Functional 1:6th Scale Mars Rover Model
 

Hi Everyone, I've got something a little different for you today.

I'm looking for some very specific information for a project i am working on - the construction of a 1:6th scale Curiosity Mars Rover. So I am not having to custom fabricate everything, I am intending to use stock components from other sources, and right now I am working on the suspension system of the rover.

Unlike in a car where you have roughly 25% sag and 75% compression when the car is sat stationary, I need the shocks to be at 50/50 point, so I have even extensions and compression.

I've not been able to find a website that states the stroke length of the shocks, since everything is based on model type/scale/shock location etc.

So I'd like to know what the stroke length is on all the stand shock sizes.

Another way to look at it is I need one type of shock that is at 50% compression when its ~60-70mm long (Like a Tamiya M Type), and another when its 110mm long (Like a Crawler Shock).

So, hopefully a few of you don't mind getting out a rule and giving their shocks a quick squeeze.

Thanks for reading - E

Mmm daft idea but have you thought on contacting NASA and explaining on what youd like to do and maybe they may help? They are quite approachable.

Don't some crawler shocks come with internal spirngs, if so you could cut the Spring in half put half above the piston and half below?

Maybe air suspension etc would be the way to go as you could then control the pressure to each one?

Sorry if I've misunderstood something:eh?:
