Mars Lander question
Another rocket I am in the middle of building is a Mars Lander clone.
My question is about the rubber bands used on the landing gear legs. What is the proper size rubber band for this aplication? I think I'm set with all the other parts, just not sure of what bands to use on it. Again, thanks to all. This is a gold mine of info for all BARs out there! I've been looking for a site like this for a long time. Hans |

Unless you're going for the "authentic look" of an original, I'd suggest using elastic shock chord material instead. This is what Estes is using in their Outlander variation of the ML. Check the Wal Mart crafts section, near the knitting supplies, and you'll fins all of the elastic you'll ever need...

Craig,
Thanks for the advice. I don't know why I did not think of that. Sometimes things stare you right in the face and you miss them! Hans |

I totally agree here with CPMcGraw on this one....go with the shock cord material.
I own two original Mars Landers plus an original unbuilt kit....the one that used the stock rubberbands now has collapsed legs...but it was built 20+ years ago.

So, has anyone actually seen a conversion of an Outlander to a Mars Lander?

Kind of.... Sirius Rocketry sells a decal set that makes your Outlander look like a Mars Lander... http://www.siriusrocketry.com/siriusshopping/sirius01/ Look under "Parts and Accessories - Sirius Parts and Accessories - Elite Line Decal Sets" Here's a link to photos of a built one... http://www.rocketryforum.com/showth...er&pagenumber=3 Later, EV |

re: the Outlander kit ...
can anyone comment on the legs,etc - are they the same as ( or close enough) to the Mars lander ? looks like a good start for a clone, instead of cutting the legs,etc . Might have to add a lander tot he winter project pile .... had one in the wayback but sold it when I was flying exclusively HPR ( and low on cash, lol ) .... ~ AL |

Al, The legs in the Outlander are identical to the Mars Lander's, and it is a good way to clone the MR. Actually, I think the Outlander has slightly thicker foot pad coupler pieces, but that's it; the die-cut and balsa parts are identical. The stuffer tube is the same as well. The toughest part is finding the BT-100 tube. It was also used in the first Estes R2-D2; I got one off eBay a long time ago. It's the same length. If you get that you just need a few centering rings and the balsa nose from BMS and decals (I think Excelsior has them). Check the Mars Lander Yahoo group for shroud patterns. Replicating the embossed panel lines will also be a challenge. Another one of my projects waiting in line. Drew |

The legs are almost exactly the same. The main difference is in the elastic attachment. There's a notch in the leg where the rubber band is placed before the lower strut is attached. The other end of the rubber band hooked around a dowel hidden by the lower shouds. This is what made the rubber band nearly impossible to replace when broken. The Outlander leg has an external attachment, and the other end of the elastic is the external attachment of the opposite leg. This makes the Outlander a tad easier to fix, but it looks kinda chintzy to me. The notch is still represented in the die/laser cut legs, as, I believe, are the holes in the bottom plate where the rubber bands would hook to the dowels, so that much could be used in a conversion. But it's been a while since I compared the two. A minor difference is the pads are 1/4" thick instead of 1/8".
