Ok...so maybe I'm a little late to the game...but the rubber band spring crap...really...after 50 years the SemRoc kit is still doing the same ol same ol....or is everyone doing a real spring modification....kinda like this....
Ok...so this is a common mod then...Weight on the bottom...Baaaaad! Old dudes had to fly on wimpy C6 3 motors for years back in the day. Silly old dudes with thier rubbers!
Mods are awesome but generally uncommon. If you modify kits you have to determine how to counter act the weight you are adding to the hind end and oddrocs like the Mars Lander are the WORST! Then all kinds of nasty rocket science questions arrise. Nose weight for stability? Total weight? Need a bigger motor to lift additional weight? Bigger motor is now heavier, am I back to square one? Are metal srings overkill? Rocket science is hard.Ok...so this is a common mod then...

Spring loaded Semroc Mars Landers are rare. I have never seen one. To think of it, launching for nearly twenty years as a BAR, I have only seen a few Mars Landers fly.
I pick up my 1978 built Mars Lander and the dry internal rubber bands are broken. I cry. Put it back on the shelf. Another 70's shelf queen.
Now all I can do is to jump into my hot tub time machine, go back to the 70's and yell at my twelve year old self "Do the Mods!"Shoulda used springs!
Someone like you ought to be able to make a Mars Lander clone or relative from scratch, I should think. You could show us all how it should have been done.Now all I can do is to jump into my hot tub time machine, go back to the 70's and yell at my twelve year old self "Do the Mods!"
Way too much work. Rather be lazy and buy the Semroc kit with the rubbers. They will last long enough for this old dude.Someone like you ought to be able to make a Mars Lander clone or relative from scratch, I should think. You could show us all how it should have been done.
I think that's a GREAT idea to put the springs in! I have not gotten one of those kits yet but I've thought about it. If I were to make one to actually launch (it's one of those kits that's SOOOO cool, I could buy it, build, and hang it from the ceiling to just admire it like my long discontinued Mini-Mars-Lander which will never be launched, but I might clone it to launch).Ok...so maybe I'm a little late to the game...but the rubber band spring crap...really...after 50 years the SemRoc kit is still doing the same ol same ol....or is everyone doing a real spring modification....kinda like this....
This is probably more efficient than the original design.I made little lugs out of sheet polystyrene and very tiny servo screws and springs on the exterior. The rubber inside is not good and I did not wat to carve it open. So I did this mod to mine.
Good Idea!!! Thanks for the picture too!!!I made little lugs out of sheet polystyrene and very tiny servo screws and springs on the exterior. The rubber inside is not good and I did not wat to carve it open. So I did this mod to mine.
