resting on them. |

Carl, If you have the full Acrobat just print the .pub file to the Adobe PDF "printer". If you don't have the full Acrobat, send the .pub file to me and I'll convert it to PDF for you.

Thanks, I always thought the wider the better guess I was wrong. BTW its none of my buissnes, but your web site still lists the lander as your best seller- how many have been sold? I hope alot. Thanks mark |

As the legs narrow they sweep back more. The more they sweep back the further back the CP goes. Well, to a point. Actually I'm currently building another Mars lander and I've been thinking of making the foot pads removable for flight. Those landing pads cannot be aerodynamically helpful.

Actually, they can... They provide a measure of drag, which can "effectively" shift the CP rearward without shifting the CG. It's like the tail of a kite, or a drogue chute, hanging out in the breeze. It stabilizes the model at the expense of altitude performance.

I agree. Leave the landing pads on...
